METHOD FOR DIAGNOSING WHETHER AN INFECTION IN A PATIENT IS BACTERIAL OR VIRAL, AS WELL AS KIT CROSS-REFERENCE

[001] This application claims the benefit of provisional application serial number US62 / 346,962, filed on June 7, 2016, the application for which is incorporated herein by reference. DECLARATION REGARDING RESEARCH OR DEVELOPMENT SPONSORED BY THE FEDERAL GOVERNMENT

[002] This invention was made with the support of the Government under contracts AI109662 and AI057229 granted by the National Institute of Health. The government has certain rights over the invention. TECHNICAL FIELD

[003] The present invention relates, in general, to methods for diagnosing bacterial and viral infections. In particular, the invention relates to the use of biomarkers that can distinguish whether a patient with acute inflammation has a bacterial or viral infection. BACKGROUND

[004] Early and accurate diagnosis of infection is crucial to improving patient outcomes and reducing antibiotic resistance. The mortality rate from bacterial sepsis increases by 8% for every hour that antibiotics are delayed1; however, administering antibiotics to patients without bacterial infections increases mortality rates and antimicrobial resistance. The rate of inappropriate antibiotic prescription in the hospital setting is estimated at 30–50%, and would be aided by improved diagnostics2,3. Surprisingly, nearly 95% of patients who received antibiotics for suspected enteric fever had negative cultures4. Currently, there is no gold standard reference point that can broadly determine the presence and type of infection. Thus, the White House established a National Action Plan to Combat Petition 870260069557, dated 07 / 14 / 2026, page 6 / 336 2 / 157 to Antibiotic-Resistant Bacteria, which required point-of-need diagnostic tests to quickly distinguish between bacterial and viral infections5.

[005] Although new molecular diagnostics based on PCR can perform pathogen profiling directly from a blood culture 6, such methods depend on the presence of a sufficient number of pathogens in the blood. Furthermore, they are limited to detecting a distinct range of pathogens. As a result, there is a growing interest in molecular diagnostics that determine the host gene response profile. These include diagnostics that can distinguish the presence of infection compared to inflamed but uninfected patients, such as the 11 'Sepsis Metascore'7 (SMS) gene (which has been validated through several cohorts8) among others9,10. Other groups have focused on gene sets that can distinguish between types of infections, such as viral infections, bacterial infections versus11-13. Tsalik et al.He described a model that distinguishes between all three classes (i.e., uninfected patients and those with bacterial or viral disease), although this model required the measurement of 122 probes14. A Meta-Virus Signature that describes a common response to viral infection has also been previously described, but it contained too many genes (396) for clinical application15. Overall, although great promise has been demonstrated in this field, no host gene expression infection diagnosis has become clinical practice.

[006] Data from these biomarker studies and dozens of other genome-wide expression studies in sepsis and acute infections have been published and deposited for further study in public databases such as the NIH Gene Expression Omnibus (GEO) and the EBI ArrayExpress. This data is a largely untapped resource that can be used for both confirmation and further study. Petition 870260069557, dated 07 / 14 / 2026, page 7 / 336 3 / 157 biomarker validation. It has also been previously shown that our integrated multicohort analysis of gene expression yields robust diagnostic tools for sepsis7, specific types of viral infections15 and active tuberculosis16. Furthermore, these data are also useful as a reference and validation tool for new host gene expression diagnostics17. However, such validation in public data has previously been limited only to those cohorts containing at least two classes of interest (i.e., where a direct comparison between classes is possible), since technical differences between studies make direct comparison of diagnostic scores between cohorts impossible.

[007] There remains a need for sensitive and specific diagnostic tests that can distinguish between bacterial and viral infections. SUMMARY

[0091] Figures 1A and 1B show a summary of Receptor Operating Characteristic (ROC) curves for (Figure 1A) finding and (Figure 1B) direct validation datasets for bacterial / viral metascore. A summary ROC curve is shown in black, with 95% confidence intervals in dark gray.

[0092] Figure 2 shows bacterial / viral scores for COCONUT conormalized whole blood finding datasets. PBMC datasets are left out of Figure 2 because PBMC datasets are expected to have different genetic levels than whole blood. The overall AUC across all whole blood finding datasets is 0.92. Distribution of scores by dataset (dark gray = bacterial, light gray = viral), individual gene levels, and maintenance genes. Petition 870260069557, dated 07 / 14 / 2026, p. 33 / 336 29 / 157 (grayscale) are shown. The dashed line shows a possible global limit. The width of each violin corresponds to the distribution of scores in the given dataset. The vertical bar within each violin extends from the 25th to the 75th, and the white line in the middle shows the average score. The maintenance genes (POLG, ATP6V1B1, and PEG10) show the expected invariance between the post-COCONUT normalization datasets.

[0093] Figures 3A to 3C show an integrated antibiotic decision model (IADM) using conormalized public gene expression data from COCONUT that match the inclusion criteria. Figure 3A shows an IADM scheme. Figure 3B shows a distribution of scores and cutoffs for IADM in conormalized COCONUT data. Figure 3C shows a confusion matrix for diagnosis. Sensitivity to bacterial infection: 94.0%; Specificity to bacterial infection: 59.8%; Sensitivity to viral infection: 53.0%; Specificity to viral infection: 90.6%.

[0094] Figures 4A to 4E show gene expression data. NanoString targeted children with SIRS / sepsis from a GPSSSI cohort never tested with microarrays (total N = 96, of which SIRS = 36, bacterial sepsis = 49, viral sepsis = 11). Figure 4A shows the breakdown of infected patients by organism type. Figures 4B and 4C show ROC curves for SMS and bacterial / viral metascore. Figure 4D shows the distribution of scores and cutoffs for IADM. Figure 4E shows a confusion matrix for IADM; Sensitivity to bacterial infection: 89.7%; Specificity to bacterial infection: 70.0%; Sensitivity to viral infection: 54.5%; Specificity to viral infection: 96.5%.

[0095] Figures 5A and 5B show that the Sepsis Metascore (SMS) alone cannot determine the type of pathogen. The diagram in (Figure 5A) indicates how a decision model can be constructed. A Petition 870260069557, dated 07 / 14 / 2026, p. 34 / 336 30 / 157 Figure 5B shows the distribution of SMS in patients with bacterial versus viral infections. Of 11 datasets, there were only three for which the SMS distribution showed a significant difference between bacterial and viral infections.

[0096] Figure 6 shows a schematic of the workflow for multicohort analysis and determination of the bacterial-viral meta-signature.

[0097] Figure 7 shows forest plots of genes in the bacterial / viral metascore across the findings datasets. The geometric x-axes represent the standardized mean difference between bacterial and viral infection samples, calculated as Hedges' g, on a log2 scale. The size of the black rectangles is inversely proportional to the standard error of the mean in the study. Risk marks represent the 95% confidence interval. The light gray diamonds represent the pooled overall mean difference for a given gene. The width of the diamonds represents the 95% confidence interval of the pooled overall mean difference.

[0098] Figure 8 shows forest plots of the random effects meta-analysis of the alpha and beta summary ROC parameters for the finding datasets. Alpha roughly controls the distance from the identity line (greater alpha = greater AUC) and beta controls the slope of the actual ROC curve (beta = 0 means no slope).

[0099] Figure 9 shows forest plots of the random effects meta-analysis of the alpha and beta summary ROC parameters for the validation datasets. Alpha roughly controls the distance from the identity line (greater alpha = greater AUC) and beta controls the slope of the actual ROC curve (beta = 0 means no slope).

[00100] Figure 10 shows the ROC of bacterial / viral metascore in GSE53166, where monocyte-derived dendritic cells Petition 870260069557, dated 07 / 14 / 2026, page 35 / 336 31 / 157 stimulated in vitro with LPS or influenza virus, total N = 75 (39 LPS, 36 influenza virus).

[00101] Figure 11 shows a schematic representation of COCONUT conormalization. Light gray indicates healthy ('H'), medium gray means viral ('V'), and dark gray means bacterial ('B'). Different crosses mean different batch effects. See Methods for formal mathematical details.

[00102] Figures 12A and 12B show data from whole blood finding datasets. PBMC datasets are left out of Figures 12A and 12B because PBMC datasets are expected to have different genetic levels than whole blood. Figure 12A shows raw data and Figure 12B shows COCONUT conormalized data. COCONUT conormalization redefines each gene to be at the same location and scale for control patients. The distribution of a gene within a dataset is unchanged (the median difference in the T-statistic for healthy versus diseased across datasets is 0, range (-1e-13, 1e-13), across all genes and all datasets). The ATP6V1B1 maintenance gene exhibits the expected invariance with respect to disease and is invariant across datasets after normalization.A gene that is expected to be induced by disease, for example, CEACAM1, exhibits invariance in healthy controls but may vary in disease states among datasets. Upper colored bars indicate datasets; the lower colored bar indicates the disease class.

[00103] Figure 13 shows the bacterial / viral score in the overall ROC conormalization COCONUT of whole blood validation datasets. The overall AUC across all whole blood validation datasets is 0.93. The score distribution by dataset (dark gray violins = bacterial, light gray violins = 0.93) Petition 870260069557, dated 07 / 14 / 2026, p. 36 / 336 32 / 157 = viral) and maintenance genes (grayscale) are shown. The width of each violin corresponds to the distribution of scores in the given dataset. The vertical bar within each violin extends from the 25th to the 75th, and the white line in the middle shows the average score. The dashed line shows a possible global limit. The maintenance genes (POLG, ATP6V1B1, and PEG10) show the expected invariance between the post-COCONUT normalization datasets.

[00104] Figure 14 shows the overall bacterial / viral ROC score of non-connormalized whole blood finding datasets. PBMC datasets are left out of Figure 14 because PBMC datasets are expected to have different genetic levels than whole blood. The overall AUC across all whole blood finding datasets is 0.93. The score distribution by dataset (dark gray violins = bacterial, light gray violin = viral) and maintenance genes (grayscale) are shown. The width of each violin corresponds to the distribution of scores in the given dataset. The vertical bar within each violin extends from the 25th to the 75th, and the middle white dash shows the average score. Note the highly variable locations and scales of the POLG, ATP6V1B1, and PEG10 maintenance genes.

[00105] Figure 15 shows the bacterial / viral score in the overall ROC of non-connormalized whole blood validation datasets. PBMC datasets are left out of Figure 15 due to the fact that PBMC datasets are expected to have different genetic levels than whole blood. The score distribution by dataset (dark gray violins = bacterial, light gray violin = viral) and maintenance genes (grayscale) are shown. The width of each violin corresponds to the distribution of scores in the given dataset. The vertical bar within each violin is Petition 870260069557, dated 07 / 14 / 2026, p. 37 / 336 33 / 157 extends from the 25th to the 75th, and the white line in the middle shows the average score. Note the highly variable locations and scales of the POLG, ATP6V1B1, and PEG10 maintenance genes.

[00106] Figure 16 shows the bacterial / viral score in global ROC of COCONUT conormalization of PBMC validation datasets. The PBMC datasets are examined separately due to the fact that PBMC datasets are expected to have different gene levels than whole blood. The overall AUC across all PBMC validation datasets is 0.92. The score distribution by dataset (dark gray violins = bacterial, light gray violin = viral) and maintenance genes (grayscale) are shown. The dashed line shows a possible global limit. The width of each violin corresponds to the distribution of scores in the given dataset. The vertical bar within each violin extends from the 25th to the 75th, and the middle white dash shows the average score. The maintenance genes (POLG, ATP6V1B1) show the expected invariance between post-COCONUT normalization datasets.

[00107] Figure 17 shows the overall bacterial / viral ROC score of non-conormalized PBMC validation datasets. PBMC datasets are examined separately due to the fact that PBMC datasets are expected to have different gene levels than whole blood. The score distribution across the dataset (dark gray violins = bacterial, light gray violins = viral), individual gene levels, and maintenance genes (grayscale) are shown. The width of each violin corresponds to the distribution of scores in the given dataset. The vertical bar within each violin extends from the 25th to the 75th, and the middle white line shows the average score. The highly variable locations and scales of the POLG and ATP6V1B1 maintenance genes are noted. Petition 870260069557, dated 07 / 14 / 2026, p. 38 / 336 34 / 157

[00109] Figures 19A to 19D show the effects of age on the Sepsis Metascore in conormalized COCONUT data. Figure 19A shows age versus SMS by pathogen type, to assess whether pathogen type is driving age differences in SMS. Figure 19B shows log10(age) vs. SMS by pathogen type, which shows that at age extremes, SMS may have a different attainable maximum. Figure 19C shows log10(age) versus SMS by dataset, which demonstrates that the relationship between age and SMS is independent of dataset. Figures 19A to 19C include only samples from infected patients; Figure 19D shows samples from healthy and uninfected SIRS, in addition to showing the baseline across ages. In all cases, the age data for GSE25504 are randomly distributed according to the mean age determined in their manuscript, approximately 2 weeks, + / - 1 week, to show the data density.All ages = 0 were reset to age = 1 / 365.

