Description
[0001] Sequence Listing
[0002] This application contains a Sequence Listing according to 37 CFR 1.821-1.825. The Sequence Listing accompanying this application is incorporated herein by reference in its entirety. Background of the Invention
[0004] Avian coronavirus infectious bronchitis virus (IBV) is a prototype gamma coronavirus of the family Coronaviridae of the order Nidovirales. Infectious bronchitis virus primarily infects the upper respiratory epithelium of chickens, causing respiratory disease, often complicated by secondary bacterial pathogen infection (Cook et al. 2012. Avian Pathol. 41: 239-250). Some IBV strains also affect the renal tubules, oviducts, and parts of the gastrointestinal tract, causing pathological lesions and clinical signs in these organ systems. The virus is widely present in commercial poultry and backyard poultry. Due to its high genomic variability, IBV is divided into multiple genotypes, serotypes, and protective types. IBV is currently considered to be one of the most economically relevant viral pathogens in the poultry industry.
[0005] Infectious bronchitis virus is an enveloped virus with a 27.6kb positive single-stranded RNA genome (Cavanagh 2007.Vet.Res.38:281-297). The first two-thirds of the viral genome contains a large coding region (also called gene 1), divided into two open reading frames 1a and 1b, which encode 15 non-structural proteins involved in RNA replication, editing and transcription. The last third of the viral genome encodes structural proteins: spike protein (S, encoded by gene 2), envelope protein (E, encoded by gene 3c), membrane protein (M, encoded by gene 4), nucleocapsid protein (N, encoded by gene 6). Proteins S, E and M are part of the viral envelope, while protein N forms the ribonucleoprotein core together with viral RNA. The coronavirus spike protein determines the host species tropism (Kuo et al.2000.J.Virol.74:1393-1406). It is a dimeric or trimeric transmembrane protein that is proteolytically broken down into two subunits, S1 and S2. The highly glycosylated S1 domain forms the "head" of the spike protein and contains a receptor binding domain that interacts with 2,3-linked sialic acids on the surface of the host cell (Promkuntod et al. 2014. Virology. 448: 26-32). The S2 domain contains the rest of the extracellular domain (ectodomain) (the "stem"), the transmembrane domain, and the intracellular domain located in the cytoplasm.
[0006] To date, the most widely used live attenuated IBV vaccine strain was developed in the Netherlands in the 1960s by serial passage of a Massachusetts-like IBV strain (Bijlenga et al. 2004; Avian Pathol. 33:550-557). However, since the 1970s, new IBV serotypes have emerged for which traditional Massachusetts-like vaccines do not provide adequate protection (Cook et al. 2012. Avian Pathol. 41:239-250). Therefore, there is still a need for new and highly effective IBV vaccines against other IBV serotypes.
[0007] IBV Beaudette (Geilhausen et al. 1973. Arch Gesamte Virusforsch.: 40(3) (1973), pp. 285-290) and H120 (G. Bijlenga et al. 2004. Avian Pathol.: 33(6); pp. 550-557) are attenuated IBVs. However, attenuation may result in loss of immunogenicity.
[0008] In addition, recombinant IBV has been generated. Zhou et al. 2016 (Arch Virol.; 161:3179-3187) disclosed an H120 (Massachusetts genotype) IBV with a Beaudette (Massachusetts genotype) spike protein. Hodgson et al. 2004 (J Virol 78:13804-13811) disclosed a Beaudette (Massachusetts genotype) IBV with an M41 (Massachusetts genotype) spike protein. In addition, Armesto et al. 2011 (PLoS One: 6(8):e24352) disclosed an IBV Beaudette (Massachusetts genotype) with a heterologous spike protein from 4 / 91 (4 / 91 genotype).
[0009] However, the recombinant IBVs published by Zhou et al. 2016 and Hodgson et al. 2004 cannot be considered as IBVs with heterologous spike proteins, because the IBV and the inserted spike protein are from the same genotype / serotype (Massachusetts). Furthermore, all the vaccines mentioned are based on the Beaudette backbone or have a spike protein from Beaudette.
[0010] Furthermore, despite the fact that Beaudette was described decades ago and recombinant methods using Beaudette have been known for over a decade, no Beaudette-based vaccine or such recombinant vaccine (with a heterologous spike protein) is commercially available. Recombinant IBV based on Beaudette is not suitable as a vaccine. Wei et al 2014 (Apl Microbiol Biotechnol 98) disclosed a Beaudette IBV with the S1 subunit of H120.
[0011] Ellis et al 2018 (J. Virol. 92(23)), Hodgson et al (J. Virol. 78(24)), and Armesto et al 2011 (PLoS One: 6(8): e24352) all disclosed Beaudette IBV with either M41 or 4 / 91 spike proteins. However, Ellis et al 2018 (J. Virol. 92(23)) described recombinant Beaudette with a chimeric spike protein containing heterologous S1 subunits from M41 or QX combined with the S2 subunit of the Beaudette spike protein, which failed to provide adequate protection against homologous challenge with S1 (“Single vaccination of specific pathogen-free chickens with rIBV expressing S1 from virulent strains M41 or QX, i.e., BeauR-M41(S1) and BeauR-QX(S1), provided incomplete protection against homologous challenge based on ciliary motility and clinical signs”; abstract). Furthermore, Ellis et al 2018 (J. Virol. 92 (23)) described that the full-length S gene (S1 and S2 from M41) only provided partial protection against challenge with the homologous serotype IBV (page 12), suggesting that the IBV Beaudette strain is not suitable as a backbone for a recombinant IBV vaccine. Hodgson et al (J. Virol. 78 (24)) further disclosed that the Baudette strain "is also considered to be poorly immunogenic," and therefore, "has never been used as a vaccine strain" (page 13802, left column, second paragraph). Therefore, there is a need to produce new, highly effective IBV vaccines and recombinant IBV vaccines, respectively. In addition, there is a need for highly effective IBV vaccine vectors. Detailed Description of the Invention
[0013] Before describing various aspects of the present invention, it must be noted that, as used herein and in the appended claims, the singular forms "a," "an," and "the" include plural meanings unless the context clearly indicates otherwise. Thus, for example, reference to "an antigen" includes a plurality of antigens, reference to "virus" refers to one or more viruses and their equivalents known to those skilled in the art, and so on. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the art to which the invention pertains. Although any methods and materials similar or equivalent to those described herein can be used in the practice or testing of the present invention, preferred methods, devices, and materials are now described. For the purpose of describing and disclosing cell lines, vectors, and methodologies reported in publications that can be used with the present invention, all publications mentioned herein are incorporated herein by reference in their entirety. Nothing herein should be construed as an admission that the present invention is not entitled to antedate these disclosures by virtue of prior invention.
