AI Technical Summary
Current internal controls for sequencing-based microbial identification workflows do not effectively validate the performance of clinical sample processing, as they are not processed alongside the samples and thus cannot account for failures at each step of the workflow.
An internal process control (IPC) is introduced into clinical samples, processed alongside the microbial species, and used to control every step of the workflow. The IPC is a microbe that is lysed and its DNA is amplified and detected, indicating successful processing.
The use of IPCs ensures that the clinical sample processing workflow is validated, reducing the risk of false negatives and providing confidence in the accuracy of microbial identification.

[0001] INTERNAL PROCESS CONTROL
[0002] RELATED APPLICATIONS
[0003] This application claims priority to U.S. Provisional Application No. 63 / 605,451, filed December 1, 2023, the contents of which is herein incorporated by reference in its entirety.
[0004] BACKGROUND
[0005] Clinical samples are processed to identify microbes present in subjects (e.g., human subjects) from whom the clinical samples are obtained. Next-generation sequencing (NGS) has become a tool for microbial detection due to its potential for high throughput, high taxonomic resolution, and sensitivity. An NGS workflow typically contains numerous steps, and thus many opportunities for workflow failure.
[0006] SUMMARY
[0007] Rapid and accurate identification of microbes present in clinical samples from subjects is critical for detecting and treating microbial infections in a subject. With the decreasing costs of sequencing, next-generation sequencing (NGS)-based workflows have become a useful tool for microbial detection. Internal controls are essential for validating the performance of such a workflow.
[0008] Currently available internal controls for sequencing-based microbial identification workflows rely on the introduction of naked, synthetic, or artificially packaged nucleic acids, while others simply spike in a microbe after sample processing. Use of naked, synthetic, and artificially packaged nucleic acids does not control for clinical sample processing because these nucleic acids, which are not encompassed in microbial cells, are not affected by clinical sample processing in the manner that microbial cells are affected. Microbes spiked into samples after processing similarly do not control for clinical sample processing because they are not exposed to processing steps. Such solutions do not constitute true internal process controls and cannot account for failures at each step of the sample processing workflow.
[0009] Described herein is an internal process control (IPC) for use in clinical sample processing. Also provided herein are methods of detecting one or more microbial species in a clinical sample containing an IPC. Further provided herein are methods of determining whether a clinical sample comprises one or more microbial species. Additionally provided herein are methods of detecting one or more microbial species in a clinical sample. An IPC of the present disclosure is advantageous over simply spiking in a microbe or other controls (e.g., naked or artificially packaged nucleic acids) introduced before sequencing) because said IPCs are processed alongside the pathogen(s) inherent in the sample and / or the sample matrix and can be used as a control for every step of the workflow.
[0010] Detection of IPC nucleic acids at the end of clinical sample processing ensures that the processing was successful.

[0026] BRIEF DESCRIPTION OF DRAWINGS
[0027] The accompanying drawings are not intended to be drawn to scale. The drawings are illustrative only and are not required for enablement of the disclosure. For purposes of clarity, not every component may be labeled in every drawing. In the drawings:
[0028] FIG. 1 shows a heatmap of the pairwise genomic relatedness between 53 internal process control (IPC) candidate strains and a selection of 41 bacterial pathogens. Each row and column represent either an IPC candidate (numbers 1-53) or an exemplary bacterial pathogen (numbers 54-94). The percent similarity is represented by the average amino acid identity (AAI) score on the right.
[0029] FIG. 2 shows that an IPC does not interfere with target Pseudomonas aeruginosa (P. aeruginosa) signal in a whole blood sample. P aeruginosa and IPC cells (Leucobacter muris, L. muris) were recovered from blood samples, the bacterial cells were lysed, and bacterial whole genomes were amplified and sequenced. Total sequencing data (megabases) was mapped to P aeruginosa (black) or the IPC (gray). The sequencing reads for P aeruginosa or IPC were normalized to the total amount of sequencing data generated per sample. Concentrations of IPC added to the sample are represented on the x-axis (0-500 CFU / mL) and the ratio of megabases mapped to a target (P aeruginosa or the IPC) to the total number of sequenced megabases on the y-axis.
[0030] FIGs. 3A-3B show that IPC (Leucobacter muris, L. muris) signal recovery in samples spiked with clinically relevant pathogenic microbes is influenced by the guanine-cytosine (GC) content of the target pathogen. FIG. 3A shows pathogen genome recovery (% coverage, y-axis) in the presence (gray; “With IPC”) or absence (black; “No IPC”) of IPC in 10 mL blood samples spiked with 2 CFU / mL of 5 pathogens of increasing GC content (x- axis), with IPC spiked at 100 CFU / ml. No significant difference is observed in pathogen genome recovery between samples with and without the IPC for each of the 5 pathogens. FIG. 3B shows that recovery of the IPC genome (% coverage, y-axi content of target pathogen approaches that of the IPC, compared to low GC pathogens. GC content of species (low to high): Staphylococcus aureus (S. aureus) 32.8%; Candida albicans (C. albicans) 33.4%; Escherichia coli (E. coli) 50.8%; Klebsiella pneumoniae (K. pneumoniae) 57.0%, Pseudomonas aeruginosa (P. aeruginosa) 65.9%; and IPC 70.6%. This result demonstrates that the IPC did not interfere with recovery of pathogens across a wide range of GC content that captures substantially the GC content of all expected pathogen species in typical clinical samples.