[00110] Figures 20A and 20B show the Sepsis Metascore in all whole blood data (both at finding and validation) before (Figure 20B) and after COCONUT conormalization (Figure 20A). The overall AUC is 0.86 (95% CI 0.84 to 0.89) after COCONUT conormalization. The score distribution by dataset (light gray violin = non-infectious inflammation, dark gray violin = infection / sepsis) and maintenance genes (grayscale) are shown. The dashed line shows a possible overall threshold. The width of each violin corresponds to the distribution of scores in the given dataset. The vertical bar within each violin extends from the 25th to the 75th, and the white line in the middle shows the mean score. Note Petition 870260069557, dated 07 / 14 / 2026, page 39 / 336 35 / 157 shows that the invariance of the maintenance genes POLG, ATP6V1B1, and PEG10 in the datasets of Figure 20A post-COCONUT normalization, with highly variable locations and scales of the maintenance genes before normalization in Figure 20B.

[00111] Figures 21A and 21B show IADM using conormalized public gene expression data from COCONUT that includes healthy controls. The included datasets (and cutoffs used) are the same as those in Figures 3A to 3C. Figure 21A shows the distribution of scores for IADM in conormalized COCONUT data. Figure 21B shows a confusion matrix for diagnosis. Sensitivity to bacterial infection: 94.2%; Specificity to bacterial infection: 68.5%; Sensitivity to viral infection: 53.0%; Specificity to viral infection: 94.1%. SIRS refers to non-infectious inflammation.

[00112] Figure 22 shows NPV and PPV versus prevalence for a diagnostic test with a sensitivity of 94.0% and a specificity of 59.8%. The red lines show an NPV of 98.3% with a prevalence of 15%, as a rough estimate of actual infection case rates.

[00113] Figures 23A to 23D show results for the GSE63990 dataset (adults with acute respiratory infections). Figures 23A and 23B show ROC curves for the Sepsis Metascore and the bacterial / viral metascore. Figure 23C shows the distribution of scores and cutoffs for the IADM. Figure 23D shows a confusion matrix for the IADM; Sensitivity to bacterial infection: 94.3%; Specificity to bacterial infection: 52.2%; Sensitivity to viral infection: 52.2%; Specificity to viral infection: 94.3%.

[00116] In the description of the present invention, the following terms shall be used, and shall be defined as indicated below.

[00117] It should be noted that, as used in this descriptive report and the accompanying claims, the singular forms a, an, and others include plural referents, unless the content clearly dictates otherwise. Thus, for example, reference to a biomarker includes a mixture of two or more biomarkers, and the like.

[00118] The term about, particularly in reference to a specific quantity, is intended to cover deviations of plus or minus five percent. Petition 870260069557, dated 07 / 14 / 2026, p. 41 / 336 37 / 157

[00119] The term Area Under the Curve (AUC) as used in this document shall be understood as referring to the area under a Receiving Operating Characteristic Curve (ROC Curve).

[00120] A biomarker in the context of the present invention refers to a biological compound, such as a polynucleotide, that is differentially expressed in a sample taken from patients who have an infection, compared to a comparable sample taken from control individuals (e.g., a person with a negative diagnosis, a normal or healthy individual, or an uninfected individual).

Viral response genes include, but are not limited to, IFI27, JUP, Petition 870260069557, dated 07 / 14 / 2026, p. 42 / 336 38 / 157 LAX1, OAS2, CUL1, ISG15, CHST12, IFIT1, SIGLEC1, ADA, MX1, RSAD2, IFI44L, GZMB, KCTD14, LY6E, IFI44, HESX1, OASL, OAS1, OAS3, EIF2AK2, DDX60, DNMT1, HERC5, IFIH1, SAMD9, IFI6, IFIT3, IFIT5, XAF1, ISG20, PARP12, IFIT2, DHX58 and STAT1.

[00122] Bacterial response genes refer to genes that are differentially expressed in a sample of patients with a bacterial infection compared to a comparable sample from a control group (e.g., a person with a negative diagnosis, a normal or healthy individual, or an uninfected individual). Bacterial response genes include, but are not limited to, HK3, TNIP1, GPAA1, CTSB, SLC12A9, ACPP, STAT5B, EMR1, FLII, PTAFR, NRD1, PLP2, DYSF, TWF2, SORT1, TSPO, TBXAS1, ACAA1, S100A12, PGD, LAPTM5, NINJ2, DOK3, SORL1, RAB31, IMPA2, LTA4H, TALDO1, TKT, PYGL, CETP, PROS1, RTN3, CAT, and CYBRD1.

[00123] Sepsis response genes refer to genes that are differentially expressed in a sample taken from patients who have sepsis or an infection, compared to a comparable sample taken from control subjects (e.g., a person with a negative diagnosis, normal or healthy or uninfected individuals). Sepsis response genes include, but are not limited to, CEACAM1, ZDHHC19, C9orf95, GNA15, BATF, C3AR1, KIAA1370, TGFBI, MTCH1, RPGRIP1, and HLA-DPB1.

[00124] The terms polypeptide and protein refer to a polymer of amino acid residues and are not limited to a minimum length. Thus, peptides, oligopeptides, dimers, multimers, and the like are included in the definition. Both whole proteins and their fragments are covered by the definition. The terms also include post-expression modifications of the polypeptide, for example, glycosylation, acetylation, phosphorylation, hydroxylation, oxidation, and the like. Petition 870260069557, dated 07 / 14 / 2026, p. 43 / 336 39 / 157

[00125] The terms polynucleotide, oligonucleotide, nucleic acid, and nucleic acid molecule are used in this document to include a polymeric form of nucleotides of any length, ribonucleotides, or deoxyribonucleotides. This term refers only to the primary structure of the molecule. Thus, the term includes triple-stranded, double-stranded, and single-stranded DNA, as well as triple-stranded, double-stranded, and single-stranded RNA. It also includes modifications, such as by methylation and / or capping, and unmodified forms of the polynucleotide. More particularly, the terms polynucleotide, oligonucleotide, nucleic acid, and nucleic acid molecule include polydeoxyribonucleotides (containing 2-deoxy-D-ribose), polyribonucleotides (containing D-ribose), and any other type of polynucleotide that is a N- or C-glycoside of a purine or pyrimidine base.There is no intended distinction in terms of length between the terms polynucleotide, oligonucleotide, nucleic acid, and nucleic acid molecule, and these terms are used interchangeably.

[00126] The term differentially expressed refers to differences in the amount and / or frequency of a biomarker present in a sample from patients who have, for example, an infection (e.g., viral infection or bacterial infection) compared to a control individual or an uninfected individual. For example, a biomarker might be a polynucleotide that is present at a high level or a low level in samples from patients with an infection (e.g., viral infection or bacterial infection) compared to samples from control individuals. Alternatively, a biomarker might be a polynucleotide that is detected with a higher frequency or a lower frequency in samples from patients with an infection (e.g., viral infection or bacterial infection) compared to samples from control individuals. A biomarker can be differentially expressed in terms of Petition 870260069557, dated 07 / 14 / 2026, page 44 / 336 40 / 157 quantity, frequency, or both.

[00127] A polynucleotide is differentially expressed between two samples if the amount of the polynucleotide in one sample is statistically different, by a method significant, from the amount of the polynucleotide in the other sample. For example, a polynucleotide is differentially expressed in two samples if it is present at least about 120%, at least about 130%, at least about 150%, at least about 180%, at least about 200%, at least about 300%, at least about 500%, at least about 700%, at least about 900%, or at least about 1,000% greater than it is present in the other sample, or if it is detectable in one sample and not detectable in the other.

[00128] Alternatively or additionally, a polynucleotide is differentially expressed in two sets of samples if the frequency of detection of the polynucleotide in samples from patients suffering from sepsis is statistically higher or lower, by a significant method, than in control samples. For example, a polynucleotide is differentially expressed in two sets of samples if detected at least about 120%, at least about 130%, at least about 150%, at least about 180%, at least about 200%, at least about 300%, at least about 500%, at least about 700%, at least about 900%, or at least about 1,000% more frequently or less frequently observed in one set of samples than the other set of samples.

[00129] A similarity value is a number that represents the degree of similarity between two things being compared. For example, a similarity value might be a number that indicates the overall similarity between a patient's expression profile using specific phenotype-related biomarkers and reference value ranges for the biomarkers in one or more control samples or Petition 870260069557, dated 07 / 14 / 2026, page 45 / 336 41 / 157 a reference expression profile (e.g., similarity to a viral infection expression profile or a bacterial infection expression profile). The similarity value can be expressed as a similarity metric, such as a correlation coefficient, or it can simply be expressed as the expression level difference or the aggregate of expression level differences between biomarker levels in a patient sample and a control sample or reference expression profile.

[00130] The terms individual, subject, and patient are used interchangeably herein and refer to any mammalian individual for whom diagnosis, prognosis, treatment, or therapy is desired, particularly humans. Other individuals may include cattle, dogs, cats, guinea pigs, rabbits, rats, mice, horses, and so forth. In some cases, the methods of the invention will be used on experimental animals, in veterinary applications, and in the development of animal models for disease, including, but not limited to, rodents including mice, rats, and hamsters; and primates.

[00131] As used in this document, a biological sample refers to a sample of tissue, cells or fluid isolated from an individual, including but not limited to, for example, blood, buffy coat, plasma, serum, blood cells (e.g., peripheral blood mononuclear cells (PBMCs)), fecal matter, urine, bone marrow, bile, spinal fluid, lymphatic fluid, skin samples, external skin secretions, respiratory, intestinal and genitourinary tract secretions, tears, saliva, milk, organs, biopsies and also samples of constituents of in vitro cell culture, which includes, but is not limited to, conditioned media resulting from the growth of cells and tissues in culture medium, for example, recombinant cells and cellular components. Petition 870260069557, dated 07 / 14 / 2026, page 46 / 336 42 / 157

[00132] A test quantity of a biomarker refers to the amount of a biomarker present in a sample that is tested. A test quantity can be an absolute quantity (e.g., pg / ml) or a relative quantity (e.g., relative signal intensity).

[00133] A diagnostic quantity of a biomarker refers to an amount of a biomarker in an individual's sample that is consistent with the diagnosis of an infection (e.g., viral or bacterial infection). A diagnostic quantity can be an absolute quantity (e.g., pg / ml) or a relative quantity (e.g., relative signal intensity).

[00134] A control quantity of a biomarker can be any quantity or a range of quantities that is to be compared with a test quantity of a biomarker. For example, a control quantity of a biomarker could be the quantity of a biomarker in a person without an infection (e.g., viral infection or bacterial infection). A control quantity can be in absolute quantity (e.g., μg / ml) or in relative quantity (e.g., relative signal intensity).

[00135] The term antibody encompasses preparations of polyclonal and monoclonal antibodies, as well as preparations including hybrid antibodies, altered antibodies, chimeric antibodies and humanized antibodies, as well as: hybrid (chimeric) antibody molecules (see, for example, Winter et al.

(1992) Biochem 31: 1579 to 1584; Cumber et al. (1992) J Immunology 149B: 120 to 126); humanized antibody molecules (see, for example, Riechmann et al. (1988) Nature 332: 323 to 327; Verhoeyan et al. (1988) Science 239: 1534 to 1536; and UK Patent Publication in GB 2,276,169, published on 21 September 1994); and any functional fragments obtained from these molecules, wherein these fragments retain specific binding properties of the parental antibody molecule.

[00136] Detectable portions or detectable markers contemplated for use in the invention include, but are not limited to, radioisotopes, fluorescent dyes such as fluorescein, phycoerythrin, Cy-3, Cy-5, allophycin, DAPI, Texas Red, rhodamine, Oregon Green, Lucifer Yellow and the like, green fluorescent protein (GFP), red fluorescent protein (DsRed), cyan fluorescent protein (CFP), yellow fluorescent protein (YFP), Cerianthus orange fluorescent protein (cOFP), alkaline phosphatase (AP), beta-lactamase, chloramphenicol acetyltransferase (CAT), adenosine deaminase (ADA), aminoglycoside phosphotransferase (neor, G418r), dihydrofolate reductase (DHFR), hygromycin-B-phosphotransferase (HPH), thymidine kinase (TK), lacZ (encoding β-alactosidase) and xanthine guanine phosphoribosyltransferase (XGPRT), beta-glucuronidase (gus), placental alkaline phosphatase (PLAP), secreted embryonic alkaline phosphatase (SEAP), or firefly or bacterial luciferase (LUC).Enzyme labels are used with their cognate substrate.

[00142] Although various methods and materials similar or equivalent to those described in this document may be used in the practice of the present invention, the preferred materials and methods are described in this document.