[0014] Composition of matter
[0015] The present invention solves the problems inherent in the prior art and provides a significant advancement in the art.
[0016] Generally, the present invention provides an H52 IBV (Infectious Bronchitis Virus) encoding a heterologous IBV S (Spike) protein or a fragment thereof.
[0017] The term "H52 IBV" is well known to those skilled in the art. The term "IBV" refers to infectious bronchitis virus. The term "H52" defines a specific strain of IBV. The H52 strain is well known to those skilled in the art and belongs to the Massachusetts genotype. IBV strains are typically distinguished by the coding sequence of the spike protein S1 subunit (Valastro et al. 2016. Infect Genet Evol. 39:349-364), but can also be distinguished by their complete nucleotide sequence or the sequence of specific proteins such as the spike protein, nucleocapsid protein, envelope (E) protein, or membrane (M) glycoprotein. Because the spike protein determines the host tropism and antigenicity of IBV, IBV genotypes are classified by the coding sequence of the spike protein subunit 1. Alternatively, IBV strains can be distinguished by their serotype. Serotyping involves treating the virus with neutralizing antibodies.
[0018] Furthermore, H52 and H120 could be distinguished by their higher pathogenicity after administration to young chickens.
[0019] How to obtain H52 IBV is common knowledge among those skilled in the art. H52 IBV strains are commercially available, for example, Nobilis IB H52 (MSD Animal Health), AviPro IB H52 (Lohmann Animal Health GmbH & Co. KG), Bronchovac (Ceva), etc. In addition, McDonald et al. 1980 (Avain Pathology 9:245-259) disclosed that H52 IBV can be obtained through the Central Veterinary Laboratory Rotterdam, Kusters (J. gen Virol 68:343-352) disclosed that H52 IBV can be obtained through the Poultry Health Institute Dorn (now GD Animal Health) in the Netherlands, and Chen et al. 2007 (Avian Pathology 36 (4):269-274) disclosed that H52 IBV can be obtained through the China Institute of Veterinary Drug Control. Furthermore, H52 IBV has been used as a vaccine strain for decades (Bijlenga et al. 2004, Avian Pathology 33(6):550-557) and can therefore be isolated in the field. Methods for isolating and identifying H52 IBV strains are well known to those skilled in the art. For example, H52 IBV strains can be identified as described in Zwaagstra et al. 1992 (J. Clin. Microbiol. 30(1):79-84), Handberg et al. 1999 (Avian Pathology 28:327-335), or Callison et al. 2006 (Journal of Virological Methods 138:60-65). Zwaagstra et al. 1992 and Handberg et al. 1999, for example, disclose Massachusetts-specific primers (for the S and N proteins, respectively) for RT-PCR and sequencing, as well as reference sequences for comparison. In addition, H52 IBV has been sequenced and the genome sequence is available, for example EU 817497. Therefore, the viral genome can be generated by synthesizing its sequence and by applying a reverse genetics system.
[0020] The term "spike protein" refers to a specific protein of IBV that is well known to those skilled in the art. The spike protein is the primary inducer of antibodies and protective immune responses. Furthermore, the spike (S) protein facilitates IBV entry into cells by binding to host cell receptors and mediating viral-cell membrane fusion with the host cell. Furthermore, it determines the tissue and cell tropism of the viral strain.
[0021] The term "heterologous S (spike protein)" means that the spike protein or fragment thereof introduced into H52 IBV is from a different genotype or serotype than H52 IBV. Because H52 is a Massachusetts genotype and serotype, the heterologous spike protein is a non-Massachusetts genotype or serotype.
[0022] The terms "protein," "amino acid," and "polypeptide" are used interchangeably. The term "protein" refers to an amino acid sequence composed of naturally occurring amino acids and their derivatives. Naturally occurring amino acids are well known in the art and are described in standard textbooks of biochemistry. Within an amino acid sequence, the amino acids are linked by peptide bonds. Additionally, the two ends of an amino acid sequence are referred to as the carboxyl terminus (C-terminus) and the amino terminus (N-terminus). The term "protein" includes substantially purified proteins or protein preparations that additionally contain other proteins. Furthermore, the term also refers to protein fragments. Furthermore, it includes chemically modified proteins. Such modifications can be artificial or naturally occurring modifications, such as phosphorylation, glycosylation, myristylation, and the like.
[0023] Furthermore, the present invention also provides an immunogenic composition comprising H52 IBV (infectious bronchitis virus) encoding a heterologous S (spike) protein or a fragment thereof.