[0031] DETAILED DESCRIPTION
[0032] Clinical samples are processed to identify microbes present in subjects (e.g., human subjects) from whom the clinical samples are obtained. Rapid, accurate identification of these microbes is critical for detecting and treating microbial infections in subjects. An internal control that can control the end-to-end processing is required for clinical sample processing to ensure that false negatives are minimized when identifying microbes.
[0033] The present disclosure provides an internal process control (IPC) for clinical sample processing and rapid, accurate identification of microbes in the clinical samples following whole genome amplification and microbial DNA sequencing. An IPC is added into a clinical sample before any processing steps have occurred so that it is processed alongside the one or more microbial species. Processing an IPC as part of a clinical sample allows the IPC to control for the steps of clinical sample processing. An IPC as provided herein is advantageous over simply spiking in a microbe or other controls such as naked or artificially packaged nucleic acids immediately before identification because the IPC is actually processed alongside the microbes endogenous to the sample. This IPC is a control microbe added at the beginning of clinical sample processing, is processed alongside any microbes in the clinical sample, and whose detection at the end of clinical sample processing indicates that the processing was successful. It is beneficial for an IPC to be phylogenetically divergent from microbes in the clinical sample, does not compete with the microbes for signal, and is devoid of small non-integrated self-replicating elements like plasmids.
[0034] The present disclosure therefore advances the field by providing an IPC to control for the steps of clinical sample processing and microbial identification. An IPC as described herein is advantageous because it can be used in clinical sample processing for next generation sequencing (NGS) and act as a control for every step of the workflow. Clinical Sample Processing
[0035] Methods provided herein include, in some embodiments, detecting one or more microbial species in a clinical sample. Such methods include, but are not limited to: (i) obtaining a clinical sample suspected of comprising one or more microbial species from a subject; (ii) introducing an internal process control (IPC) microbe into the clinical sample; (iii) processing the clinical sample with the IPC, including lysing the one or more microbial species and / or the IPC microbe; (iv) amplifying whole genome microbial DNA from the lysed microbial species and / or the lysed IPC microbe; and (v) detecting amplified microbial DNA and / or IPC DNA. The detection of IPC DNA at the end of the method indicates that processing the clinical sample was successful because the IPC was subjected to the same clinical processing steps as the one or more microbial species in a clinical sample. As used herein, suspected means that a clinical sample is from a subject that is thought to have a microbial infection or a subject who has been identified as likely to have a microbial infection. A clinical sample may be directly obtained from a subject as part of a method provided herein. A microbial infection may be with any microbe provided herein.
[0036] In some aspects, the present disclosure provides a method comprising: (i) obtaining a clinical sample suspected of comprising one or more microbial species from a subject; (ii) introducing one or more internal process control (IPC) microbes into the clinical sample; (iii) processing the clinical sample with the one or more IPC microbes, including lysing the one or more microbial species and / or the one or more IPC microbes; (iv) amplifying whole genome microbial DNA from the lysed microbial species and the lysed one or more IPC microbes; and (v) detecting amplified microbial DNA and / or IPC DNA, wherein the detection of IPC DNA in step (v) indicates that there was not a process failure.
[0037] In some aspects, the present disclosure provides a method comprising: (i) obtaining a clinical sample suspected of comprising one or more microbial species from a subject; (ii) introducing an internal process control (IPC) microbe into the clinical sample; (iii) processing the clinical sample to release whole genome microbial DNA from one or more microbes present in the sample including the IPC microbe including lysing the one or more microbial species and / or the IPC microbe; (iv) amplifying the released whole genome microbial DNA from the lysed microbial species and the lysed IPC microbe; and (v) detecting amplified microbial DNA and / or IPC DNA, wherein the detection of amplified IPC DNA in step (v) indicates that there was not a process failure, and wherein step (iii) optionally comprises lysing the one or more microbial species and / or the IPC microbes. In some aspects, the present disclosure provides a method co an internal process control (IPC) microbe into the clinical sample; (ii) processing the clinical sample with the IPC, including lysing the one or more microbial species and / or the IPC microbe; (iii) amplifying whole genome microbial DNA from the lysed microbial species and / or the lysed IPC microbe; and (iv) detecting amplified microbial DNA and / or IPC DNA, wherein the detection of IPC DNA in step (iv) indicates that there was not a process failure.
[0038] Microbial Species
[0039] Methods provided herein include detecting one or more microbial species in a clinical sample. The term “microbial species”, as used herein, is any microorganism that is present in a clinical sample. In some embodiments, the microbial species is a bacterium, a virus, a fungus, a parasite, or any combination thereof. The microbial species present in a sample may be a commensal organism, which is a microorganism (e.g., bacteria, virus, fungus, or parasite) that lives in or on a subject without causing harm to the host or providing any significant benefits, or may be a pathogenic organism, which is a microorganism (e.g., bacteria, virus, fungus, mold, or parasite) that has disease-causing potential. The terms “pathogenic organism” or “pathogenic microbial species”, are used interchangeably herein and refer to a microorganism (e.g., bacteria, virus, fungus, or parasite), that has the ability to cause disease in a subject by invading, colonizing, and / or multiplying within the subject, leading to various illnesses or infections. In some embodiments, a commensal organism can turn into a pathogenic organism in a process referred to as “commensal-to-pathogen transition”. Non-limiting factors contributing to this shift include: i) genetic mutations that may result in the acquisition of new genes or the loss of gene that regulate virulence, increasing the organism’s pathogenic potential; ii) horizontal gene transfer, in which a commensal organism acquires virulence factors or antibiotic resistance genes from another microorganism; iii) changes in environmental conditions, such as antibiotic use or immune system suppression; and, iv) microbiota dysbiosis, in which alterations in a host’s microbiome composition and diversity creates opportunities for commensal organisms to compete with or displace other microorganisms.