[00143] The invention is based on the discovery of biomarkers that can be used for the diagnosis of an infection (see Example 1). In particular, the invention relates to the use of biomarkers that can be used to determine whether a patient with acute inflammation has a bacterial or viral infection that would benefit from treatment with an antibiotic or antiviral agent. In order to further understand the invention, a more detailed discussion is provided below on the identified biomarkers and the methods for Petition 870260069557, dated 07 / 14 / 2026, p. 50 / 336 46 / 157 use the same in the diagnosis and treatment of infections. A. BIOMARKERS

[00145] In one aspect, the invention includes a diagnostic method. Petition 870260069557, dated 07 / 14 / 2026, p. 51 / 336 47 / 157 of an infection in a patient. The method comprises a) obtaining a biological sample from the patient; b) measuring the expression levels in the biological sample of a set of viral response genes showing differential expression associated with a viral infection and a set of bacterial response genes showing differential expression associated with a bacterial infection; and c) analyzing the expression levels of the viral response genes and the bacterial response genes together with their respective reference ranges.

[00146] When analyzing biomarker levels in a biological sample, reference value ranges may represent the levels of one or more biomarkers found in one or more samples from one or more individuals without an infection (e.g., healthy or uninfected individual). Alternatively, reference values ​​may represent the levels of one or more biomarkers found in one or more samples from one or more individuals with a viral or bacterial infection. In certain embodiments, biomarker levels are compared to corresponding time reference value ranges for uninfected or infected individuals.

[00148] The biological sample obtained from the patient to be diagnosed is typically whole blood or blood cells (e.g., PBMCs), but it can be any sample of body fluids, tissue, or cells containing the expressed biomarkers. A control sample, as used herein, refers to a biological sample, such as body fluid, tissue, or cells that are not diseased. That is, a control sample is obtained from a normal or uninfected individual (e.g., an individual known not to have a viral infection, bacterial infection, sepsis, or inflammation). A biological sample can be obtained from a patient by conventional techniques. For example, blood can be obtained by venipuncture, and solid tissue samples can be obtained by surgical techniques according to methods well known in the art.

[00149] In certain modalities, a panel of biomarkers Petition 870260069557, dated 07 / 14 / 2026, p. 53 / 336 49 / 157 is used for the diagnosis of an infection. Biomarker panels of any size can be used in the practice of the invention. Biomarker panels for diagnosing an infection typically comprise at least 3 biomarkers and up to 30 biomarkers, including any number of intermediate biomarkers, such as 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29 or 30 biomarkers. In certain embodiments, the invention includes a biomarker panel comprising at least 3, or at least 4, or at least 5, or at least 6, or at least 7, or at least 8, or at least 9, or at least 10, or at least 11 or more biomarkers. While smaller biomarker panels are generally more economical, larger biomarker panels (i.e., more than 30 biomarkers) have the advantage of providing more detailed information and can also be used in the practice of the invention.

[00150] In certain embodiments, the invention includes a biomarker panel for diagnosing an infection comprising one or more polynucleotides comprising a nucleotide sequence of a gene or an RNA transcript of a gene selected from the group consisting of IFI27, JUP, LAX1, HK3, TNIP1, GPAA1 and CTSB. In another embodiment, the biomarker panel further comprises one or more polynucleotides comprising a nucleotide sequence of a gene or an RNA transcript of a gene selected from the group consisting of CEACAM1, ZDHHC19, C9orf95, GNA15, BATF, C3AR1, KIAA1370, TGFBI, MTCH1, RPGRIP1 and HLADPB1.

[00151] In certain modalities, biomarkers to distinguish viral and bacterial infections, as described in this document, are combined with additional biomarkers that have the ability to distinguish the possibility of inflammation in an individual. Petition 870260069557, dated 07 / 14 / 2026, p. 54 / 336 50 / 157 can be caused by an infection or a non-infectious source of inflammation (e.g., traumatic injury, surgery, autoimmune disease, thrombosis, or systemic inflammatory response syndrome (SIRS)). A first diagnostic test is used to determine whether the acute inflammation is caused by an infectious or non-infectious source, and whether the source of the inflammation is an infection. A second diagnostic test is used to determine whether the infection is a viral infection or a bacterial infection that will benefit from treatment with antiviral agents or antibiotics, respectively.

[00152] In one embodiment, the invention includes a method for diagnosing and treating a patient having inflammation, comprising the method: a) obtaining a biological sample from the patient; b) measuring the expression levels of the biomarkers IFI27, JUP, LAX1, HK3, TNIP1, GPAA1, CTSB, CEACAM1, ZDHHC19, C9orf95, GNA15, BATF, C3AR1, KIAA1370, TGFBI, MTCH1, RPGRIP1 and HLA-DPB1 in the biological sample;(ec) first analyze the expression levels of each biomarker together with the respective reference value ranges for the biomarkers, where increased expression levels of the biomarkers CEACAM1, ZDHHC19, C9orf95, GNA15, BATF, and C3AR1 and reduced expression levels of the biomarkers KIAA1370, TGFBI, MTCH1, RPGRIP1, and HLA-DPB1, compared to the reference value ranges for the biomarkers for an uninfected control individual, indicate that the patient has an infection, and the absence of differential expression of the biomarkers CEACAM1, ZDHHC19, C9orf95, GNA15, BATF, C3AR1, KIAA1370, TGFBI, MTCH1, RPGRIP1, and HLA-DPB1, compared to the uninfected control individual, indicates that the patient does not have an infection; d) analyze for a second time the expression levels of the biomarkers IFI27, JUP, LAX1, HK3, TNIP1, GPAA1 and CTSB, if the patient is; Petition 870260069557, dated 07 / 14 / 2026, p. 55 / 336 51 / 157 diagnosed as having an infection, where increased expression levels of the biomarkers IFI27, JUP, LAX1 compared to the reference ranges for the biomarkers for a control individual indicate that the patient has a viral infection and increased expression levels of the biomarkers HK3, TNIP1, GPAA1, CTSB compared to the reference ranges for the biomarkers for the control individual indicate that the patient has a bacterial infection; and e) administer an effective amount of an antiviral agent to the patient if the patient is diagnosed with a viral infection, or administer an effective amount of an antibiotic to the patient if the patient is diagnosed with a bacterial infection.

[00153] In another embodiment, the method further comprises calculating a sepsis metascore for the patient, wherein a sepsis metascore greater than the reference ranges for an uninfected control individual indicates that the patient has an infection and a sepsis metascore that is within the reference ranges for an uninfected control individual indicates that the patient has a non-infectious inflammatory condition.

[00154] In another embodiment, the method further comprises calculating a bacterial / viral metascore for the patient if the patient is diagnosed with an infection, wherein a positive bacterial / viral metascore for the patient indicates that the patient has a viral infection and a negative bacterial / viral metascore for the patient indicates that the patient has a bacterial infection.

B. DETECTION AND MEASUREMENT OF BIOMARKERS

[00158] It is understood that biomarkers in a sample can be measured by any suitable method known in the art. The measurement of the expression level of a biomarker can be direct or indirect. For example, the abundance levels of RNAs or proteins can be directly quantified. Alternatively, the amount of a biomarker can be determined indirectly by measuring the abundance levels of cDNAs, amplified RNAs or DNAs, or by measuring the amounts or activities of RNAs, proteins or other molecules (e.g., metabolites) that are indicative of the biomarker's expression level. Methods for measuring biomarkers in a sample have many applications.For example, one or more biomarkers may be measured to aid in the diagnosis of an infection, to determine the appropriate treatment for an individual, to monitor an individual's responses to treatment, or to identify therapeutic compounds that modulate the expression of biomarkers in vivo or in vitro. DETECTION OF BIOMARKER POLINUCLEOTIDES

[00159] In one embodiment, the expression levels of biomarkers are determined by measuring the polynucleotide levels of the biomarkers. The transcript levels of specific biomarker genes can be determined from the amount of mRNA, or Petition 870260069557, dated 07 / 14 / 2026, p. 60 / 336 56 / 157 derived polynucleotides, present in a biological sample. Polynucleotides can be detected and quantified by a variety of methods including, but not limited to, microarray analysis, polymerase chain reaction (PCR), reverse transcriptase polymerase chain reaction (RT-PCR), Northern blot, serial gene expression analysis), RNA switches, and solid-state nanopore detection. See, for example, Draghici Data Analysis Tools for DNA Microarrays, Chapman and Hall / CRC, 2003; Simon et al. Design and Analysis of DNA Microarray Investigations, Springer, 2004; PRealTime PCR: Current Technology and Applications, Logan, Edwards and Saunders, editors, Caister Academic Press, 2009; Bustin AZ of Quantitative PCR (IUL Biotechnology, no. 5), International University Line, 2004; Velculescu et al. (1995) Science 270: 484 to 487; Matsumura et al. (2005) Cell. Microbiol.7: 11 to 18; Serial Gene Expression Analysis (SAGE): Methods and Protocols (Methods in Molecular Biology), Humana Press, 2008; incorporated herein by reference in their entirety.

[00160] In one embodiment, microarrays are used to measure biomarker levels. An advantage of microarray analysis is that the expression of each of the biomarkers can be measured simultaneously, and microarrays can be specifically designed to provide a diagnostic expression profile for a particular disease or condition (e.g., sepsis).

[00161] Microarrays are prepared by selecting probes comprising a polynucleotide sequence and then immobilizing these probes on a support or solid surface. For example, the probes may comprise DNA sequences, RNA sequences, or DNA-RNA copolymer sequences. The polynucleotide sequences of the probes may also comprise DNA and / or RNA analogs, or combinations thereof. For example, the Petition 870260069557, dated 07 / 14 / 2026, p. 61 / 336 57 / 157 Polynucleotide sequences of probes can be complete or partial fragments of genomic DNA. The polynucleotide sequences of the probes can also be synthesized nucleotide sequences, such as synthetic oligonucleotide sequences. The probe sequences can be synthesized enzymatically in vivo, enzymatically in vitro (e.g., by PCR), or non-enzymatically in vitro.

[00162] The probes used in the methods of the invention are preferably immobilized on a solid support that may be porous or non-porous. For example, the probes can be polynucleotide sequences that are covalently attached to a nitrocellulose or nylon membrane or filter at the 3' or 5' end of the polynucleotide. Such hybridization probes are well known in the art (see, for example, Sambrook, et al, Molecular Cloning: A Laboratory Manual (3rd edition, 2001).Alternatively, the support or solid surface may be a glass, silicon, or plastic surface. In one embodiment, hybridization levels are measured in probe microarrays consisting of a solid phase on the surface on which a population of polynucleotides is immobilized, such as a population of DNA or DNA mimic, or alternatively, a population of RNA or RNA mimic. The solid phase may be a non-porous material or, optionally, a porous material, such as a gel, or a porous wafer, such as a TipChip (Axela, Ontario, Canada).

[00163] In one embodiment, the microarray comprises a support or surface with an ordered arrangement of binding sites (e.g., hybridization) or probes, each representing one of the biomarkers described herein. Preferably, the microarrays are addressable arrays and, more preferably, positionally addressable arrays. More specifically, each probe in the array is preferably located at a known predetermined position on the solid support, such that the identity (i.e., Petition 870260069557, dated 07 / 14 / 2026, p. 62 / 336 58 / 157 the sequence) of each probe can be determined from its position in the array (i.e., on the support or surface). Each probe is preferably covalently affixed to the solid support at a single location.

[00164] Microarrays can be made in several ways, several of which are described below. Regardless of how they are produced, microarrays share certain characteristics. Arrays are reproducible, allowing multiple copies of a given array to be produced and easily compared to each other. Preferably, microarrays are made of materials that are stable under binding conditions (e.g., nucleic acid hybridization). Microarrays are, as a general method, small, e.g., between 0.1 cm2 and 25 cm2; however, larger arrays can also be used, e.g., in screening arrays.Preferably, a given binding site or unique set of binding sites in the microarray will specifically bind (i.e., hybridize) to the product of a single gene in a cell (e.g., to a specific mRNA or a specific derived cDNA). However, in general, other related or similar sequences will cross-hybridge to a given binding site.

[00165] As noted above, the probe to which a particular polynucleotide molecule specifically hybridizes contains a complementary polynucleotide sequence. Microarray probes typically consist of nucleotide sequences no longer than 1,000 nucleotides. In some embodiments, the array probes consist of nucleotide sequences from 10 to 1,000 nucleotides. In one embodiment, the nucleotide sequences of the probes are in the range of 10 to 200 nucleotides in length and are genomic sequences of a species of organism, so that a plurality of different probes are present, with complementary sequences and thus have the ability to hybridize to the genome of that species. Petition 870260069557, dated 07 / 14 / 2026, page 63 / 336 59 / 157 of organism, sequentially coated in all or part of the genome. In other embodiments, the probes are in the range of 10 to 30 nucleotides in length, in the range of 10 to 40 nucleotides in length, in the range of 20 to 50 nucleotides in length, in the range of 40 to 80 nucleotides in length, in the range of 50 to 150 nucleotides in length, in the range of 80 to 120 nucleotides in length, or are 60 nucleotides in length.

[00166] Probes may comprise DNA or DNA mimics (e.g., derivatives and analogs) corresponding to a portion of an organism's genome. In another embodiment, the microarray probes are complementary RNA or RNA mimics. DNA mimics are polymers composed of subunits with the capacity for Watson-Crick-like specific hybridization with DNA, or for specific hybridization with RNA. Nucleic acids may be modified in the base chemical portion, the sugar chemical portion, or the phosphate structure (e.g., phosphorothioates).