[0024] In addition, the present invention also provides an immunogenic composition comprising the IBV (Infectious Bronchitis Virus) described herein. Further, the present invention also provides an immunogenic composition comprising H52 IBV (Infectious Bronchitis Virus) encoding a heterologous S (Spike) protein or a fragment thereof.
[0025] The term "immunogenic composition" refers to a composition comprising at least one antigen that elicits an immune response in a host to which the immunogenic composition is administered. This immune response can be a cellular and / or antibody-mediated immune response to the immunogenic composition of the present invention. Preferably, the immunogenic composition induces an immune response, more preferably conferring protective immunity against one or more clinical signs of IBV infection. A host is also referred to as a "subject." Preferably, any host or subject described or referred to herein is an avian or poultry species.
[0026] Typically, an "immune response" includes, but is not limited to, the production or activation of one or more of the following: antibodies, B cells, helper T cells, suppressor T cells, and / or cytotoxic T cells and / or gamma-delta T cells specific for one or more antigens contained in the immunogenic compositions of the invention. Preferably, the host will exhibit a protective immune response or a therapeutic response.
[0027] A "protective immune response" or "protective immunity" is evidenced by a reduction or absence of clinical signs normally exhibited by an infected host, a faster recovery time and / or a shortened duration of infection in an infected host, or a reduction in pathogen titers in tissues, body fluids, or excretions.
[0028] An immunogenic composition is described as a "vaccine" if it elicits a protective immune response in the host, whereby resistance to new infection is enhanced and / or the clinical severity of disease is reduced.
[0029] H52-IBV - defined by protein coding sequence
[0030] In another specific aspect of the IBV or immunogenic composition of the invention, the H52 IBV has the nucleotide sequence as shown in EU817497 (SEQ ID NO: 78) or a sequence having at least 95%, 96%, 97%, 98%, 99%, 99.2%, 99.5%, 99.6%, 99.7%, 99.8%, 99.9%, 99.95%, 99.98% or 99.99% sequence identity thereto.
[0031] The term "nucleic acid" or "nucleic acid sequence" or "nucleotide sequence" refers to a polynucleotide including a DNA molecule, an RNA molecule, a cDNA molecule or a derivative thereof. The term encompasses single-stranded and double-stranded polynucleotides. The nucleic acids of the present invention include isolated polynucleotides (i.e., isolated from their natural environment) and genetically modified forms. In addition, chemically modified polynucleotides are also included, including naturally occurring modified polynucleotides, such as glycosylated or methylated polynucleotides, or artificially modified polynucleotides, such as biotinylated polynucleotides. In addition, the terms "nucleic acid" and "polynucleotide" are used interchangeably to refer to any nucleic acid. The terms "nucleic acid" and "polynucleotide" also specifically include nucleic acids composed of bases other than the five biologically occurring bases (adenine, guanine, thymine, cytosine and uracil).
[0032] The term "RNA" refers to any ribonucleic acid. The term encompasses single-stranded and double-stranded RNA. The RNA of the present invention includes isolated RNA (i.e., isolated from its natural environment) and genetically modified forms. In addition, chemically modified RNA is also included, including naturally occurring modified RNA, such as methylated RNA, or artificially modified RNA, such as biotinylated RNA. The term "RNA" also specifically includes RNA composed of bases other than the four biologically occurring nucleotides / bases (adenine, guanine, cytosine and uracil).
[0033] In another specific aspect of the IBV or immunogenic composition of the invention, the H52 IBV strain has a spike (S) protein having the amino acid sequence shown in AF352315 (SEQ ID NO: 79) or a sequence having at least 95%, 96%, 97%, 98%, 99%, 99.2%, 99.5%, 99.6%, 99.7%, 99.8%, 99.9%, 99.95%, 99.98% or 99.99% sequence identity thereto.
[0034] It must be understood that the spike protein or nucleic acid sequence can be used to determine whether any IBV strain is derived from H52. However, since the H52 IBV is used as a backbone and the H52 spike protein or nucleic acid sequence is replaced by a heterologous spike protein or fragment thereof, the final IBV with a heterologous spike protein does not contain any H52 spike protein or only a portion of the H52 spike protein remains.
[0035] In another specific aspect of the IBV or immunogenic composition of the present invention, the H52 IBV strain has a spike (S) protein having the amino acid sequence shown in SEQ ID NO: 1 or a sequence having at least 95%, 96%, 97%, 98%, 99%, 99.2%, 99.5%, 99.6%, 99.7%, 99.8%, 99.9%, 99.95%, 99.98% or 99.99% sequence identity thereto.
[0036] In another specific aspect of the IBV or immunogenic composition of the present invention, the H52 IBV strain has a nucleocapsid (N) protein having an amino acid sequence as shown in AY044185 (SEQ ID NO: 80) or a sequence having at least 95%, 96%, 97%, 98%, 99%, 99.2%, 99.5%, 99.6%, 99.7%, 99.8%, 99.9%, 99.95%, 99.98% or 99.99% sequence identity to at least one of the above sequences.
[0037] In another specific aspect of the IBV or immunogenic composition of the invention, the H52 IBV strain has a nucleocapsid (N) protein having an amino acid sequence as shown in AF352310 (SEQ ID NO: 81) or a sequence having at least 95%, 96%, 97%, 98%, 99%, 99.2%, 99.5%, 99.6%, 99.7%, 99.8%, 99.9%, 99.95%, 99.98% or 99.99% sequence identity thereto.
[0038] In another specific aspect of the IBV or immunogenic composition of the present invention, the H52 IBV strain has a nucleocapsid (N) protein having an amino acid sequence as shown in SEQ ID NO: 2 or a sequence having at least 95%, 96%, 97%, 98%, 99%, 99.2%, 99.5%, 99.6%, 99.7%, 99.8%, 99.9%, 99.95%, 99.98% or 99.99% sequence identity thereto.