[0040] In some embodiments, one or more microbial species in a clinical sample provided herein is a pathogenic microbial species. One microbial species or multiple microbial species in a clinical sample may be pathogenic. In some embodiments, 1, 2, 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 or more microbial species are pathogenic microbial species. In some embodiments, the one or more microbial species comprise 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 11
[0041] 24, 25, 26, 27, 28, 29, or 30 or more microbial species. In some embodiments, the one or more microbial species comprise commensal microbial species and / or pathogenic microbial species.
[0042] In some embodiments, a pathogenic microbial species is a bacterium. A bacterium is a prokaryote that lacks a true cell nucleus and membrane-bound organelles.

[0046] In some embodiments, a pathogenic microbial species is a virus. A virus is a microscopic infectious agent that contains genetic material (e.g., DNA or RNA) and a protein coat (e.g., capsid). In some embodiments, the virus is an RNA virus or a DNA virus. An RNA virus contains RNA as its genetic material, and a DNA virus contains DNA as its genetic material. In some embodiments where a genetic material is RNA, a method provided herein comprises a reverse transcription step. Reverse transcription is synthesis of a new DNA molecule by the enzyme reverse transcriptase.
[0047] In embodiments of the present disclosure where a pathogenic microbial species is a virus, a method provided herein comprises lysing the virus. Lysing the virus may be by any method known in the art including, but not limited to: chemical lysis (e.g., sodium dodecyl sulfate (SDS) treatment, EDTA treatment, surfactant treatment), temperature lysis (e.g., repeated freeze / thaw cycles), mechanical lysis (e.g., homogenizer, bead beating), or some combination thereof.
[0048] In some embodiments, the RNA virus is a single-stranded RNA virus or a doublestranded RNA virus. In some embodiments, the single-stranded RNA virus is a singlestranded positive-sense RNA virus that can be immediately translated into protein by a host cell (e.g., a cell in a subject). In some embodiments, the single-stranded RNA virus is a single-stranded negative-sense RNA virus that must be converted to positive-sense RNA prior to being translated into protein by a host cell (e.g., a cell in a subject). In some embodiments, the DNA virus is a single-stranded DNA virus, a partially double-stranded DNA virus, or a double-stranded DNA virus.

[0054] In some embodiments, a pathogenic microbial species is a parasite. In some embodiments, a parasite is a protozoan, a helminth, or an arthropod. Protozoa are singlecelled eukaryotic microorganisms belonging to the Kingdom Protist. Helminths are a group of parasitic, multicellular, eukaryotic worms that can be classified into three main groups based on their morphology: 1) trematodes (flukes), which are flatworms that commonly infect the internal organs of their host; 2) cestodes (tapeworms), whi host’s intestine; and, 3) nematodes (roundworms), which can infect various body tissues including the digestive tract, respiratory system, and muscles. Arthropods are invertebrate animals that can transmit disease-causing pathogens (e.g., bacteria, viruses, protozoa, or helminths) to humans and other animals.

[0057] Internal Process Control (IPC)
[0058] In some embodiments, a method provided herein comprises introducing an internal process control (IPC) microbe into a clinical sample suspected of comprising one or more microbial species. An “internal process control (IPC) microbe”, as used herein, is a known control microbe. The IPC microbe may be a microbial species that is not expected to be present in the clinical sample. The IPC microbe may be a well-characterized microbe. IPCs of the present disclosure can be added to a sample at a known concentration prior to clinical sample processing and processed alongside inherent clinical sample microbes in a clinical sample processing workflow.
[0059] As used herein, “end” of a clinical sample processing workflow refers to the last step of a clinical sample processing workflow having been accomplished. In some embodiments, the last step of a clinical sample processing workflow is detection of microbial DNA and / or IPC DNA. In some embodiments, the last step of a clinical sample processing workflow is detection of amplified microbial DNA and / or amplified IPC DNA. In some embodiments, the last step of a clinical sample processing workflow is sequencing of microbial DNA and / or IPC DNA. In some embodiments, the last step of a clinical sample processing workflow is sequencing of amplified microbial DNA and / or amplified IPC DNA. In some embodiments, the last step of a clinical sample processing workflow is quantifying microbial DNA and / or IPC DNA. In some embodiments, the last step of a clinical sample processing workflow is quantifying amplified microbial DNA and / or amplified IPC DNA.
[0060] The detection of the IPC following the clinical sample processing workflow ensures that the processing was successful. In some embodiments, the detection of IPC DNA at the end of the clinical sample processing workflow indicates that the processing was successful. In some embodiments, the detection of IPC DNA at the end of a clinical sample processing workflow validates a negative result (e.g., the detection of zero microbial species in the clinical sample).
[0061] In some embodiments, the detection of IPC DNA in a clinical sample processing indicates that there was not a process failure. A process failure, as used herein, refers to some malfunction of a sample processing workflow, which could occur at processing workflow. A failure in the processing steps might mean that one or more of the processing steps are not successful and the genome of the one or more microbial species suspected of being in the clinical sample is not able to be amplified and thus detected.
[0062] In some embodiments, an IPC microbe is a bacterium. A bacterium is a single-celled microorganism that belongs to the domain Bacteria. They are prokaryotic organisms, meaning that they lack a cell nucleus and other membrane-bound organelles found in eukaryotic cells. In some embodiments, the IPC microbe is a Gram-positive bacterium. A gram-positive bacterium has a thick peptidoglycan cell wall that retains the crystal violet stain used in the Gram staining process and has no outer membrane.