[00167] DNA can be obtained, for example, by polymerase chain reaction (PCR) amplification of genomic DNA or cloned sequences. PCR primers are preferably chosen based on a known genome sequence that will result in the amplification of specific genomic DNA fragments. Computer programs that are well-known in the art are useful in designing primers with the required specificity and ideal amplification properties, such as Oligo version 5.0 (National Biosciences). Typically, each probe in the microarray will be between 10 and 50,000 bases, generally between 20 and 200 bases in length. PCR methods are well-known in the art and are described, for example, in Innis et al., Editions, PCR Protocols: A Guide To Methods And Applications, Academic Press Inc., San Diego, CA, USA (1990); incorporated herein by reference. Petition 870260069557, dated 07 / 14 / 2026, page 64 / 336 60 / 157 in its entirety. It will be evident to a person versed in the technique that controlled robotic systems are useful for isolating and amplifying nucleic acids.

[00168] A preferred alternative means of generating polynucleotide probes is by synthesis of synthetic polynucleotides or oligonucleotides, for example, using N-phosphonate or phosphoramidite chemistries (Froehler et al., Nucleic Acid Res. 14: 5399 to 5407 (1986); McBride et al., Tetrahedron Lett. 24: 246 to 248 (1983)). The synthetic sequences typically have between about 10 and about 500 bases in length, more typically between about 20 and about 100 bases, and most preferably between about 40 and about 70 bases in length. In some embodiments, the synthetic nucleic acids include non-natural bases, such as, but not limited to, inosine. As noted above, nucleic acid analogs can be used as binding sites for hybridization. An example of a suitable nucleic acid analog is peptide nucleic acid (see, for example, Egholm et al., Nature 363: 566 to 568 (1993); Patent no. US5,539,083).

[00169] Probes are preferably selected using an algorithm that takes into account binding energies, base composition, sequence complexity, cross-hybridization binding energies, and secondary structure. See Friend et al., International Patent Publication WO 01 / 05935, published January 25, 2001; Hughes et al., Nat. Biotech. 19: 342-347 (2001).

[00170] A person skilled in the art will also observe that positive control probes, for example, probes known to be complementary and hybridizable in sequences on the target polynucleotide molecules, and negative control probes, for example, probes known to be non-complementary and non-hybridizable in sequences on the target polynucleotide molecules, should be included in the array. Petition 870260069557, dated 07 / 14 / 2026, p. 65 / 336 61 / 157 In one embodiment, positive controls are synthesized along the perimeter of the array. In another embodiment, positive controls are synthesized in diagonal bands across the array. In yet another embodiment, the inverse complement for each probe is synthesized near the probe position to serve as a negative control. In yet another embodiment, sequences from other species of organisms are used as negative controls or as peak controls.

[00171] The probes are affixed to a support or solid surface, which may be made, for example, of glass, plastic (e.g., polypropylene, nylon), polyacrylamide, nitrocellulose, gel, silicon, or other porous or non-porous material. One method for affixing nucleic acids to a surface is to print on glass plates, as described, in general method, by Schena et al., Science 270: 467 to 470 (1995). This method is especially useful for preparing cDNA microarrays (See also, DeRisi et al., Nature Genetics 14: 457 to 460 (1996); Shalon et al., Genome Res. 6: 639 to 645 (1996); and Schena et al., Proc. Natl. Acad. Sci. EUA 93: 10,539 to 11,286 (1995); incorporated into this document by reference in its entirety).

[00172] A second method for producing microarrays produces high-density oligonucleotide arrays. The techniques are known to produce arrays containing thousands of oligonucleotides complementary to defined sequences, at defined locations on a surface using photolithographic techniques for in situ synthesis (see, Fodor et al., 1991, Science 251: 767-773; Pease et al., 1994, Proc. Natl. Acad. Sci. USA 91: 5022-5026; Lockhart et al., 1996, Nature Biotechnology 14: 1675; US Patents no. 5,578,832; US5,556,752 and US5,510,270, incorporated herein by reference in their entirety) or other methods for the synthesis and rapid deposition of defined oligonucleotides (Blanchard et al., Biosensors & Bioelectronics 11: 687 to 690, incorporated herein). Petition 870260069557, dated 07 / 14 / 2026, p. 66 / 336 62 / 157 document by reference in its entirety). When these methods are used, oligonucleotides (e.g., 60-mers) of known sequence are synthesized directly onto a surface, such as a derivatized glass slide. Typically, the array produced is redundant, with several oligonucleotide molecules per RNA.

[00173] Other methods for making microarrays, for example, by masking (Maskos and Southern, 1992, Nuc. Acids. Res. 20: 1679 to 1684; incorporated herein by reference in its entirety), can also be used. In principle, any type of array, for example, dot blots on a nylon hybridization membrane (see Sambrook, et al., Molecular Cloning: A Laboratory Manual, 3rd edition, 2001) could be used. However, as those versed in the art will recognize, very small sets will often be preferred due to the fact that the hybridization volumes will be smaller.

[00174] Microarrays can also be fabricated using an inkjet printing device for oligonucleotide synthesis, for example, using the methods and systems described by Blanchard in US Patent No. 6,028,189; Blanchard et al., 1996, Biosensors and Bioelectronics 11: 687 to 690; Blanchard, 1998, in Synthetic DNA Arrays in Genetic Engineering, volume 20, J.K. Setlow, Edition, Plenum Press, New York, USA, pages 111 to 123; incorporated herein by reference in its entirety. Specifically, the oligonucleotide probes in such microarrays are synthesized in arrays, for example, on a glass slide, which serially deposits the individual nucleotide bases in microdroplets of a high surface tension solvent, such as propylene carbonate.Microdroplets have small volumes (e.g., 100 µl or less, more preferably 50 µl or less) and are separated from each other in the microarray (e.g., by hydrophobic domains). Petition 870260069557, dated 07 / 14 / 2026, page 67 / 336 63 / 157 form circular surface tension cavities that define the locations of the array elements (i.e., the different probes). Microarrays fabricated by this inkjet method are typically high-density, preferably with a density of at least about 2,500 different probes per 1 cm2. The polynucleotide probes are covalently attached to the support at the 3' or 5' end of the polynucleotide.

[00175] Biomarker polynucleotides that can be measured by microarray analysis can be expressed RNA or a nucleic acid derived from it (e.g., cDNA or amplified cDNA-derived RNA incorporating an RNA polymerase promoter), which includes naturally occurring nucleic acid molecules as well as synthetic nucleic acid molecules. In one embodiment, the target polynucleotide molecules comprise RNA, including, but not limited to, total cellular RNA, poly(A)+ messenger RNA (mRNA) or a weak form thereof, cytoplasmic mRNA, or RNA transcribed from cDNA (i.e., cRNA: see, for example, Linsley & Schelter, patent application serial no. US 09 / 411,074, filed October 4, 1999, or US Patent nos. 5,545,522, US 5,891,636, or US 5,716,785). The methods for preparing poly(A)+ and total RNA are well known in the art and are described, in general terms, for example, in Sambrook, et al.RNA can be extracted from a cell of interest using lysis with guanidine thiocyanate followed by centrifugation with CsCl (Chirgwin et al., 1979, Biochemistry 18: 5294 to 5299), a silica gel-based column (e.g., RNeasy (Qiagen, Valencia, California, USA)) or StrataPrep (Stratagene, La Jolla, California, USA)), or using phenol and chloroform, as described in Ausubel et al., eds., 1989, Current Protocols in Molecular Biology, volume III, Publishing Associates Green, Inc., John Wiley & Sons, Inc., New York, USA. Petition 870260069557, dated 07 / 14 / 2026, page 68 / 336 64 / 157 pages 13.12.1 to 13.12.5). Poly(A)+ RNA can be selected, for example, by selection with cellulose oligo-dT or, alternatively, by reverse transcription initiated with oligo-dT of total cellular RNA. RNA can be fragmented by methods known in the art, for example, by incubation with ZnCl2, to generate RNA fragments.

[00176] In one embodiment, total RNA, mRNA, or nucleic acids derived therefrom are isolated from a sample taken from a patient who has an infection or inflammation. Biomarker polynucleotides that are poorly expressed in particular cells can be enriched using normalization techniques (Bonaldo et al., 1996, Genome Res. 6: 791 to 806).

[00177] As described above, biomarker polynucleotides can be detectably labeled at one or more nucleotides. Any method known in the art can be used to label the target polynucleotides. Preferably, this labeling incorporates the marker uniformly along the length of the RNA, and preferably, the labeling is performed with a high degree of efficiency. For example, polynucleotides can be labeled by oligo-dT-initiated reverse transcription. Random primers (e.g., 9-mers) can be used in reverse transcription to uniformly incorporate labeled nucleotides along the entire length of the polynucleotides. Alternatively, random primers can be used in conjunction with PCR methods or T7 promoter-based in vitro transcription methods to amplify polynucleotides.

[00178] The detectable marker may be a luminescent marker. For example, fluorescent markers, bioluminescent markers, chemiluminescent markers, and colorimetric markers may be used in the practice of the invention. Fluorescent markers that may be used include, but are not limited to, fluorescence, a Petition 870260069557, dated 07 / 14 / 2026, page 69 / 336 65 / 157 phosphorus, a rhodamine, or a polymethine dye derivative. Chemiluminescent markers that can be used include, but are not limited to, luminol. Additionally, commercially available fluorescent markers include, but are not limited to, fluorescent phosphoramidites such as FluorePrime (Amersham Pharmacia, Piscataway, NJ), Fluoredite (Miilipore, Bedford, Massachusetts, USA), FAM (ABI, Foster City, California, USA), and Cy3 or Cy5 (Amersham Pharmacia, Piscataway, NJ, USA). Alternatively, the detectable marker can be a radiolabeled nucleotide.

[00179] In one embodiment, biomarker polynucleotide molecules from a patient sample are differentially labeled from the corresponding polynucleotide molecules from a reference sample. The reference may comprise polynucleotide molecules from a normal biological sample (i.e., control sample, e.g., blood or PBMCs from an individual without infection or inflammation) or from a reference biological sample (e.g., blood or PBMCs from an individual with a viral infection or bacterial infection).

[00180] Hybridization and nucleic acid washing conditions are chosen so that the target polynucleotide molecules specifically bind to or hybridize to the complementary polynucleotide sequences of the array, preferably at a specific location on the array where their complementary DNA is located. Arrays containing double-stranded probe DNA are preferably subjected to denaturation conditions to generate single-stranded DNA before contacting the target polynucleotide molecules. Arrays containing single-stranded probe DNA (e.g., synthetic oligodeoxyribonucleic acids) may need to be denatured before contacting the target polynucleotide molecules, for example, to remove Petition 870260069557, dated 07 / 14 / 2026, p. 70 / 336 66 / 157 staples or dimers that form due to self-complementary sequences.

[00181] Ideal hybridization conditions will depend on the length (e.g., oligomer versus polynucleotide greater than 200 bases) and type (e.g., RNA or DNA) of probe and target nucleic acids. A person skilled in the technique will observe that as oligonucleotides become shorter, it may be necessary to adjust their lengths to obtain a relatively uniform melting temperature for satisfactory hybridization results. General parameters for specific (i.e., stringent) nucleic acid hybridization conditions are described in Sambrook, et al., Molecular Cloning: A Laboratory Manual (3rd edition, 2001), and in Ausubel et al., Current Protocols in Molecular Biology, volume 2, Current Protocols Publishing, New York, USA (1994). Typical hybridization conditions for cDNA microarrays from Schena et al. are 5-fold hybridization.SSC plus 0.2% SDS at 65°C for four hours, followed by washes at 25°C in low-stringency washing buffer (1x SSC plus 0.2% SDS), followed by 10 minutes at 25°C in higher-stringency washing buffer (0.1x SSC plus 0.2% SDS) (Schena et al., Proc. Natl. Acad. Sci. USA 93: 10.614 (1993)). Useful hybridization conditions are also provided in, for example, Tijessen, 1993, Hybridization With Nucleic Acid Probes, Elsevier Science Publishers BV; and Kricka, 1992, Nonnotopic DNA Probe Techniques, Academic Press, San Diego, California, USA. Particularly preferred hybridization conditions include hybridization at a temperature at or near the average melting temperature of the probes (e.g., within 51°C, more preferably within 21°C) in 1 M NaCl, 50 mM MES buffer (pH 6.5), 0.5% sodium sarcosine, and 30% formamide.