[0039] In another specific aspect of the IBV or immunogenic composition of the invention, the H52 IBV strain has an envelope (E) protein having the amino acid sequence shown in AF317210 (SEQ ID NO: 82) or a sequence having at least 95%, 96%, 97%, 98%, 99%, 99.2%, 99.5%, 99.6%, 99.7%, 99.8%, 99.9%, 99.95%, 99.98% or 99.99% sequence identity thereto.
[0040] In another specific aspect of the IBV or immunogenic composition of the present invention, the H52 IBV strain has an envelope (E) protein having the amino acid sequence shown in SEQ ID NO: 3 or a sequence having at least 95%, 96%, 97%, 98%, 99%, 99.2%, 99.5%, 99.6%, 99.7%, 99.8%, 99.9%, 99.95%, 99.98% or 99.99% sequence identity thereto.
[0041] In another specific aspect of the IBV or immunogenic composition of the present invention, the H52 IBV strain has a membrane glycoprotein (M) having the amino acid sequence shown in AF286185 (SEQ ID NO: 83) or a sequence having at least 95%, 96%, 97%, 98%, 99%, 99.2%, 99.5%, 99.6%, 99.7%, 99.8%, 99.9%, 99.95%, 99.98% or 99.99% sequence identity thereto.
[0042] In another specific aspect of the IBV or immunogenic composition of the present invention, the H52 IBV strain has a membrane glycoprotein (M) having an amino acid sequence as shown in SEQ ID NO: 4 or a sequence having at least 95%, 96%, 97%, 98%, 99%, 99.2%, 99.5%, 99.6%, 99.7%, 99.8%, 99.9%, 99.95%, 99.98% or 99.99% sequence identity thereto.
[0043] The terms "identity" or "sequence identity" are known in the art and refer to the relationship between two or more polypeptide sequences or two or more polynucleotide sequences, i.e., the relationship between a reference sequence and a designated sequence to be compared to the reference sequence. Sequence identity is determined by sequence comparison after the designated sequence and the reference sequence have been optimally aligned to produce the highest degree of sequence similarity, and is determined by a match between the sequence strings. Based on this alignment, sequence identity can be determined on a position-by-position basis; for example, if the nucleotide or amino acid residue at a particular position is the same, then the sequences are "identical" at that particular position. The total number of such positional identities is divided by the total number of nucleotides or residues in the reference sequence to provide the percentage of sequence identity. Sequence identity can be readily calculated by known methods, including but not limited to those described in Computational Molecular Biology, Lesk, AN, ed., Oxford University Press, New York (1988), Biocomputing: Informatics and Genome Projects, Smith, DW, ed., Academic Press, New York (1993); Computer Analysis of Sequence Data, Part I, Griffin, AM, and Griffin, HG, eds., Humana Press, New Jersey (1994); Sequence Analysis in Molecular Biology, von Heinge, G., Academic Press (1987); Sequence Analysis Primer, Gribskov, M. and Devereux, J., eds., M. Stockton Press, New York (1991); and Carillo, H., and Lipman, D., SIAM J. Applied Molecular Biology. Math., 48:1073 (1988), which teachings are incorporated herein by reference. Preferred methods for determining sequence identity are designed to give maximum matching between the sequences tested. Methods for determining sequence identity are codified in publicly available computer programs that determine sequence identity between specified sequences.Examples of such programs include, but are not limited to, the GCG program package (Devereux, J., et al., Nucleic Acids Research, 12(1):387 (1984)), BLASTP, BLASTN, and FASTA (Altschul, S. F. et al., J. Molec. Biol., 215:403-410 (1990)). The BLASTX program is publicly available from NCBI and other sources (BLAST Manual, Altschul, S. F. et al., NCVI NLM NIH Bethesda, MD 20894, Altschul, S. F. et al., J. Molec. Biol., 215:403-410 (1990), the teachings of which are incorporated herein by reference). These programs use default gap weights to optimally align sequences to produce the highest level of sequence identity between a specified sequence and a reference sequence. For example, a polynucleotide having a nucleotide sequence that has at least, for example, 85%, preferably 90%, or even more preferably 95% "sequence identity" to a reference nucleotide sequence means that the nucleotide sequence of the specified polynucleotide is identical to the reference sequence, except that the specified polynucleotide sequence may include up to 15, preferably up to 10, or even more preferably up to 5 point mutations per every 100 nucleotides of the reference nucleotide sequence. In other words, in a polynucleotide having a nucleotide sequence that is at least 85%, preferably 90%, or even more preferably 95% identical to a reference nucleotide sequence, up to 15%, preferably 10%, or even more preferably 5% of the nucleotides in the reference nucleotide sequence may be deleted or substituted with another nucleotide, or up to 15%, preferably 10%, or even more preferably 5% of the total nucleotides in the reference sequence may be inserted into the reference sequence. These mutations in the reference sequence may occur at the 5' or 3' terminal positions of the reference nucleotide sequence or anywhere between those terminal positions, interspersed between individual nucleotides in the reference sequence, or in one or more contiguous groups within the reference sequence. Similarly, a polypeptide having an amino acid sequence that has at least, for example, 85%, preferably 90%, even more preferably 95% sequence identity to a reference amino acid sequence means that the amino acid sequence of the specified polypeptide is identical to the reference sequence, except that the specified polypeptide sequence may include up to 15, preferably up to 10, even more preferably up to 5 amino acid alterations for every 100 amino acids of the reference amino acid sequence.In other words, to obtain a specified polypeptide sequence having at least 85%, preferably 90%, and even more preferably 95% sequence identity to a reference amino acid sequence, up to 15%, preferably up to 10%, and even more preferably up to 5% of the amino acid residues in the reference sequence can be deleted or substituted with another amino acid, or up to 15%, preferably up to 10%, and even more preferably up to 5% of the total number of amino acids in the reference sequence can be inserted into the reference sequence. These changes in the reference sequence can occur at the amino or carboxyl terminal positions of the reference amino acid sequence or anywhere between those terminal positions, interspersed between individual residues in the reference sequence, or in one or more consecutive groups within the reference sequence. Preferably, conservative amino acid substitutions differ at residue positions that are not identical. However, conservative substitutions are not included as matches when determining sequence identity.