[0069] In some embodiments, the IPC microbe has a guanine / cytosine (GC) content that is higher than the one or more microbial species expected to be present in the sample. GC content is a measure of the proportion of guanine and cytosine bases in a DNA or RNA molecule, such as in a genome. In some embodiments, the IPC microbe has at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, or at least 95% GC content in its genome. In some emboc has between 50-55%, 55-60%, 60-65%, 65-70%, 70-75%, 75-80%, 80-85%, 85-90%, 90- 95%, or 95-100% GC content in its genome. In some embodiments, the IPC microbe has between 50-100%, 50-95%, 55-95%, 55-90%, 60-90%, 60-85%, 65-80%, or 70-80% GC content in its genome. In some embodiments, the IPC microbe has 55% - 90% GC content in its genome.
[0070] In some embodiments, the IPC microbe is devoid of non-integrated self-replicating genetic elements (e.g., plasmids). In some embodiments, the IPC microbe is devoid of mobile genetic elements. The term “devoid”, as used herein, refers to having less than 50% mobile genetic element content and / or having less than 50% non-integrated self-replicating genetic elements in a genome. In some embodiments, an IPC microbe has 0%, less than 5%, less than 10%, less than 15%, less than 20%, less than 25%, less than 30%, less than 35%, less than 40%, less than 45%, or less than 50% non-integrated self-replication genetic elements in its genome. In some embodiments, an IPC microbe has 0-5%, 5-10%, 10-15%, 15-20%, 20- 25%, 25-30%, 30-35%, 35-40%, 40-45%, or 45-50% non-integrated self-replication genetic elements in its genome. In some embodiments, an IPC microbe has less 10% non-integrated self-replication genetic elements in its genome. In some embodiments, an IPC microbe has less 5% non-integrated self-replication genetic elements in its genome. In some embodiments, an IPC microbe has between 0-50%, 0-45%, 5-45%, 5-40%, 10-40%, 10-35%, 15-35%, 15-30%, or 20-25% non-integrated self-replication genetic elements in its genome.

[0086] Detecting
[0087] Methods provided herein include detecting one or more microbial species inherent in a clinical sample. The term “detecting”, as used herein, refers to the process of identifying and / or confirming the presence of one or more microbial species (e.g., bacteria, virus, fungus, or parasite) inherent in a sample (e.g., clinical sample). Those skilled in the art will recognize that such techniques for detecting microbial species from a sample (e.g., a clinical sample) may require one or more processing steps.
[0088] As used herein, “processing” or “processed” refers to preparing (e.g., cell lysis, DNA amplification) a clinical sample for analysis (e.g., sequencing). In some embodiments, processing may include centrifugation (e.g., velocity sedimentation), separating supernatant (e.g., from a pellet) and moving the supernatant to a separate tube (e.g., from the pellet), cell lysis (e.g., host cell lysis, microbial cell lysis, IPC cell lysis), microbial enrichment (e.g., by filtration, centrifugation, or molecular techniques, such as polymerase chain reaction (PCR)), nucleic acid (e.g., DNA or RNA) isolation, or any combination thereof.
[0089] In some embodiments, processing may include one or more centrifugation steps, such as velocity sedimentation. Velocity sedimentation, also known as rate-zonal centrifugation, is a technique used to separate particles in a solution based on their size and shape, where larger molecules accumulate in a pellet at the bottom of the container (e.g., tube) being centrifuged and smaller molecules accumulate in the supernatant above the pellet. This method can be employed to fractionate macromolecules (e.g., proteins, nucleic acids, or subcellular organelles) according to their sedimentation rates in a centrifugal field. In the present disclosure, centrifugation may be used to pellet larger human cells so that smaller microbial cells (and cellular debris) can be separated from the larger human cells. In some embodiments, processing may include separating a s pellet). Separating a supernatant typically involves the separation of a liquid (the supernatant containing one or more microbial species) from solid particles (e.g., the pellet containing human cells and macromolecular aggregates) that have settled at the bottom of a container. The supernatant can be separated by decanting the supernatant into a new container or by pipetting (e.g., using a Pasteur pipette or a micropipette).
[0090] In some embodiments, a supernatant from velocity sedimentation is used for further clinical sample processing.
[0091] In some embodiments, processing may include cell lysis or virus lysis. Cell lysis is the process of breaking open or rupturing cell membranes and / or nuclear membranes to release their contents (e.g., organelles, proteins, DNA, and RNA). Virus lysis is the process of breaking open or rupturing virus particles, virus envelopes, and / or viral capsids to release viral contents (e.g., proteins, DNA, RNA). In some embodiments, the cell lysis is host (e.g., human) cell lysis. In some embodiments, the cell lysis is microbial (e.g., bacteria, fungus, or a parasite) cell lysis. In some embodiments, the cell lysis is internal process control (IPC) lysis. In some embodiments, the host (e.g., human) and microbial (e.g., bacteria, fungus, or a parasite) cells or virus can be differentially lysed and fractionated based on their specific properties, such as size, density, or other chemical properties, including cell membrane, cell wall composition, viral envelope composition, and / or viral capsid. There are several methods for performing cell lysis and virus known in the art, such as mechanical lysis (e.g., homogenization, bead beating), chemical lysis (e.g., detergent lysis, such as with Triton X- 100 or sodium dodecyl sulfate (SDS)), enzymatic lysis (e.g., using lysozyme), freeze-thaw lysis, ultrasonication, high-pressure homogenization, osmotic shock, or electroporation.