[00182] When fluorescently labeled gene products are used, the fluorescence emissions at each site of one. Petition 870260069557, dated 07 / 14 / 2026, p. 71 / 336 67 / 157 microarrays can preferably be detected by confocal laser microscopy scanning. In one embodiment, a separate scan is performed, using the appropriate excitation line, for each of the two fluorophores used. Alternatively, a laser can be used that allows simultaneous illumination of specimens at wavelengths specific to the two fluorophores, and emissions from the two fluorophores can be analyzed simultaneously (see Shalon et al., 1996, A DNA microarray system for analyzing complex DNA samples using two-color fluorescent probe hybridization, Genome Research 6: 639 to 645, which is incorporated herein by reference in its entirety for all purposes). Array scans can be performed with a laser fluorescent scanner with a computer-controlled XY stage and a microscope objective.Sequential excitation of the two fluorophores is achieved with a multiline mixed-gas laser, and the emitted light is divided by wavelength and detected with two photomultiplier tubes. Fluorescence laser scanning devices are described in Schena et al., Genome Res. 6: 639-645 (1996) and in other references cited in this document. Alternatively, the optical fiber array described by Ferguson et al., Nature Biotech. 14: 1681-1684 (1996), can be used to monitor mRNA abundance levels at a large number of sites simultaneously. Alternatively, probes can be labeled with fluorophores and targets measured with quenchers, so that amplification is tracked by measuring the decreasing signal intensity.

[00183] In certain embodiments, the invention includes a microarray comprising a plurality of probes for detecting gene expression of a set of viral response genes and a set of bacterial response genes and / or a set of sepsis response genes. Petition 870260069557, dated 07 / 14 / 2026, p. 72 / 336 68 / 157

[00184] In one embodiment, the microarray comprises an oligonucleotide that hybridizes with an IFI27 polynucleotide, an oligonucleotide that hybridizes with a JUP polynucleotide, an oligonucleotide that hybridizes with a LAX1 polynucleotide, an oligonucleotide that hybridizes with an HK3 polynucleotide, an oligonucleotide that hybridizes with a TNIP1 polynucleotide, an oligonucleotide that hybridizes with a GPAA1 polynucleotide, and an oligonucleotide that hybridizes with a CTSB polynucleotide.

[00185] In another embodiment, the microarray further comprises an oligonucleotide that hybridizes with a CEACAM1 polynucleotide, an oligonucleotide that hybridizes with a ZDHHC19 polynucleotide, an oligonucleotide that hybridizes with a C9orf95 polynucleotide, an oligonucleotide that hybridizes with a GNA15 polynucleotide, an oligonucleotide that hybridizes with a BATF polynucleotide, an oligonucleotide that hybridizes with a C3AR1 polynucleotide, an oligonucleotide that hybridizes with a KIAA1370 polynucleotide, an oligonucleotide that hybridizes with a TGFBI polynucleotide, an oligonucleotide that hybridizes with an MTCH1 polynucleotide, an oligonucleotide that hybridizes with an RPGRIP1 polynucleotide, and a an oligonucleotide that hybridizes with an HLA-DPB1 polynucleotide.

[00186] Polynucleotides can also be analyzed by other methods including, but not limited to, Northern blotting, nuclease protection assays, RNA detection, polymerase chain reaction, ligase chain reaction, Qbeta replicase, isothermal amplification method, chain displacement amplification, transcription-based amplification systems, nuclease protection (S1 or RNase nuclease protection assays), SAGE, as well as methods disclosed in International Publications WO 88 / 10315 and WO 89 / 06700, and International Applications PCT / US87 / 00880 and Petition 870260069557, dated 07 / 14 / 2026, page 73 / 336 69 / 157 PCT / US89 / 01025; incorporated herein by reference in its entirety.

[00187] A standard Northern blot assay can be used to determine RNA transcript size, identify alternatively split RNA transcripts, and the relative amounts of mRNA in a sample, according to conventional Northern hybridization techniques known to people of ordinary skill in the art. In Northern blots, RNA samples are first separated by size by agarose gel electrophoresis under denaturing conditions. The RNA is then transferred to a membrane, cross-linked, and hybridized with a labeled probe. Radiolabeled probes of high specific activity or non-isotopic can be used, including randomly generated, nick-translated, or PCR-generated DNA probes, in vitro transcribed RNA probes, and oligonucleotides. In addition, sequences with only partial homology (e.g., cDNA from a different species or genomic DNA fragments that may contain an exon) can be used as probes.The labeled probe, for example, a radiolabeled cDNA containing full-length single-stranded DNA or a fragment of that DNA sequence, may be at least 20, at least 30, at least 50, or at least 100 consecutive nucleotides long. The probe may be labeled by any of the many different methods known to those skilled in this technique. The most commonly employed markers for these studies are radioactive elements, enzymes, chemicals that fluoresce when exposed to ultraviolet light, and others. A number of fluorescent materials are known and can be used as markers. These include, but are not limited to, fluorescein, rhodamine, auramine, Texas Red, AMCA Blue, and Lucifer Yellow. A particular detection material is anti-rabbit antibody prepared in goats and conjugated with fluorescein via... Petition 870260069557, dated 07 / 14 / 2026, page 74 / 336 70 / 157 isothiocyanate. Proteins can also be labeled with a radioactive element or enzyme. The radioactive label can be detected by any of the currently available counting procedures. Isotopes that can be used include, but are not limited to, 3H, 14C, 32P, 35S, 36Cl, 35Cr, 57Co, 58Co, 59Fe, 90Y, 1251, 1311 and 186Re. Enzymatic labels are equally useful and can be detected by any of the currently used colorimetric, spectrophotometric, fluorophotometric, amperometric or gasometric techniques. The enzyme is conjugated to the selected particle by reaction with binding molecules such as carbodiimides, diisocyanates, glutaraldehyde and the like. Any enzymes known to a person skilled in the art can be used. Examples of such enzymes include, but are not limited to, peroxidase, beta-D-galactosidase, urease, glucose oxidase plus peroxidase, and alkaline phosphatase. Patents in US3,654,090, US3.752 and US4,016,043 are referred to by way of example for their disclosure of alternative material and marking methods.

[00188] Nuclease protection assays (which include both ribonuclease protection assays and S1 nuclease assays) can be used to detect and quantify specific mRNAs. In nuclease protection assays, an antisense probe (labeled with, for example, radiolabeled or non-isotopic) hybridizes in solution with an RNA sample. After hybridization, the unhybridized single-stranded probe and RNA are degraded by nucleases. An acrylamide gel is used to separate the remaining protected fragments. Typically, solution hybridization is more effective than membrane-based hybridization, and it can accommodate up to 100 pg of sample RNA, compared to the 20 to 30 pg maximum of blot hybridizations.

[00189] The ribonuclease protection assay, which is the most Petition 870260069557, dated 07 / 14 / 2026, page 75 / 336 71 / 157 common nuclease protection assay requires the use of RNA probes. Oligonucleotides and other single-stranded DNA probes can only be used in assays containing S1 nuclease. The single-stranded antisense probe must typically be fully homologous to the target RNA to avoid probe:target hybrid cleavage by nuclease.

[00190] Serial Gene Expression Analysis (SAGE) can also be used to determine RNA abundances in a cell sample. See, for example, Velculescu et al., 1995, Science 270: 484-487; Carulli, et al. 1998, Journal of Cellular Biochemistry Supplements 30 / 31: 286-296; incorporated herein by reference in its entirety. SAGE analysis does not require a special detection device and is one of the preferred analytical methods for simultaneously detecting the expression of a large number of transcription products. First, poly A+ RNA is extracted from the cells. Then, the RNA is converted to cDNA using a biotinylated oligo(dT) primer and treated with a four-base recognition restriction enzyme (Docking Enzyme: AE) resulting in AE-treated fragments containing a biotin group at their 3' end. Next, the fragments treated with AE are incubated with streptavidin for binding.The ligated cDNA is split into two fractions, and each fraction is then ligated to a different double-stranded oligonucleotide adapter (linker) A or B. These linkers are composed of: (1) a projecting single-stranded portion that has a sequence complementary to the projecting portion sequence formed by the action of the anchoring enzyme, (2) a 5' nucleotide recognition sequence of type IIS restriction enzyme (cleaves at a predetermined site no more than 20 bp from the recognition site) that serves as a labeling enzyme (TE), and (3) an additional sequence of sufficient length to construct a primer. Petition 870260069557, dated 07 / 14 / 2026, p. 76 / 336 72 / 157 specific to PCR. The ligand-bound cDNA is cleaved using a labeling enzyme, and only the ligand-bound portion of the cDNA sequence remains, which is present as a short-strand sequence marker. Then, sets of short-strand sequence markers from the two different types of ligands are ligated together, followed by PCR amplification using primers specific for ligands A and B. As a result, the amplification product is obtained as a mixture comprising a myriad of sequences from two adjacent sequence markers (ditags) bound to ligands A and B. The amplification product is treated with an anchoring enzyme, and the free ditag portions are ligated into strands in a standard ligation reaction. The amplification product is then cloned. The nucleotide sequence determination of the clone can be used to obtain a reading of consecutive ditags of constant length.The presence of mRNA corresponding to each marker can then be identified from the nucleotide sequence of the clone and the information about the sequence markers.

[00191] Quantitative reverse transcriptase PCR (qRT-PCR) can also be used to determine biomarker expression profiles (see, for example, Patent Application Publication No. US2005 / 0048542A1; incorporated herein by reference in its entirety). The first step in gene expression profiling by RT-PCR is the reverse transcription of the RNA template into cDNA, followed by its exponential amplification in a PCR reaction. The two most commonly used reverse transcriptases are avian myeloblastosis virus reverse transcriptase (AMV-RT) and Moloney murine leukemia virus reverse transcriptase (MLV-RT). The reverse transcription step is typically initiated using specific primers, random hexamers, or oligo-dT primers. Petition 870260069557, dated 07 / 14 / 2026, page 77 / 336 73 / 157 depending on the circumstances and the objective of the expression profile. For example, the extracted RNA can be reverse transcribed using a GeneAmp RNA PCR kit (Perkin Elmer, California, USA), following the manufacturer's instructions. The derived cDNA can then be used as a template in the subsequent PCR reaction.

[00192] Although the PCR step can use a variety of thermostable DNA-dependent DNA polymerases, it typically employs Taq DNA polymerase, which has 5'-3' nuclease activity but lacks 3'-5' proofreading endonuclease activity. Thus, TAQMAN PCR typically utilizes the 5' nuclease activity of Taq or Tth polymerase to hydrolyze a hybridization probe bound to its target amplification product, but any enzyme with equivalent 5' nuclease activity can be used. Two oligonucleotide primers are used to generate a typical amplicon of a PCR reaction. A third oligonucleotide, or probe, is designed to detect the nucleotide sequence located between the two PCR primers. The probe is not extensible by the Taq DNA polymerase enzyme and is labeled with a fluorescent reporter dye and a fluorescent quenching dye.Any laser-induced emission from the reporter dye is quenched by the quenching dye when the two dyes are located close to each other, as they are in the probe. During the amplification reaction, the Taq DNA polymerase enzyme cleaves the probe in a template-dependent manner. The resulting probe fragments dissociate in solution, and the signal from the released reporter dye is free from the abrupt cooling effect of the second fluorophore. One molecule of reporter dye is released for each new molecule synthesized, and the detection of the non-abruptly cooled reporter dye provides the basis for the quantitative interpretation of the data.

[00193] TAQMAN RT-PCR can be performed using the Petition 870260069557, dated 07 / 14 / 2026, page 78 / 336 74 / 157 commercially available equipment, such as, for example, the ABI PRISM 7700 sequence detection system (Perkin-Elmer-Applied Biosystems, Foster City, California, USA), or the Lightcycler (Roche Molecular Biochemicals, Mannheim, Germany). Alternatives include, but are not limited to, point-of-use sample-to-response devices, such as the cobas Liat system (Roche Molecular Diagnostics, Pleasanton, California, USA) or the GeneXpert system (Cepheid, Sunnyvale, California, USA). A person of ordinary skill in the art will observe that the invention is not limited to the devices listed, and that other devices may be used for TAQMAN-PCR. In a preferred embodiment, the 5' nuclease procedure is performed on a real-time quantitative PCR device, such as the ABI PRISM 7700 sequence detection system. The system consists of a thermocycler, laser, charge-coupled device (CCD), camera, and computer.The system includes software to run the instrument and analyze the data. Data from the 5' nuclease assay are initially expressed as Ct, or the cycle threshold. Fluorescence values ​​are recorded during each cycle and represent the amount of product amplified up to that point in the amplification reaction. The point at which the fluorescent signal is first recorded as statistically significant is the cycle threshold (Ct). Alternatives to the standard thermal cycle include, but are not limited to, continuous thermal gradient amplification, or isothermal amplification with endpoint detection, and other devices known to those of common skill. To minimize errors and the effect of sample-to-sample variation, RT-PCR is often performed using an internal standard. The ideal internal standard is expressed at a constant level across different tissues and is unaffected by experimental treatment.RNAs most frequently used to normalize gene expression patterns are mRNAs for the glyceraldehyde-3-phosphate maintenance genes. Petition 870260069557, dated 07 / 14 / 2026, page 79 / 336. 75 / 157 dehydrogenase (GAPDH) and beta-actin.

[00194] A more recent variation of the RT-PCR technique is quantitative real-time PCR, which measures the accumulation of PCR products through a dual fluorogenic probe (i.e., TAQMAN probe). Real-time PCR is compatible with both competitive quantitative PCR, in which the internal competitor for each target sequence is used for normalization, and comparative quantitative PCR, in which a normalization gene contained in the sample, or a maintenance gene for RT-PCR, is used. For more details see, for example, Held et al., Genome Research 6: 986 to 994 (1996).