[0044] The terms "identity", "sequence identity" and "percent identity" are used interchangeably herein. For the purposes of the present invention, it is defined herein that in order to determine the percent identity of two amino acid sequences or two nucleic acid sequences, the sequences are aligned for optimal comparison purposes (for example, a gap can be introduced in the first amino acid sequence or nucleic acid for optimal alignment with the second amino acid or nucleic acid sequence). The amino acid or nucleotide residues at corresponding amino acid or nucleotide positions are then compared. When a position in the first sequence is occupied by the same amino acid or nucleotide residue as the corresponding position in the second sequence, the molecules are identical at that position. The percent identity between the two sequences is a function of the number of identical positions shared by the sequences (i.e., % identity = number of identical positions / total number of positions (i.e., overlapping positions) × 100). Preferably, the two sequences have the same length.
[0045] Sequence comparison can be carried out on the full length of the two sequences compared or on the fragment of the two sequences. Usually, the comparison is carried out on the full length of the two sequences compared. However, sequence identity can be compared in the region of, for example, 20, 50, 100 or more continuous amino acid residues.
[0046] The skilled artisan will appreciate that different computer programs can be used to determine the homology between two sequences. For example, a mathematical algorithm can be used to compare sequences and determine the percent identity between two sequences. In a preferred embodiment, the percent identity between two amino acid or nucleic acid sequences is determined using the Needleman and Wunsch (J. Mol. Biol. (48): 444-453 (1970)) algorithm, which has been incorporated into the GAP program in the Accelrys GCG software package (available from http: / / www.accelrys.com / products / gcg / ), using a Blosum 62 matrix or a PAM250 matrix, a gap weight of 16, 14, 12, 10, 8, 6, or 4, and a length weight of 1, 2, 3, 4, 5, or 6. The skilled artisan will appreciate that all of these different parameters will produce slightly different results when different algorithms are used, but the overall percent identity between the two sequences will not change significantly.
[0047] The protein or nucleic acid sequences of the present invention can further be used as a "query sequence" to search public databases, for example, to identify other family members or related sequences. Such searches can be performed using the BLASTN and BLASTP programs (version 2.0), as described in Altschul, et al. (1990) J. Mol. Biol. 215:403-10. BLAST protein searches can be performed using the BLASTP program with a score of 50 and a word length of 3 to obtain amino acid sequences homologous to the protein molecules of the present invention. To obtain gapped alignments for comparison purposes, the Gapped BLAST program can be used, as described in Altschul et al. (1997) Nucleic Acids Res. 25(17):3389-3402. When using BLAST and Gapped BLAST programs, the default parameters of the respective programs (e.g., BLASTP and BLASTN) can be used. See the National Center for Biotechnology Information homepage at http: / / www.ncbi.nlm.nih.gov / .
[0048] As used herein, the term "identical to the sequence of SEQ ID NO: X" is specifically understood to be equivalent to the term "identical to the sequence of SEQ ID NO: X over the length of SEQ ID NO: X" or to the term "identical to the sequence of SEQ ID NO: X over the entire length of SEQ ID NO: X". In this context, "X" is any integer selected from 1-85, and thus "SEQ ID NO: X" represents any SEQ ID NO mentioned herein.
[0049] Heterologous S protein
[0050] IBV strains
[0051] IBV strains can be classified by serotype and genotype. Serotype classification involves treating the virus with neutralizing antibodies, while genotype classification generally involves examining the sequence of the S1 (spike) protein. However, different IBV strains are well known to those skilled in the art. Infectious bronchitis virus was first discovered in the United States in the 1930s. The first IBV serotype identified was the Massachusetts type, but in addition to the initially identified Massachusetts type, several other serotypes have been identified in the United States, including Arkansas and Delaware.
[0052] The IBV strain Beaudette is a Massachusetts-type strain, generated by passage in chicken embryos for at least 150 generations. The IBV strain Beaudette was originally isolated by Beaudette and Hudson (J. Am. Vet. Med. A. 90, 51-60, 1937) and passaged in chicken embryos. Other Massachusetts-type IBV strains besides Beaudette are H120, H52, and M41. The H120 strain has been passaged for 120 generations.
[0053] IBV QX is described as a virulent local isolate of IBV that was originally isolated in China. However, the virus has spread to Europe and has been found in parts of Western Europe, primarily in the Netherlands, but also in Germany, France, Belgium, Denmark, and the United Kingdom. In addition, the QX genotype or serotype has been described in several countries in Asia and Africa.
[0054] IBV 4 / 91, commonly known as 793B, was first reported in the UK in the early 1990s and has now spread to many parts of the world. CR88 is an attenuated strain belonging to this serotype and is commercially available as a vaccine.