[0092] In some embodiments, processing may include microbial enrichment (e.g., by filtration, centrifugation, or molecular techniques, such as polymerase chain reaction (PCR)). Enriching for microbes involves increasing the relative abundance of the target microbial species (e.g., bacteria, virus, fungus, or parasite) so that they can be more easily detected and identified. Relative abundance may be relative to the original clinical sample or relative to non-microbial cells. In some embodiments, microbial enrichment may be performed using filtration, whereby a sample is passed through a filter with a specific pore size that retains the microbial species (e.g., bacteria, virus, fungus, or parasite) while allowing other materials to pass through. In some embodiments, microbial enrichment may be performed using centrifugation, such as ultracentrifugation. In some embodiments, microbial enrichment may be performed using molecular techniques such as polymerase chain reaction (PCR), which can selectively amplify the DNA or RNA of the microbial species in embodiments, microbial enrichment may be performed using a combination of filtration, centrifugation, and / or molecular techniques.
[0093] In some embodiments, processing may include nucleic acid (e.g., DNA or RNA) isolation. Nucleic acid isolation (also known as nucleic acid extraction) is a technique used to obtain DNA or RNA from a biological sample. The DNA or RNA that is isolated can be derived from the host (e.g., human) or from microbial species (e.g., bacteria, virus, fungi, or parasites). Methods of performing nucleic acid isolation are known to those of skill in the art and can include, but are not limited to, phenol-chloroform extraction, silica-based spin columns, magnetic bead-based purification, organic solvent precipitation, solid-phase extraction, or ultracentrifugation.
[0094] In some embodiments, a method for detecting one or more microbial species in a clinical sample comprises processing a clinical sample with an IPC, including lysing the one or more microbial species and / or the IPC microbe.
[0095] In some embodiments, processing may include amplifying genome microbial DNA from lysed microbial species and lysed IPC microbe. In some embodiments, the microbial DNA is whole genome microbial DNA. In some embodiments, the microbial DNA (e.g., whole genome microbial DNA) is from a lysed microbial species and a lysed IPC microbe. Non-limiting examples of methods for amplifying microbial DNA include genome amplification (GA), polymerase chain reaction (PCR), quantitative PCR (qPCR), loop- mediated isothermal amplification (LAMP), whole genome amplification (WGA), multiple displacement amplification (MDA), strand displacement amplification (SDA), random amplification of polymorphic DNA (RAPD), restriction fragment length polymorphism (RFLP), and rolling circle amplification (RCA). In some embodiments, whole genome microbial DNA from lysed microbial species and lysed IPC microbe is amplified using MDA.
[0096] Genome amplification may be whole genome amplification (100% of the microbial genome, the IPC genome). Genome amplification may be greater than 1% of the microbial genome, greater than 5% of the microbial genome, greater than 10% of the microbial genome, greater than 15% of the microbial genome, greater than 20% of the microbial genome, greater than 25% of the microbial genome, greater than 30% of the microbial genome, greater than 35% of the microbial genome, greater than 40% of the microbial genome, greater than 45% of the microbial genome, greater than 50% of the microbial genome, greater than 55% of the microbial genome, greater than 60% of the microbial genome, greater than 65% of the microbial genome, greater than 70% of the microbial genome, greater than 75% of the microbial genome, greater than 80° genome, greater than 85% of the microbial genome, greater than 90% of the microbial genome, greater than 95% of the microbial genome, or greater than 99% of the microbial genome. Genome amplification may be greater than 1% of the IPC genome, greater than 5% of the IPC genome, greater than 10% of the IPC genome, greater than 15% of the IPC genome, greater than 20% of the IPC genome, greater than 25% of the IPC genome, greater than 30% of the IPC genome, greater than 35% of the IPC genome, greater than 40% of the IPC genome, greater than 45% of the IPC genome, greater than 50% of the IPC genome, greater than 55% of the IPC genome, greater than 60% of the IPC genome, greater than 65% of the IPC genome, greater than 70% of the IPC genome, greater than 75% of the IPC genome, greater than 80% of the IPC genome, greater than 85% of the IPC genome, greater than 90% of the IPC genome, greater than 95% of the IPC genome, or greater than 99% of the IPC genome. In some embodiments, processing may include amplifying microbial DNA from microbial species and IPC microbe. In some embodiments, processing may include amplifying whole genome microbial DNA from lysed microbial species and lysed IPC microbe.
[0097] In some embodiments, processing may include detecting amplified microbial DNA and IPC DNA. The detected DNA may be amplified (e.g., having undergone DNA amplification) or not amplified. Amplified DNA may be amplified by any process described herein.