[00195] One alternative is the detection of PCR products using digital counting methods. These include, but are not limited to, digital droplet PCR and solid-state nanopore detection of PCR products. In these methods, the counts of the products of interest can be normalized to the counts of maintenance genes. Other PCR detection methods known to those of common skill in the art may be used, and the invention is not limited to the methods listed. BIOMARKER DATA ANALYSIS

[00196] Biomarker data can be analyzed by a variety of methods to identify biomarkers and determine the statistical significance of differences in observed biomarker levels between test profiles and reference expression, in order to assess whether a patient has inflammation originating from a non-infectious source, such as traumatic injury, surgery, autoimmune disease, thrombosis, or systemic inflammatory response syndrome (SIRS), or an infection, and if the patient is diagnosed with an infection, to diagnose the type of infection, including determining whether a patient has a viral or bacterial infection. In certain modalities, patient data are analyzed by one or more methods including, but not limited to, Petition 870260069557, dated 07 / 14 / 2026, page 80 / 336 76 / 157 limited to multivariate linear discriminant analysis (LDA), receptor operating characteristic (ROC) analysis, principal component analysis (PCA), ensemble mining methods, microarray significance analysis (SAM), cell-specific microarray significance analysis (csSAM), density-normalized event extension tree progression analysis (SPADE), and multidimensional protein identification technology (MUDPIT) analysis.

[00197] In yet another aspect, the invention provides kits for diagnosing an infection in an individual, wherein the kits can be used to detect the biomarkers of the present invention. For example, the kits can be used to detect any one or more of the biomarkers described herein, which are differentially expressed in samples from a patient who has an infection.

The kit may also include a package insert containing written instructions for infection diagnosis methods.

[00203] The kits of the invention have several applications. For example, the kits can be used to determine if an individual has an infection or some other inflammatory condition resulting from a non-infectious source, such as traumatic injury, surgery, autoimmune disease, thrombosis, or systemic inflammatory response syndrome (SIRS). If a patient is diagnosed with an infection, the kits can be used to further determine the type of infection (i.e., viral or bacterial infection).

In another example, the kits can be used to monitor the effectiveness of treatment for a patient with an infection. In yet another example, the kits can be used to identify compounds that modulate the expression of one or more biomarkers in in vitro or in vivo animal models to determine the effects of treatment. D. DIAGNOSTIC SYSTEM AND COMPUTERIZED METHODS FOR DIAGNOSING AN INFECTION

[00204] In another aspect, the invention includes a computer-implanted method for diagnosing a patient suspected of having an infection. The computer performs steps comprising: receiving entered patient data comprising values ​​for the expression levels of one or both of a set of viral response genes and a set of bacterial response genes in a biological sample from the patient; analyzing the expression levels of the gene set; calculating a bacterial / viral metascore for the patient based on the gene set expression levels, where the bacterial / viral metascore value indicates the likelihood of the patient having a viral infection or a bacterial infection; and displaying information about the patient's diagnosis.

[00208] In another embodiment, the invention includes a computer-implanted method for diagnosing a patient who has inflammation, wherein the computer performing the steps comprises: a) receiving entered patient data including values ​​for the levels of the biomarkers IFI27, JUP, LAX1, HK3, TNIP1, GPAA1, CTSB, CEACAM1, ZDHHC19, C9orf95, GNA15, BATF, C3AR1, KIAA1370, TGFBI, MTCH1, RPGRIP1 and HLA-DPB1 in a biological sample from the patient; b) analyzing the levels of each of the biomarkers and comparing them with the respective reference value ranges for the biomarkers; c) Calculate a sepsis metascore for the patient, where a sepsis metascore greater than the reference value ranges for an uninfected control individual indicates that the patient has an infection, and a sepsis metascore within the reference value ranges for uninfected control subjects indicates that the patient has a non-infectious inflammatory condition; d) Calculate a metascore Petition 870260069557, dated 07 / 14 / 2026, page 86 / 336 82 / 157 bacterial / viral for the patient if the sepsis score indicates that the patient has an infection, where a positive bacterial / viral metascore for the patient indicates that the patient has a viral infection and a negative bacterial / viral metascore for the patient indicates that the patient has a bacterial infection; and ee) display information about the patient's diagnosis.

[00209] In another aspect, the invention includes a diagnostic system for performing the computer-implanted method as described. A diagnostic system includes a computer containing a processor, a storage component (i.e., memory), a display component, and other components normally present in general-purpose computers. The storage component stores information accessible by the processor, which includes instructions that can be executed by the processor and data that can be retrieved, manipulated, or stored by the processor.

[00210] The storage component includes instructions for determining the patient's diagnosis. For example, the storage component includes instructions for calculating a viral / bacterial metascore and / or sepsis metascore, as described in this document (see Example 1). In addition, the storage component may further comprise instructions for performing multivariate linear discriminant analysis (LDA), ROC (receptor operating characteristic) analysis, principal component analysis (PCA), dataset mining methods, microarray cell-specific significance analysis (csSAM), or multidimensional protein identification technology (MUDPIT) analysis. The computer processor is coupled to the storage component and configured to execute the instructions stored in the storage component in order to receive patient data and Petition 870260069557, dated 07 / 14 / 2026, page 87 / 336 83 / 157 Analyze patient data according to one or more algorithms. The display component shows information about the patient's diagnosis.

[00211] The storage component can be of any type that has the capacity to store information accessible by the processor, such as a hard disk, memory card, ROM, RAM, DVD, CD-ROM, USB Flash drive, write-capable and read-only memories. The processor can be any known processor, such as processors from Intel Corporation. Alternatively, the processor can be a dedicated controller, such as an ASIC.

[00212] Instructions can be any set of instructions to be executed directly (as machine code) or indirectly (as scripts) by the processor. In this sense, the terms instructions, steps, and programs can be used interchangeably in this document. Instructions can be stored in object code form for direct processing by the processor, or in any other computer language, including scripts or collections of independent source code modules that are interpreted on demand or compiled in advance.

[00213] Data can be retrieved, stored, or modified by the processor according to instructions. For example, although the diagnostic system is not limited by any particular data structure, data can be stored in computer records, in a relational database as a table with a plurality of different fields and records, XML documents, or simple files. Data can also be formatted in any computer-readable format, such as, but not limited to, binary, ASCII, or Unicode values. Furthermore, data can include any information sufficient to identify the information. Petition 870260069557, dated 07 / 14 / 2026, page 88 / 336 84 / 157 relevant, such as numbers, descriptive text, proprietary codes, indicators, references to data stored in other memories (including other network locations) or information that is used by a function to calculate the relevant data.

[00214] In certain embodiments, the processor and storage component may comprise multiple processors and storage components that may or may not be housed within the same physical housing. For example, some of the instructions and data may be stored on a removable CD-ROM and others within a read-only computer chip. Some or all of the instructions and data may be stored in a physically remote location, but still accessible by the processor. Similarly, the processor may, in fact, include a collection of processors that may or may not operate in parallel.

[00215] In one aspect, a computer is a server that communicates with one or more client computers. Each client computer may be configured similarly to the server, with a processor, storage component, and instructions. Each client computer may be a personal computer, intended for use by one person, which has all the internal components normally found in a personal computer, such as a central processing unit (CPU), display (e.g., a monitor that displays information processed by the processor), CD-ROM, hard disk, user input device (e.g., mouse, keyboard, touch screen, or microphone), speakers, modem and / or network interface device (telephone, cable, or other), and all components used to connect these elements to each other and allow them to communicate (directly or indirectly) with each other.Furthermore, computers, according to the systems and methods described in this document, may comprise any device with a... Petition 870260069557, dated 07 / 14 / 2026, page 89 / 336 85 / 157 capacity to process instructions and transmit data to and from humans and other computers, including network computers without local storage capability.

[00216] Although client computers can comprise a full-size personal computer, many aspects of the system and method are particularly advantageous when used in connection with mobile devices capable of wirelessly exchanging data with a server on a network such as the Internet. For example, the client computer could be a wireless-enabled PDA, such as a Blackberry, Apple iPhone, Android, or other mobile phone with Internet access capability. In this sense, the user can input information using a small keyboard, a keyboard, a touchscreen, or any other means of user input. The computer may have an antenna to receive a wireless signal.

[00217] The server and client computers have the capability for direct and indirect communication, as in a network. Although only a few computers may be used, it should be noted that a typical system may include a large number of connected computers, where each different computer is on a different node of the network. The network, and intermediate nodes, may comprise various combinations of devices and communication protocols, including the Internet, World Wide Web, intranets, virtual private networks, wide area networks, local area networks, cellular networks, private networks using proprietary communication protocols from one or more companies, Ethernet, WiFi, and HTTP. This communication can be facilitated by any device with the capability to transmit data to and from other computers, such as modems (e.g., dial-up or cable), wireless networks, and interfaces. The server may be a web server.

[00218] Although certain advantages are gained when the Petition 870260069557, dated 07 / 14 / 2026, page 90 / 336 86 / 157 information is transmitted or received, as mentioned above, other aspects of the system and method are not limited to any particular way of transmitting information. For example, in some aspects, information may be sent via a disk, tape, flash drive, DVD, or CD-ROM. In other aspects, information may be transmitted in a non-electronic format and entered manually into the system. Furthermore, although some functions are indicated as occurring on a server and others on a client, several aspects of the system and method may be implemented by a single computer with a single processor. III. EXPERIMENT

[00219] Below are examples of specific embodiments for carrying out the present invention. The examples are offered for illustrative purposes only and are not intended to limit the scope of the present invention in any way.

[00220] Efforts have been made to ensure accuracy with regard to the numbers used (e.g., quantities, temperatures, etc.), but some experimental errors and deviations must, of course, be allowed for. EXAMPLE 1 Robust classification of bacterial and viral infections through integrated host gene expression diagnostics. INTRODUCTION

[00221] Here, the aim is to improve the diagnostic power of the Sepsis Metascore (SMS) by adding the ability to discriminate between bacterial and viral infections. Thus, in order to derive a new biomarker to discriminate infection types, a multi-cohort analysis framework was applied to clinical microarray cohorts that compared the host response to bacterial and viral infections. Petition 870260069557, dated 07 / 14 / 2026, page 91 / 336 87 / 157 Furthermore, a new method was developed to conormalize gene expression data across multiple cohorts, allowing for direct comparison of a diagnostic score across multiple cohorts. Finally, the Sepsis MetaScore and the new bacterial / viral diagnosis were combined into an integrated antibiotic decision model (IADM) that can determine the likelihood of a patient with acute inflammation from any source having an underlying bacterial infection. RESULTS DERIVATION OF THE 7-GENE BACTERIAL / VIRAL METASCORE

[00222] The previously published 11-gene SMS cannot reliably differentiate between bacterial and viral infections, showing mainly non-significant differences in score distribution between patients with bacterial and viral infections (Figures 5A and 5B). Given that a conserved host genetic response to viral infections has been previously shown15, it is presumed that a classifier for bacterial vs. viral infections would allow for an improved diagnostic model. Thus, a systematic search was conducted for gene expression microarray cohorts that studied patients with viral and / or bacterial infections. Eight cohorts11,18-26 (both whole blood and PBMC) were identified, which included N>5 patients with both viral and bacterial infections (Table 1A).The 8 cohorts are composed of 426 patient samples (142 viral and 284 bacterial infections), including children and adults, medical and surgical patients, and those with multiple infection sites. A multi-cohort analysis was performed on the 8 cohorts, as previously described (Figure 6)7,15,16,27. Significance thresholds of an effect size >2 times and an FDR <1% were established in a round-robin analysis of a single dataset output. However, in order to ensure that none of the tissue types were influencing the results, only genes that also had a size of [missing value] were selected. Petition 870260069557, dated 07 / 14 / 2026, page 92 / 336 88 / 157 effect >1.5 times in separate analyses of PBMCs and whole blood cohorts. This process resulted in 72 genes being expressed significantly differently (Supplementary Table 1). A greedy breakthrough search7 was then used to find a set of genes optimized for diagnosis, resulting in 7 genes (higher in viral infections: IFI27, JUP, LAX1, higher in bacterial infections: HK3, TNIP1, GPAA1, CTSB; Figure 7). As expected, a bacterial / viral metascore based on these 7 genes robustly distinguished viral from bacterial infections in all 8 finding cohorts (summary ROC AUC = 0.97, 95% CI = 0.89 to 0.99, Figure 1A, Figure 8).