[0055] In the late 1990s, strains designated "Italien-02" or "Italy-02" were isolated in Italy. Sequence analysis of one of these isolates was published in 2002 (NCBI-BLAST, accession number AJ457137). However, studies have shown that this Italian-02 strain is widespread in Europe and has become one of the most predominant genotypes in the United Kingdom, Spain, France, and the Netherlands, in addition to IBV variant 4 / 91.
[0056] A new infectious bronchitis virus (IBV) genotype, designated Q1, has been circulating in China since 1996 and was first reported in Italy in 2011. Q1 is associated with increased mortality, renal lesions, and proventriculitis.
[0057] In addition, strains D274, B1648 / D8880, D1466, V1397 and Arkansas have also been identified in Europe.
[0058] How to obtain any IBV strain is common knowledge among those skilled in the art. IBV strains can be purchased commercially, obtained from research institutions, or assembled into complementary DNA, as IBV strains have been sequenced and their sequences published and can therefore be used. In addition, IBV strains can be isolated from the wild. Methods for isolating and identifying IBV strains are well known to those skilled in the art. Valter Leonardo de Quadros 2011 (Dissertation, Das Bronchitis Virus(IBV):Molekularbiologische Untersuchungen zur Diagnostik undzum Vorkommen sowie zur des Genotyps IBV QX in spezifischpathogenfreien(SPF)Broilern,Freie Berlin), Worthington et al. 2009 (Avian Pathology 37(3), 247-257), Liu et al. 2009 (Virus Genes 38: 56-65), Dolz et al. 2006 (Avian Pathology 35(2): 77-85), Farsang et al. 2002 (Avian Pathology 31: 229-236) and Feng et al. 2014 (Virus Genes 49: 292-303) describe how to isolate and differentiate different IBV strains.

[0074] In another specific aspect of the IBV or immunogenic composition of the invention, the heterologous S protein or fragment thereof is from a variant 2 genotype or serotype having at least 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, 99.2%, 99.5%, 99.6%, 99.7%, 99.8%, 99.9%, 99.95%, 99.98% or 99.99% sequence identity to SEQ ID NO: 13 or 14.
[0075] In another specific aspect of the IBV or immunogenic composition of the invention, the heterologous S protein or fragment thereof is from the Brazil genotype or serotype, which has at least 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, 99.2%, 99.5%, 99.6%, 99.7%, 99.8%, 99.9%, 99.95%, 99.98% or 99.99% sequence identity with SEQ ID NO:15 or 16.
[0076] In another specific aspect of the IBV or immunogenic composition of the invention, the heterologous S protein or fragment thereof is selected from SEQ ID NO: 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 or 16.
[0077] In another specific aspect of the IBV or immunogenic composition of the invention, the heterologous S protein is a full-length spike protein.
[0078] The experimental data of the present invention show that fragments of the spike protein sequence, such as the extracellular domain of the spike protein, can be used. However, the full-length spike protein sequence can also be used.
[0079] In another specific aspect of the IBV or immunogenic composition of the invention, the fragment of the heterologous S (Spike) protein is at least 500, 750, 1000 or 1077 amino acids in length.
[0080] In another specific aspect of the IBV or immunogenic composition of the invention, the fragment of the heterologous S (Spike) protein is at least 500, 750, 1000 or 1077 amino acids in length from the N-terminus.
[0081] The term "N-terminus" is well known to those skilled in the art. The N-terminus is also referred to as the amino terminus, NH2-terminus, N-terminus, or amine terminus. When a protein is translated from messenger RNA, it is produced from the N-terminus to the C-terminus. Thus, the N-terminus is the starting point of the amino acid chain (protein or polypeptide) that contains the amine group (-NH2).
[0082] In another specific aspect of the IBV or immunogenic composition of the invention, the fragment of the heterologous S (Spike) protein is at least 1000 amino acids in length.
[0083] In another specific aspect of the IBV or immunogenic composition of the invention, the fragment of the heterologous S (Spike) protein is the extracellular domain of the Spike protein.
[0084] The term "ectodomain" is well known to those skilled in the art. The spike protein comprises distinct functional parts, namely, a signal sequence, an extracellular domain, a transmembrane domain, and an intracellular domain (from N-terminus to C-terminus). Thus, after cleavage of the signal sequence, the N-terminus of the spike protein begins with the extracellular domain. The length of the IBV spike protein extracellular domain is approximately 1077 amino acids, varying by a few amino acids depending on the IBV strain.
[0085] In another specific aspect of the IBV or immunogenic composition of the invention, the heterologous S (spike) protein or fragment thereof replaces the homologous S protein or fragment thereof.
[0086] In another specific aspect of the IBV or immunogenic composition of the invention, the heterologous S (spike) protein or fragment thereof replaces the naturally occurring S protein or fragment thereof.
[0087] In another specific aspect of the IBV or immunogenic composition of the present invention, the heterologous S (spike) protein or fragment thereof replaces the S protein or fragment thereof in H52 IBV.
[0088] In another specific aspect of the IBV or immunogenic composition of the invention, the IBV is attenuated.
[0089] The term "attenuated" refers to a pathogen that has reduced virulence compared to a wild-type isolate. In the present invention, an attenuated IBV is a strain in which virulence has been reduced so that it does not cause clinical signs of IBV infection but is able to induce an immune response in a target animal, but can also refer to a reduction in the occurrence or severity of clinical signs in an animal infected with attenuated IBV compared to a "control" animal that is not infected with attenuated IBV or does not receive attenuated virus. In this context, the term "reduced / reduced" refers to a reduction of at least 10%, preferably 25%, even more preferably 50%, even more preferably 60%, even more preferably 70%, even more preferably 80%, even more preferably 90%, even more preferably 95%, and most preferably 100%, compared to a control group infected with attenuated IBV as defined above. Therefore, an attenuated IBV strain is a strain suitable for incorporation into an immunogenic composition comprising a modified live IBV.