[0098] In some embodiments, amplified DNA (e.g., microbial DNA and IPC DNA) is detected. As used herein, detection of amplified DNA (e.g., microbial DNA and IPC DNA) refers to the identification and confirmation of the presence of specific DNA sequences (occurring in a specific microbe or IPC microbe) in a sample following DNA amplification. The detection can be qualitative, to confirm the presence or absence of the target DNA sequence, or quantitative, to provide information about the amount or concentration of the amplified DNA. Methods of detecting amplified DNA (e.g., microbial DNA and IPC DNA) include, but are not limited to, next-generation sequencing (e.g., Illumina sequencing or nanopore sequencing), agarose gel electrophoresis, polyacrylamide gel electrophoresis, ethidium bromide staining, SYBR green staining, fluorescent probes (e.g., TaqMan probes, molecular beacons, dual-labeled probes), DNA intercalating dyes (e.g., EvaGreen or SYBR Safe), DNA fragment analysis (e.g., capillary electrophoresis), real-time PCR (qPCR), digital PCR, nucleic acid hybridization (e.g., microarrays), enzyme-linked immunosorbent assays (ELISA), or microscopy. In some embodiments, one or more microbial species inhere) detected using sequencing (e.g., next-generation sequencing (NGS)). Sequencing data from clinical samples is analyzed to measure the breadth of coverage of a microbial species genome within the sequencing data. This approach is particularly advantageous in sequencing data obtained from clinical samples, which may include human DNA and other confounding DNA sources in addition to DNA from one or more microbial species. By measuring the breadth of coverage of a microbial species genome, contaminating DNA (e.g., human DNA, confounding DNA) may be removed from microbial DNA for processing. In some embodiments, only microbial species with a 0.5x - lOx microbial genome coverage are identified in the present disclosure. In some embodiments, only microbial species with a 0.5x, 0.6x, 0.7x, 0.8x, 0.9x, l.Ox, l.lx, 1.2x, 1.3x, 1.4x, 1.5x, 1.6x, 1.7x, 1.8x, 1.9x, 2. Ox, 2. lx,

[0104] Sequencing reads following processing of a clinical sample are aligned to reference genomes from one or more microbial species. This alignment may be performed manually or by using an open-source software tool (e.g., bwa-mem, rhat, GraphMap, minimap2). The breadth of coverage of a microbial species may be calculated by simply counting sequencing reads for each microbial species or by reconstructing the whole genome of the one or more microbial species from sequencing reads in the clinical sample. Reconstructing the whole genome of one or more microbial species may be performed using an open-source software tool (e.g., / / )'c, Canu, Raven, Shasta, Miniasm) or manually. Once a whole genome of one or more microbial species is reconstructed, the one or more microbial species may be identified using an open-source software tool (e.g., Krakeri) or manually.

[0108] Process failure
[0109] The term “process failure”, as used herein, refers to failure at one or more steps in the sample processing workflow. In some embodiments, failure occurs during a lysis step (e.g., host cell lysis or microbial lysis). Failure during a lysis step can occur for a variety of reasons, including application of improper lysis buffers or buffer conditions, inadequate mechanical disruption methods, or insufficient incubation times. In some embodiments, failure occurs during an amplification step (e.g., microbial genome amplification). Nonlimiting reasons for failure during an amplification step include poor DNA quality, the presence of inhibitors or contaminants that interfere with the amplification process, suboptimal reaction conditions (e.g., improper primer design or reaction conditions, such as temperature and / or time), low template DNA concentrations, or the presence of highly repetitive DNA regions. In some embodiments, failure occurs during the detection step (e.g., sequencing). In some embodiments, failure occurs during sequencing. Sequencing failure may be due to low DNA quality, issues with library preparation, instrumentation issues, insufficient read depth, low signal quality, or poor cluster generation. In some embodiments, a process failure means that a test result is invalid.

[0128] Methods of Use
[0129] An internal process control (IPC) may be used in any clinical sample processing protocol that employs molecular techniques to detect one or more microbial species suspected of being in a clinical sample provided herein. Non-limiting examples of molecular techniques that may utilize an IPC include: detecting one or more microbial species, quantifying one or more microbial species, and predicting appropriate treatment for infection with one or more microbial species.
[0130] An IPC may be used in detecting one or more microbial species suspected of being within a clinical sample. Detecting one or more microbial species may be by any process provided herein. In some embodiments, an IPC is introduced into a clinical sample after obtaining the clinical sample from a subject (e.g., a human subject), processed as part of the clinical sample, has its genome amplified alongside one or more mic of being in the clinical sample, after which it is detected.
[0131] An IPC may be used in quantifying one or more microbial species suspected of being in a clinical sample. Quantifying one or more microbial species requires identifying the one or more microbial species that is to be quantified. Identifying the one or more microbial species to be quantified may be by any method provided herein. One or more microbial species to be quantified may be amplified (e.g., by any method provided herein) or may not be amplified. Quantification may be by any method known in the art. Non-limiting examples of quantifying one or more microbial species in a clinical sample include: measuring microbial genome coverage, measuring the number of times a target sequence (e.g., in a microbial genome) appears in a sample, and measuring colony forming units (CFUs). In some embodiments, microbial genome coverage is measured to quantify one or more microbial species suspected of being in a clinical sample. Measuring microbial genome coverage may be by any method provided herein (e.g., manually, using open-source software tools). Quantification of one or more microbial species (e.g., in a clinical sample) may be expressed as a total number (e.g., total number of microbial cells, genomes, total number of CFUs) or as a relative number. If the quantification of one or more microbial species is expressed as a relative number, it may be relative to human or microbe (e.g., human cells, microbial cells, human DNA reads, microbial DNA reads).
[0132] In some embodiments, an IPC may be used to quantify one or more microbial species in a clinical sample. By adding a known concentration of IPC (CFU / mL) added to a clinical sample, it would allow quantification of other microbes by any method provided herein.