[00223] The set of 7 genes was then tested in the remaining 6 independent clinical cohorts13,14,28-30 that directly compared bacterial and viral infections (total of 341 samples, 138 bacterial and 203 viral), and a ROC summary and AUC of 0.91 (95% CI = 0.82 to 0.96) was found (Table 1B, Figure 1B, Figure 9). As a signature generalization test, the possibility that cells stimulated in vitro with LPS or influenza virus could be separated with bacterial / viral metascore (GSE5316631, N = 75, AUC = 0.99) Figure 10) was also tested. GLOBAL VALIDATION THROUGH COCONUT STANDARDIZATION

[00224] There are dozens of microarray cohorts in the public domain that have studied bacterial or viral infections, but not both, thus preventing a direct (within-dataset) estimate of the diagnostic power to distinguish between bacterial and viral diseases. In order to apply and compare a genetic score across these cohorts, a new method was needed that could remove batch effects between datasets while remaining unbiased regarding the diagnosis of patients with disease. Here, Petition 870260069557, dated 07 / 14 / 2026, page 93 / 336 89 / 157 A new type of array normalization was conceived and implemented that uses empirical Bayes normalization methods from ComBat32 in healthy controls to obtain bias-free corrections of disease samples (a method we call Combat CONormalization with Use of Controls, or COCONUT, Methods section below and Figure 11). Essentially, maintenance genes are invariant across both disease and cohorts after COCONUT conormalization, while each gene still maintains the same distribution between disease and controls within each dataset (Figures 12A and 12B). Since the method assumes that all healthy samples are derived from the same distribution, whole blood and PBMC samples were split, as different immune cell types have significantly different baseline gene expression distributions.Using COCONUT conormalization, it was possible to show that the bacterial / viral metascore has an overall AUC of 0.92 (95% CI 0.89 to 0.96) in the finding cohorts (Figure 2, prenormalized data in Figure 14). This method was then applied to test the bacterial / viral metascore in all publicly available microarray cohorts that met the inclusion criteria and used whole blood (including the four direct validation cohorts that included control patients and 20 cohorts that measured bacterial or viral infections, but not both33-49, N = 143 + 897 = 1,040), and exhibited an overall ROC AUC = 0.93 (95% CI 0.91 to 0.94) in all these data (Table 2, Figure 13, prenormalized data in Figure 15). The wide clinical variety of the data, which includes a broad range of infection types (Gram-positive, Gram-negative, atypical bacterial, common respiratory viruses, and dengue) and severities (mild infections to septic shock), is particularly noteworthy.Thus, a single cutoff point can be established across all cohorts (shown as horizontal dashed lines). Finally, the following was carried out... Petition 870260069557, dated 07 / 14 / 2026, p. 94 / 336 90 / 157 separately, the same process in the available PBMC validation cohorts (6 cohorts50-54, N = 259, overall AUC = 0.92 (95% CI 0.87 to 0.97, Figure 16, pre-normalized data in Figure 17). Notably, all three overall ROC AUCs using COCONUT conormalization (finding whole blood = 0.92, validation whole blood = 0.93, validation PBMC = 0.92) roughly matched the summary AUC of the direct validation cohorts (0.91), providing high confidence at this level of diagnostic power.

[00225] Supplementary Table 4 shows bacterial / viral metascores for all combinations of two (2) genes selected from the set of 71 genes obtained by iterating the greedy advancement algorithm on finding datasets. All combinations of 2 genes in the set of 71 genes show a mean AUC obtained greater than or equal to 0.80 (>0.80). In comparison, Figure 18 shows the distribution of mean AUCs in finding datasets for ten thousand (10,000) randomly chosen pairs of 2 genes, where they show that an AUC greater than or equal to 0.80 is not obtainable by chance alone. As illustrated in Figure 18, the randomly chosen pairs of 2 genes result in a normally limited mean AUC distribution greater than 0.2 (>0.20) and less than 0.80 (<0.80).The combinations of 2 genes provided in Supplementary Table 4 with an AUC equal to or greater than 0.80 (>0.80) are a clinically useful determination of the likelihood of an infection being viral or bacterial. Integrated antibiotic decision model

[00226] A key clinical need is to diagnose the possibility that a patient with signs and symptoms of inflammation may have an underlying bacterial infection, since the rapid and decisive administration of antibiotics is fundamental to improving patient outcomes. Neither SMS nor the bacterial / viral metascore alone Petition 870260069557, dated 07 / 14 / 2026, page 95 / 336 91 / 157 can robustly distinguish between all three classes of (1) non-infectious inflammation, (2) bacterial disease, and (3) viral disease. Thus, to increase clinical relevance, an integrated antibiotic decision model (IADM) was tested, whereby the previously described SMS7 was first applied to test for the presence of an infection, and then samples that tested positive for infection were tested with the bacterial / viral metascore (Figure 3A). As above, the only way to establish test characteristics for IADM simultaneously across cohorts is to use COCONUT conormalization. However, SMS in COCONUT conormalized data was found to be strongly influenced by age, which may be due to differences between healthy patients or infected patients, or both (Figures 19A and 19B). Thus, cohorts focused on infants (children <1 year of age) were excluded from IADM, resulting in a total of 20 cohorts (N = 1,057).The resulting global AUC for SMS from the available data was 0.86 (95% CI 0.84 to 0.89) (Supplementary Table 2, Figures 20A and 20B). Global thresholds were established for an SMS sensitivity for infection of 95% and a bacterial / viral metabolite sensitivity for bacterial infection of 95%. This yielded a global sensitivity and specificity for bacterial infections of 94.0% and 59.8%, respectively, and for viral infections of 53.0% and 90.6%, respectively (Figures 3A to 3C). These were virtually unchanged if healthy patients were included in the uninfected class (Figures 21A and 21B). The overall positive and negative odds ratios for bacterial infection in the IADM are therefore 2.34 (LR+) and 0.10 (LR-); where a recent meta-analysis of procalcitonin showed a negative LR of 0.29 (95% CI 0.22 to 0.38)55. Plotted NPV and PPV vs.prevalence for these test characteristics; where the NPV and PPV for bacterial infection at a prevalence of 15% are 98.3% and 29.2% (Figure 22). Petition 870260069557, dated 07 / 14 / 2026, p. 96 / 336 92 / 157

[00227] There was only one dataset (GSE6399014) that included patients with uninfected SIRS and patients with bacterial and viral disease, but did not include healthy controls, preventing their addition to the overall calculations. Therefore, the IADM was tested with locally derived test thresholds. Overall bacterial infection sensitivity and specificity of 94.3% and 52.2%, respectively, were found (Figures 21A and 21B). Nanostring Validation

[00228] Finally, NanoString nCounter56 gene expression assays were used to validate these results in independent whole blood samples from children with sepsis from the Genomic of Pediatric SIRS and Septic Shock Investigators (GPSSSI) cohort (total N = 96, with 36 SIRS, 49 patients with bacterial sepsis, and 11 patients with viral sepsis, Figures 4A to 4E). The GPSSSI cohort was also used by the GSE66099 dataset, but the profiled children were never described by microarray and therefore are not part of the findings datasets. In the NanoString validation cohort, the SMS AUC was 0.81 (AUC of 0.80 in GSE66099). Similarly, the bacterial / viral metascore AUC was 0.84 (AUC of 0.83 in GSE66099). The AUCs of the microarrays are thus preserved when tested with a targeted gene expression assay in new patients.Applying the same IADM, the sensitivity and specificity for bacterial infections were 89.7% and 70.0%, and for viral infections were 54.5% and 96.5%, respectively. DISCUSSION.

[00229] Improved diagnostics for acute infections are needed in both hospital and outpatient settings. In low-acuity outpatient settings, a simple diagnosis that can distinguish between bacterial and viral infections may be sufficient to assist in the appropriate use of antibiotics. In higher-acuity settings, the Petition 870260069557, dated 07 / 14 / 2026, page 97 / 336 93 / 157 causes of non-infectious inflammation become more important to rule out, and therefore, a decision model for antibiotic prescription should include a non-infected (non-healthy) case. Thus, a reliable diagnosis needs to distinguish all three cases (non-infected inflammation, bacterial infection, and viral infection). Here, using 426 samples from 8 cohorts, a set of only 7 genes was derived that can accurately discriminate bacterial from viral infections across a wide range of clinical conditions in independent cohorts (a total of 30 cohorts composed of 1,299 patients). It is further demonstrated that by coupling the previous Sepsis Metascore (to distinguish the presence or absence of infection) to this new bacterial / viral metascore (to determine the type of infection) in a single integrated antibiotic decision model, it is possible to determine with high precision which patients would benefit from antibiotics.Finally, the diagnostic power of the 7-gene set and IADM in independent samples was confirmed using a targeted NanoString assay, showing that the signatures retain diagnostic power when they are not microarray-dependent.

[00230] The IADM has a low negative likelihood ratio (0.10) and a high estimated NPV, meaning it would potentially be effective as a screening test. Notably, a meta-analysis of procalcitonin that included 3,244 patients from 30 studies resulted in an overall estimated negative likelihood ratio of 0.29 (95% CI 0.22 to 0.38)55. Thus, the negative likelihood ratio of IADM is significantly lower than the estimate for procalcitonin. Furthermore, these test characteristics assume no knowledge of the patient and are therefore only estimates of the actual clinical utility of such a test. History and physical, vital, and laboratory signs would also aid in diagnosis. Even with these caveats, a recent economic decision model for patient screening in Petition 870260069557, dated 07 / 14 / 2026, page 98 / 336 94 / 157 Studies in the ICU for hospital-acquired infections suggested that a test like the IADM, which can accurately diagnose bacterial and viral infections, could be cost-effective.57 Ultimately, only interventional tests will have the capacity to establish the economic and clinical utility of a new diagnostic.

[00231] The diagnosis in pediatric sepsis patients from the GPSSSI cohort was validated using a NanoString assay. NanoString is highly accurate and a useful tool for measuring the expression levels of multiple genes at once; however, it is also likely too slow for clinical application (4–6 hours per assay). Thus, while the assay confirms that the gene pool is robust in targeted measurements, further work is needed to improve turnaround time. Several possibilities exist for an eventual commercial product based on rapid multiplexed qPCR. However, this technical hurdle is something that all gene expression infection diagnostics must overcome to achieve clinical relevance.

[00232] Several groups have published models for diagnosing infections based on host gene expression; none have yet done so in clinical practice. Most previous classifiers were not tested on multiple independent cohorts, had too many genes to allow the rapid profiling needed for useful diagnosis, or both. For example, Suarez et al. created a K-classifier of 10 closest genes, but did not test it outside the published dataset (GSE60244)13. Tsalik et al. created a 122-probe (120-gene) classifier based on multiple regression models, but when testing it on external GEO cohorts, they retrained their regression coefficients on each new dataset14. Such model retraining resulted in a strong upward skewing for these validation numbers (assuming a final model would not be Petition 870260069557, dated 07 / 14 / 2026, page 99 / 336 95 / 157 locally retrained), or suggests that each new clinical site would have to assemble a large prospective cohort to train the model before deployment. Other groups have made gene expression classifiers for sepsis, but have not included models to discriminate viral infections7,9,10. The new IADM is robust across a wide range of disease types and severity, but has relatively lower sensitivity to viral infections. Non-genetic expression biomarkers have also been used for infection diagnosis. Procalcitonin has been extensively studied in the diagnostic context of sepsis, but fails to distinguish between uninfected individuals and those with viral infections58. Protein panel assays have been shown to discriminate bacterial from viral infections, but cannot discriminate patients with non-infectious inflammation59,60.Thus, all these classifiers have certain strengths and weaknesses that will become more apparent with further prospective testing and direct comparison.

[00233] Although the aim of this study was to identify new biomarkers and not necessarily new biology, it is still important that a set of biomarkers has biological plausibility. Of the seven genes in the bacterial / viral metascore, six have been previously associated with infections or leukocyte activation. Both IFI27 and JUP have been shown in single-cohort genome-wide expression studies to be induced in response to viral infection52,61, while TNIP1 and CTSB have been shown to be important in modulating NF-kB and necrotic responses to bacterial infection62,63. Finally, LAX1 (upregulated in viral infections) is involved in the activation of T cells and B cells64, while HK3 is fundamental in the neutrophil differentiation pathway65. Thus, the role of these transcripts as biomarkers for the type of infection is new, but not without precedent. Petition 870260069557, dated 07 / 14 / 2026, page 100 / 336 96 / 157

[00234] A new method, COCONUT, was relied upon to directly compare the model across a huge cluster of single-class cohorts that, by another method, would not be usable for comparison of a new diagnosis. COCONUT assumes that all controls result from the same distribution; that is, the genes of each control group are redefined to have the same mean and variance, with batch parameters learned empirically from gene clusters. This method corrects for microarray and batch processing differences between cohorts and thus allows the creation of a global ROC curve with a single threshold. This is a more realistic measure of diagnostic power than simply reporting multiple validation ROC curves, since no single cohort could obtain the same test characteristics across different cohorts16.The most important aspects of the COCONUT conormalized data are that both the bacterial / viral metascore and the IADM retain diagnostic power across a wide range of infection types and severities, with overall AUCs that are similar to the summary AUCs of close comparisons within cohorts.

[00235] Overall, proven multicohort analysis pipelines were leveraged to obtain a highly robust model for improving infection diagnosis. Using a novel method, this was validated in dozens of independent microarray cohorts. The use of a targeted NanoString assay in pediatric patients with sepsis was also validated. While IADM still needs to be optimized for rapid turnaround as well as prospective interventional testing, it seems evident that host genome molecular profiling will become part of the clinical toolkit in the future.