[0090] In another specific aspect of the IBV or immunogenic composition of the invention, the IBV is inactivated.
[0091] Any conventional inactivation method can be used for the purpose of the present invention. Therefore, inactivation can be carried out by chemical and / or physical treatment methods known to those skilled in the art. Preferred inactivation methods include adding cyclized binary ethyleneimine (BEI), including adding 2-bromoethyleneamine hydrobromide (BEA) solution that has been cyclized to binary ethyleneimine (BEI). Preferred other chemical inactivators include but are not limited to Triton X-100, sodium deoxycholate, hexadecyltrimethylammonium bromide, β-propiolactone, thimerosal, phenol and formaldehyde (formalin). However, inactivation can also include a neutralization step. Preferred neutralizing agents include but are not limited to sodium thiosulfate, sodium bisulfite, etc.
[0092] Preferred formalin inactivation conditions include a formalin concentration of about 0.02% (v / v) to 2.0% (v / v), more preferably about 0.1% (v / v) to 1.0% (v / v), still more preferably about 0.15% (v / v) to 0.8% (v / v), even more preferably about 0.16% (v / v) to 0.6% (v / v), and most preferably about 0.2% (v / v) to 0.4% (v / v). The incubation time depends on the resistance of the IBV. Generally, the inactivation procedure is performed until no IBV growth is detected in a suitable culture system.
[0093] Preferably, the inactivated IBV of the present invention is formalin-inactivated, preferably using the concentrations described herein above.
[0094] The inactivated IBV of the present invention can be incorporated into liposomes using known techniques, such as described in Nature 1974, 252, 252-254 or Journal of Immunology, 1978, 120, 1109-13. In another embodiment of the present invention, the inactivated IBV of the present invention can be conjugated to a suitable biological compound such as a polysaccharide, peptide, protein, or the like, or a combination thereof.
[0095] In another specific aspect of the IBV or immunogenic composition of the invention, the IBV is genetically engineered.
[0096] The term "genetically engineered" refers to an IBV that has been mutated using a "reverse genetics" approach. Preferably, the IBV of the present invention has been genetically engineered. Reverse genetics techniques involve the preparation of synthetic recombinant viral RNA. However, "reverse genetics" techniques are well known to those skilled in the art.
[0097] In another specific aspect of the IBV or immunogenic composition of the invention, the IBV is a recombinant IBV.
[0098] As used herein, the term "recombinant" refers to an RNA genome (or RNA sequence, cDNA sequence or protein) that has any modification that is not naturally present in the corresponding RNA genome (or RNA sequence, cDNA sequence or protein). For example, an RNA genome (or RNA sequence, cDNA sequence or protein) is considered to be "recombinant" if it contains insertions, deletions, inversions, relocations or point mutations that are artificially introduced, for example, by human intervention. Thus, the RNA genome sequence (or RNA sequence, cDNA sequence or protein) is not associated with all or part of the sequence (or RNA sequence, cDNA sequence or protein) that is naturally associated with it. The term "recombinant" used with respect to viruses refers to viruses produced by artificial manipulation of the viral genome. The term "recombinant virus" includes genetically modified viruses.
[0099] In another specific aspect of the IBV or immunogenic composition of the invention, the IBV is chimeric.
[0100] The term "chimeric" refers to an IBV that contains one or more nucleotide sequences from another coronavirus, preferably from another IBV strain. For example, IBV H52 encoding a heterologous S (spike) protein or a fragment thereof is a chimeric IBV.
[0101] In another specific aspect of the immunogenic composition according to the present invention, the immunogenic composition is a vaccine. The term "vaccine" has been described elsewhere herein. However, if the host exhibits a protective immune response, whereby resistance to new infection is increased and / or the clinical severity of the disease is reduced, the immunogenic composition is described as a "vaccine."
[0102] In another specific aspect of the immunogenic composition according to the present invention, the immunogenic composition comprises a pharmaceutically acceptable carrier.
[0103] The term "pharmaceutically acceptable carrier" includes any and all solvents, dispersion media, coatings, stabilizers, diluents, preservatives, antibacterial and antifungal agents, isotonicity agents, adsorption delaying agents, adjuvants, immunostimulants, and combinations thereof.
[0104] "Diluents" may include water, saline, glucose, ethanol, glycerol, etc. Isotonic agents may include sodium chloride, glucose, mannitol, sorbitol, lactose, etc. Stabilizers include albumin and alkali metal salts of ethylenediaminetetraacetic acid, etc.
[0105] In another specific aspect of the immunogenic composition of the present invention, the pharmaceutically acceptable carrier is phosphate buffered saline.
[0106] Preferably, the immunogenic composition further comprises a sucrose gelatin stabilizer.
[0107] Preferably, the pharmaceutically acceptable carrier is chitosan.
[0108] Chitosan is a natural deacetylated polysaccharide derived from chitin in crustaceans (such as shrimp and crabs), insects, and other invertebrates. Recently, Rauw et al. (2009) (Vet Immunol Immunop 134:249-258) demonstrated that chitosan enhanced the cellular immune response of a live Newcastle disease vaccine, promoting its protective effect. Furthermore, Wang et al. (2012) (Arch Virol (2012) 157:1451-1461) demonstrated the potential of chitosan as an adjuvant for attenuated live influenza vaccines.
[0109] Preferably, the immunogenic composition may further include one or more other immunomodulators, such as interleukins, interferons or other cytokines.The amounts and concentrations of adjuvants and additives useful within the scope of the present invention can be readily determined by a skilled artisan.