[0133] An IPC may be used in clinical sample processing for predicting appropriate treatment for infection with one or more microbial species suspected of being in a clinical sample. A microbe may be susceptible to a potential treatment, resistant to a potential treatment, or neither susceptible nor resistant to a potential treatment. A microbe is susceptible to a potential treatment if contacting the microbe (e.g., in a human subject) with the potential treatment causes reduced survival of the microbe, reduced proliferation of the microbe, or some combination thereof. A microbe is resistant to a potential treatment if contacting the microbe with the potential treatment does not cause reduced survival of the microbe, reduced proliferation of the microbe, or some combination thereof. A microbe may be susceptible to a potential treatment under certain circumstances (e.g., environmental conditions, co-infections with other microbes, etc.) and resistant to the same potential treatment under other circumstances. Predicting appropriate treatment for infection requires identii microbial species, which may be accomplished by any method provided herein. Appropriate treatment may be predicted by any method known in the art. Non-limiting methods of predicting appropriate treatment include: utilizing sequencing data and testing antimicrobial agents that the one or more microbial species are known to be susceptible to. In some embodiments, methods of predicting appropriate antimicrobial treatment include utilizing sequencing data. Sequencing data may be whole genome sequencing data or partial genome sequencing data. When whole genome sequencing data is used to predict appropriate antimicrobial treatment, the genome sequences for a microbe may be compared against a reference database of sequences known to confer antimicrobial agent resistance or susceptibility. Non-limiting examples of reference databases include: Comprehensive Antibiotic Resistance Database (CARD), National Database of Antibiotic Resistant Organisms (NARDO), AMRFinder Plus, ResFinder, ResFinder Plus, and Resistance Map.
[0134] For example, when whole genome sequencing data is used to predict appropriate antimicrobial treatment in Staphylococcus aureus (S. aureus), the whole genome sequencing data may be compared to sequences known to confer resistance to antibiotics such as vancomycin, methicillin, or any other antibiotic used to treat S. aureus infection. Alternatively, whole genome sequencing data may be used to create a de novo reference database that draws on known antimicrobial susceptibility or resistance sequences.
[0135] An antimicrobial agent may be an antibacterial agent, an antifungal agent, an antiviral agent, an anti-parasitic agent, or a combination thereof. Non-limiting examples of antimicrobial agents include: penicillin, methicillin, oxacillin, ampicillin, piperacillin, amoxicillin, cephazolin, cephalexin, cefuroxime, cefoxitin, cefotaxime, ceftriaxone, cefepime, vancomycin, teicoplanin, bleomycin, imipenem, meropenem, gentamicin, tobramycin, amikacin, erythromycin, clarithromycin, azithromycin, tetracycline, doxycycline, chloramphenicol, clindamycin, sulfisoxazole, sulfamethoxazole, metronidazole, trimethoprim, rifampicin, quinolones, clotrimazole, econazole, miconazole, terbinafine, fluconazole, ketoconazole, nystatin, amphotericin, candicidin, fllipin, hamycin, natamycin, rimocidin, bifonazole, butoconazole, econazole, fenticonazole, isoconazole, luliconazole, omoconazole, oxiconazole, sertaconazole, sulconazole, tioconazole, albaconazole, efinaconazole, epoxiconazole, isavuconazole, itraconazole, osaconazole, propi conazole, ravuconazole, terconazole, voriconazole, abafungin, anidulafungin, caspfungin, micafungin, ibrexafungerp, acrisorcin, amorolfme, aurones, benzoic acid, abacavir, acyclovir, adefovir, amantadine, ampligen, amprenavir, umifenovir, atazanavir, tenofovir, baloxavir marboxil, boceprevir, bulevirtide, cidofovir, cobicistat, combivir, daclatasvir, d delaviridine, didanosine, docosanol, dolutegravir, doravirine, edoxudine, efavirenz, elvitegravir, emtricitabine, enfuvirtide, ensitrelvir, entecavir, etravirine, famciclovir, fomivirsen, fosamprenavir, foscarnet, ganciclovir, ibacitabine, ibalizumab, idoxuridine, imiquimoid, inosine pranobex, idinavir, lamivudine, letermovir, lopinavir, loviride, maraviroc, methisazone, moroxydine, nelfinavir, nevirapine, nitazoxanide, norvir, oseltamivir, penciclovir, peramivir, pleconaril, podophyllotoxin, raltegravir, remdesivir, ribavirin, rilpivirine, rimantadine, ritonavir, saquinavir, simeprevir, sofosbuvir, stavudine, taribavirin, telaprevir, telbivudine, tenofovir alafenamide, tenofovir disoproxil, tipranavir, trifluridine, trizivir, tromantadine, Truvada, umifenovir, valaciclovir, valganciclovir, vicriviroc, vidarabine, zalcitabine, zanamivir, zidovudine, ivermectin, pyrimethamine, dapsone, mefloquine, sulfadiazine, quinine, nitazoxanide, albendazole, piperazine, amodiaquine, furazolidone, mebendazole, sulfametopyrazine, diethylcarbamazine, thiabendazole, pentamidine, levamisole, tinidazole, praziquantel, primaquine, oxamniquine, atovaquone, proguanil, halofantrine, poscaconazole, sulfadoxine, paromomycin, hydroxychloroquine, sinefungin 5-S-methyl-5’-thioadenosine, fumagillin, benzimidazole, diminazene, radicicol, geneticin, halofuginone, oxibendazole, lucanthone, andrographolide, spiramycin, eflornithine, lonidamine, tafenoquine, niclosamide, anisomycin, chlortetracycline, artesunate, pyrantel, hexylresorcinol, dichlorvos, doramectin, moxidectin, phenothiazine, selamectin, salinomycin, artenimol, nifurtimox, triclabendazole, secnidazole, carbendazim, piperaquine, chloroquine, quinacrine, suramin, sodium stibogluconate, artemether, hycanthone, tetrandrine, and lotilaner.