[00236] A person versed in the technique will understand that alternative methods to bacterial / viral meta-scoring can be used to develop a classifier with the ability to distinguish between Petition 870260069557, dated 07 / 14 / 2026, p. 101 / 336 97 / 157 bacterial and viral infections. Any machine learning method known in the art can be used to develop the classifier. The method of developing a classifier can include clustered algorithms that are made up of a multitude of algorithms, such as logistic regression, support vector machines, and decision trees, such as random forests and gradient-boosting decision trees. Classification can be developed using neural networks, which include a large number of nodes arranged in layers, where the output of a node in the first layer is used as input for a node in the next layer. Alternatively, classification can be developed using a support vector machine model, which is a representation of the examples as points in space, mapped in such a way that the examples of the separate categories are divided by the widest possible empty gap.New examples are then mapped onto the same space and predicted to belong to a category based on which side of the gap the new examples fall on. A person versed in the technique will understand that any number of machine learning algorithms can be used to develop a classification with the ability to distinguish between a bacterial and viral infection. METHODS SYSTEMATIC RESEARCH AND MULTICORT ANALYSIS

[00237] A systematic search was conducted in NIH GEO and EBI ArrayExpress for genome-wide public expression studies of the human microarray using the search terms: bact[wildcard], vir[wildcard], infection, sepsis, SIRS, ICU, nosocomial, fever, pneumonia. Abstracts were screened to remove all studies that were (1) nonclinical, (2) performed using tissues other than whole blood or PBMCs, or (3) patients compared who were not matched by clinical time. Petition 870260069557, dated 07 / 14 / 2026, page 102 / 336 98 / 157

[00238] All microarray data were renormalized from raw data (when available) using standardized methods. Affymetrix arrays were renormalized using gcRMA (in arrays with perfect-matching probes) or RMA. Illumina, Agilent, GE, and other commercial arrays were renormalized using normal exponential background correction followed by quantile normalization. Custom arrays were not renormalized. Data were log2 transformed, and a fixed-effects model was used to summarize probes to genes within each study. Within each study, cohorts tested with different microarray types were treated as independent.

[00239] Multicohort meta-analysis was performed, as previously described7,15,16,27. Briefly, genes were summarized using Hedges' g, and the DerSimonian-Laird random-effects model was used for meta-analysis, followed by Benjamini-Hochberg multiple hypothesis correction66. Patients with bacterial infections were compared to patients with viral infections in studies, such that a positive effect size indicates that a gene was more expressed in virus-infected patients, and a negative effect size indicates that a gene was more expressed in bacteria-infected patients.

[00240] In order to identify a set of genes highly conserved in differential expression between bacterial and viral infections, all cohorts that directly compared patients with bacterial and viral infections were selected. Patients with documented co-infections (i.e., bacterial and viral) were removed. Cohorts were required to have > 5 patients in each group to be included in the meta-analysis. Both PBMCs and whole blood cohorts were included. Significant genes were those that had an effect of Petition 870260069557, dated 07 / 14 / 2026, page 103 / 336 99 / 157 size >2 times and an FDR <1% in a round-robin analysis of the output dataset. However, in order to ensure that both tissue types were represented in the final gene set, separate meta-analyses of the PBMCs and whole blood cohorts were also performed, and all genes that had an effect size <1.5 times in either tissue type were removed separately. The remaining genes were considered significant. Derivation of the set of 7 genes

[00241] To find a set of highly diagnostic genes, significant genes from the meta-analysis were run through direct and greedy searching, as described previously7. Briefly, this algorithm starts with zero genes and in each cycle adds one gene that best improves the AUC for diagnosis in the finding cohorts, until a new gene cannot improve the finding AUC by more than a threshold. The resulting genes are used to calculate a single bacterial / viral metascore, calculated as the geometric mean of the viral response genes minus the geometric mean of the bacterial response genes, times the ratio of the number of genes in each set. The resulting continuous score can then be tested for diagnostic power using ROC curves. DERIVATION OF ADDITIONAL SETS OF GENES

[00242] In order to identify additional sets of diagnostic genes, a recursive greedy advance search was implemented, in which, at the conclusion of the algorithm, the resulting set of diagnostic genes was removed from the possible set of significant genes, and the algorithm was run again. The first set of genes was taken for further validation, but it was observed that the other sets of genes were run similarly in the finding cohorts (Supplementary Table 3). Petition 870260069557, dated 07 / 14 / 2026, p. 104 / 336 100 / 157 DIRECT VALIDATION OF THE SET OF 7 GENES

[00243] The resulting gene pool was first validated in the remaining public gene expression cohorts, which directly compared bacterial to viral infections, but were too small to be used in the meta-analysis. Two cohorts (GSE6024413 and GSE6399014) were released after the completion of our meta-analysis, and thus were used for validation. To demonstrate generalizability, a large in vitro dataset comparing LPS with influenza exposure in monocyte-derived dendritic cells was also examined, but this was not included in the abbreviated AUC as it is not expected to result from the same distribution as the clinical studies. SUMMARY ROC CURVES

[00244] For both verification and validation cohorts, summary ROC curves were constructed according to the method of Kester and Buntinx67, and previously described16. Briefly, linear exponential models are made of each ROC curve, and the parameters of these individual curves are summarized using a random effects model to estimate the overall parameters of the summary ROC curve. The alpha parameter controls the AUC (in particular, the distance of the line from the identity line) and the beta parameter controls the skewness of the ROC curve. The confidence intervals of the summary AUC are estimated from the standard error of alpha and beta in the meta-analysis. COCONUT STANDARDIZATION

[00245] There are dozens of public microarray cohorts that feature profiles of bacterial or viral infections, but not both. It would be advantageous to be able to compare a genetic score between these cohorts, but this has not been possible previously due to the fact that each different microarray has widely different background measurements for Petition 870260069557, dated 07 / 14 / 2026, page 105 / 336 101 / 157 each gene and, among studies using the same types of microarrays, there are large batch effects. In order to use these data, it is necessary to conormalize these cohorts so that: (1) no bias is introduced that could influence the final classification (i.e., the normalization protocol must be blind to the diagnosis); (2) there should be no change in the distribution of a gene within a study; and (3) a gene should show the same distributions across studies after normalization. A method with these characteristics would allow the genetic score to be calculated and compared across multiple studies and thus allow for broad testing of its generalizability.

[00246] The Bayes empirical normalization method32 is popular for cross-platform normalization, but crucially falls short of the desired criteria due to the fact that it assumes an equal distribution across disease states.Thus, a modified version of the ComBat method was developed that conormalizes control samples from different cohorts to allow direct comparison of disease samples from the same cohorts. This method is called CONormalization with the Use of Controls, or COCONUT. COCONUT makes a strong assumption, which is that it forces healthy / control patients from different cohorts to represent the same distribution. In short, all cohorts are divided into healthy and diseased components. The healthy components undergo ComBat conormalization without covariates. The estimated ComBat parameters α, β, σ, δ* and y* are obtained for each dataset for the healthy component and then applied to the diseased component (Figure 10).This forces the diseased components of all cohorts to be from the same background distribution, but maintains their relative distance from the healthy component (the T-statistics in the datasets are only different after COCONUT due to floating-point mathematics). Essentially, this one also requires none. Petition 870260069557, dated 07 / 14 / 2026, page 106 / 336 102 / 157 prior knowledge of disease classification (i.e., bacterial or viral infection), thus meeting pre-specified criteria. This method has the notable requirement that healthy / control patients need to be present in a dataset in order to be grouped with other available data. Furthermore, once healthy / control patients are established to be in the same distribution, they should only be used when this assumption is reasonable (i.e., within the same tissue type, among the same species, etc.). The Combat Model and the Coconut Method

[00247] As described by Johnson et al., the ComBat model corrects for the location and scale of each gene by first solving a common least squares model for gene expression, and then decreasing the resulting parameters using an iteratively solved empirical Bayes estimator32. Formally, it is assumed that each gene expression level Yijg (for gene g for sample j in batch i) is composed of overall gene expression ag, sample condition design matrix X with regression coefficients β9, additive and multiplicative batch effects y / ge õig, and an error term £ijg: =ffç + + Yig 5

[00248] Estimating parameters using common least squares regression standardizes Yijg to a new term Zijg (where ogé is the standard deviation of ε^): 7_ Yijg ~

[00249] The standardized data are now distributed according to:

[00250] ν(υ^> whereYlffΝ(Χι>τι) and gamajn_ verse(A,6 / ) Petition 870260069557, dated 07 / 14 / 2026, page 107 / 336 103 / 157

[00251] The inverse gamma is assumed to be a non-informative prior pattern. The remaining hyperparameters are estimated empirically, with the derivation and solution found in the original reference32. The estimated batch effects can then be used to fit the standardized data to an empirical Bayes-adjusted batch final output. *\q

[00252] In this modified version of this method (COCONUT), all the above items are executed according to the original method without modification. However, it is applied only to healthy / control patients in each dataset (i.e., Y is a matrix of only samples of healthy patients). The estimated parameters aÇ / 3' aÇ δ* ey* are all taken and applied directly to a matrix D consisting only of samples of patients with disease (which must be ordered in the same way as Y): "_ ~ &q ~ --q±^qf * \ DifW “ ~ Xtdj) + %

[00253] In this way, a batch-corrected version of samples with disease D* can be obtained, which corrects for differences between healthy controls, but does not alter each submatrix Di in relation to each Y. GLOBAL ROCS

[00254] COCONUT conormalization was used to test (1) all finding cohorts and (2) all validation cohorts, even those containing only bacterial or only viral disease. This was done separately for PBMC and whole blood data. Petition 870260069557, dated 07 / 14 / 2026, p. 108 / 336 104 / 157 for the reasons described above. After conormalization, the distributions for the individual cohorts were plotted together to allow direct comparison. For each plot, we showed (1) the distribution of scores for each dataset, (2) the normalized gene expression levels for each gene within the diagnostic test, and (3) maintenance genes that show no difference between classes based on meta-analysis. Healthy patients were removed from these plots. However, to show that gene distributions between healthy and diseased patients within cohorts do not change after COCONUT conormalization, we also showed plots with both types of patients with both target genes and maintenance genes (Figure 11). Genes with minimum effect size and minimum variance in the meta-analysis were selected as maintenance genes.

[00255] For each comparison, a single global ROC AUC was calculated and a single threshold was set to allow an estimate of the actual diagnostic performance of the tests. The thresholds for the cutoffs for bacterial versus viral infection were adjusted to approximate a sensitivity for bacterial infection of 90%, since a false negative bacterial infection (i.e., the recommendation not to give antibiotics when antibiotics are needed) can be devastating. INTEGRATED ANTIBIOTIC DECISION MODEL

[00256] The SMS can discriminate patients with severe acute infections from those with inflammation from other sources; however, it cannot distinguish between infection types (Figures 5A and 5B). Therefore, an integrated antibiotic decision model (IADM) was tested, in which the 11-gene SMS is applied, followed by the 7-gene bacterial / viral metascore. This model identifies (1) the likelihood of a patient having an infection, and (2) if so, what type of infection is present (bacterial or viral). It was not possible Petition 870260069557, dated 07 / 14 / 2026, page 109 / 336 105 / 157 identify sufficient validation cohorts with patients with non-infectious inflammation that also included healthy controls, so that, in constructing the global ROCs, the finding and validation cohorts were used. Using COCONUT conormalization, global thresholds were established in all included cohorts, and these were applied to each individual dataset to test the IADM's ability to correctly distinguish patients with non-infectious inflammation, bacterial infection, and viral infection. Healthy patients were not included as a diagnostic class, since they were used in the conormalization procedure. The IADM was also applied separately to all cohorts that did not have healthy controls but included (1) patients with non-infectious SIRS and (2) patients with bacterial and viral infections.

[00257] Since the positive and negative predictive values ​​(PPV and NPV) depend on prevalence, and the prevalence of the data used here does not correspond to the prevalence of infections in a hospital setting, the PPV and NPV curves were calculated based on the sensitivity and specificity for bacterial infections obtained with the integrated antibiotic decision model. Formally, NPV = specificity x (prevalence 1) / ((sensitivity 1) x prevalence + specificity x (prevalence 1)); PPV = sensitivity x prevalence / (sensitivity x prevalence + (specificity 1) x (prevalence 1)). Nanostring Validation

[00258] Finally, 96 independent patient samples (i.e., those never profiled via microarray) from the Genomics of Pediatric SIRS and Septic Shiock Investigators tests18-22 were tested using a targeted digital multiplexed gene quantification assay, NanoString56. The 18 genes were not normalized back to any maintenance genes. The bacterial / viral SMS and metascore genes were tested, and the Petition 870260069557, dated 07 / 14 / 2026, p. 110 / 336 106 / 157 diagnostic performance of the IADM was calculated.

[00259] All analyses were performed in the R statistical computing language (version 3.1.1). The code to recreate the multicohort meta-analysis was previously deposited and is available at khatrilab.stanford.edu / sepsis. Table 1.