[0136] Without further elaboration, it is believed that one skilled in the art can, based on the above description, utilize the present invention to its fullest extent. The following specific embodiments are, therefore, to be construed as merely illustrative, and not limitative of the reminder of the disclosure in any way whatsoever.
[0137] EXAMPLES
[0138] Example 1. Internal Process Control Strain Selection
[0139] Molecular diagnostic tests typically employ spiked-in controls that are co-extracted and co-amplified in nucleic acid test-based detection methods. However, in next generation sequencing-based sample-to-answer diagnostic assays, internal process controls (IPCs) are useful to control every step of the diagnostic workflow. In applicatic time is limited, the IPC sequences could have a very high probability to out-compete target sequences at limit of detection concentrations, especially in the presence of other host- derived background nucleic acids. To address this issue and to improve assay specificity, an Internal Process Control (IPC) was developed to differentiate a negative result from a process failure within a sequencing assay without outcompeting target pathogen sequences (Table 1). If a target pathogen is identified in a clinical sample, the target is interpreted as being in the sample. If a target pathogen is not identified in a clinical sample that contains an IPC and the IPC is identified, the target is interpreted as being absent from the sample. If a target pathogen is not identified in a clinical sample and the IPC is not identified, the output is interpreted as a process failure.
[0140] Table 1. Interpreting sequencing assay output using an IPC in a clinical sample.
[0141] A useful IPC possesses particular characteristics. Candidate IPCs were selected in methods of the present disclosure are based on the following criteria:
[0142] • Ability to control for performance (e.g., sensitivity, specificity, accuracy, precision) in an end-to-end process;
[0143] • Having similar behavior to an analyte (e.g., a bacterial or fungal IPC for detecting bacterial or fungal pathogens) during processing;
[0144] • Phylogenetically divergent from analytes (e.g., distinct from pathogens);
[0145] • Having minimal interference or competition with an analyte signal (e.g., does not represent the majority of the sequencing reads);
[0146] • Having process bias (e.g., having high GC content); and
[0147] • Devoid of mobile genetic elements or plasmids that could over-amplify, creating competition with analytes, or be misidentified as belonging to inherent microbes in a clinical sample. A panel of candidate IPCs were analyzed and evaluated for their performance in a clinical sample processing end-to-end process. Candidate IPCs (e.g., Leucobacter muris, Leucobacter triazinivorans, Cellulomans iranesis, and Serinicoccus chugangensis) were spiked-in at a known concentration to a blood sample. This sample was then processed according to a whole blood lysis workflow. Briefly, this workflow includes the following steps: host cell lysis, microbial lysis, microbial genome amplification, sequencing, and bioinformatic analyses.
[0148] The species identified in each sample were evaluated for relatedness using prokaryotic sequence average amino acid identity (AAI) and visualized using hierarchical clustering (FIG. 1). Each of the IPCs scored similarly across all samples, with low AAI values, and demonstrated no significant relatedness between the IPCs and representative bacterial pathogens.
[0149] The results of this study indicate that incorporation of an IPC into an end-to-end process can enable the differentiation of false-negative results due to process failures mediated by the system, reagents, or sample, which are characterized by an absence of an IPC signal, from true negative results, which are characterized by the presence of an IPC signal.
[0150] Example 2. Successful IPC Detection With Target Pathogen in Clinical Samples
[0151] Presence of IPC (Leucobacter muris, L. muris) does not interfere with the target pathogen signal. Increasing concentrations of the IPC (0-500 CFU / ml) were added to 10 ml blood samples spiked in with the pathogen Pseudomonas aeruginosa (P. aeruginosa) at 8 CFU / mL. Pathogen and IPC cells were recovered from blood samples, pathogen and IPC cells were lysed, and pathogen and IPC whole genomes were amplified and sequenced on a nanopore sequencer (Oxford Nanopore PromethlON 2 flow cells) using the RBK114 library preparation kit. Total sequencing data (megabases) mapped to P aeruginosa (black) or the IPC (gray) was normalized to the total amount of sequencing data generated per sample with no significant difference observed for P. aeruginosa sequencing yield between samples with different concentrations of the IPC (FIG. 2). Concentrations of IPC added to the sample are represented on the x-axis (0-500 CFU / mL) with the ratio of megabases mapped to a target (P aeruginosa or the IPC) to the total number of sequenced megabases on the y-axis.
[0152] IPC signal recovery in samples spiked with clinically relevant pathogenic microbes is influenced by the guanine: cytosine (GC) content of the target pathogen. Percentages of total genomes at >lx depth recovered for pathogens (FIG. 3 A) and IPC (.
[0153] (FIG. 3B) from the spiked in blood samples following microbial recovery, whole genome amplification and sequencing is shown. Genome recovery (% coverage, y-axis) in the presence (gray) or absence of IPC (black) in 10 ml blood samples spiked with 2 CFU / mL of 5 pathogens of increasing GC content (x-axis), with IPC spiked at 100 CFU / ml. (FIG. 3A) No significant difference is observed in pathogen genome recovery between samples with and without the IPC for each of the 5 pathogens. Recovery of the IPC genome (% coverage, x- axis) increases as the GC content of target pathogen approaches that of the IPC, compared to low GC pathogens. GC content of species (low to high): Staphylococcus aureus (S. aureus) 32.8%; Candida albicans (C. albicans) 33.4%; Escherichia coli (E. coll) 50.8%; Klebsiella pneumoniae (K. pneumoniae) 57.0%, Pseudomonas aeruginosa (P. aeruginosa) 65.9%; IPC 70.6% (FIG. 3B).