[0110] In certain aspects, the immunogenic compositions of the present invention contain an adjuvant. As used herein, "adjuvants" may include aluminum hydroxide and aluminum phosphate, saponins such as Quil A, QS-21 (Cambridge Biotech, Cambridge, Massachusetts), GPI-0100 (Pharmaceuticals, Inc., Birmingham, Alabama), water-in-oil emulsions, oil-in-water emulsions, and water-in-oil-in-water emulsions. The emulsions may be based, in particular, on light liquid paraffin oil (European typical); isoprenoid oils such as squalane or squalene; oils produced from oligomers of alkenes, particularly isobutylene or decene. Esters of acids or alcohols containing straight-chain alkyl groups, particularly vegetable oils, ethyl oleate, propylene glycol di(caprylate / caprate), glyceryl tri(caprylate / caprate), or propylene glycol dioleate. Esters of branched fatty acids or alcohols, particularly isostearates. The oil may be used in combination with an emulsifier to form an emulsion. Emulsifiers are preferably nonionic surfactants, in particular sorbitol, mannitol (e.g., anhydromannitol oleate), ethylene glycol, polyglycerol, propylene glycol, and esters of oleic, isostearic, ricinoleic, or hydroxystearic acids, which may be optionally ethoxylated, and polyoxypropylene-polyoxyethylene copolymer blocks, in particular Pluronic products, particularly L121. See Hunter et al., Theory and Practice of Adjuvants (Ed. Stewart-Toole, DES), John Wiley & Sons, Agricultural Industry Standard, pp. 51-94 (1995) and Todd et al., Vaccine 15: 564-570 (1997). Typical adjuvants are the SPT emulsions described in Vaccine Design, Subunits, and Adjuvant Methods, ed. M. Powell and M. Newman, Plenum Press, 1995, p. 147, and the MF59 emulsions described in the same book, p. 183.
[0111] Another example of an adjuvant is a compound selected from a polymer of acrylic acid or methacrylic acid and a copolymer of maleic anhydride and an alkenyl derivative. Advantageous adjuvant compounds are cross-linked polymers of acrylic acid or methacrylic acid, particularly polymers cross-linked with polyalkenyl ethers of sugars or polyols. These compounds are known as carbomers (Phameuropa Volume 8, Issue 2, June 1996). Those skilled in the art may also refer to U.S. Patent No. 2,909,462, which describes such acrylic acid polymers cross-linked with polyols having at least 3 hydroxyl groups, preferably no more than 8 hydroxyl groups, wherein the hydrogen atoms of at least 3 hydroxyl groups are substituted with unsaturated aliphatic groups having at least 2 carbon atoms. Preferred groups are those containing 2 to 4 carbon atoms, such as vinyl, allyl, and other vinyl unsaturated groups. The unsaturated group itself may contain other substituents, such as methyl. Products sold under the name Carbopol (BFGoodrich, Ohio, USA) are particularly suitable. They are cross-linked with allyl sucrose or allyl pentaerythritol. Among them, Carbopol 974P, 934P and 971P can be mentioned. The most commonly used is Carbopol 971P. Among the copolymers of maleic anhydride and alkenyl derivatives, there is the copolymer EMA (Monsanto Company), which is a copolymer of maleic anhydride and ethylene. These polymers are dissolved in water to produce an acidic solution, which is then neutralized, preferably to physiological pH, in order to prepare an adjuvant solution to be incorporated into an immunogenic, immunological or vaccine composition.
[0112] Further suitable adjuvants include, but are not limited to, the RIBI adjuvant system (RIBI, Inc.), Block copolymers (CytRx, Atlanta, Georgia), SAF-M (Chiron, Emeryville, California), monophosphoryl lipid A, Avridine lipid amine adjuvant, heat-labile endotoxin from Escherichia coli (recombinant or otherwise), cholera toxin, IMS1314 or murine amido dipeptide, or naturally occurring or recombinant cytokines or analogs thereof, or stimulators of endogenous cytokine release, and the like.
[0113] It is expected that the adjuvant will be added in an amount of about 100 μg to about 10 mg per dose, preferably about 100 μg to about 10 mg per dose, more preferably about 500 μg to about 5 mg per dose, even more preferably about 750 μg to about 2.5 mg per dose, and most preferably about 1 mg per dose. Furthermore, the adjuvant concentration can be about 0.01 to 50% by volume of the final product, preferably about 2% to 30%, more preferably about 5% to 25%, more preferably about 7% to 22%, and most preferably a concentration of 10% to 20%.
[0114] In another specific aspect of the immunogenic composition according to the present invention, the immunogenic composition is effective in treating and / or preventing clinical signs caused by IBV in a subject in need thereof. The terms "treating and / or preventing", "clinical symptoms" and "in need thereof" have been defined elsewhere.
[0115] In another specific aspect of the immunogenic composition according to the present invention, the immunogenic composition protects against challenge with an IBV strain having a genotype or serotype of a heterologous spike protein.
[0116] In another specific aspect of the immunogenic composition according to the present invention, the immunogenic composition protects against challenge with strains of the 4 / 91, QX, Q1, Arkansas, variant 2 or Brazil genotype.
[0117] In another specific aspect of the immunogenic composition according to the present invention, the immunogenic composition protects against challenge with a 4 / 91 genotype strain.
[0118] In another specific aspect of the immunogenic composition according to the present invention, the immunogenic composition is formulated for single-dose administration.
[0119] The volume of a single dose has been defined elsewhere herein.
[0120] Furthermore, it has been shown that one dose of the immunological composition of the present invention is effective following administration of such a single dose of the immunological composition of the present invention.
[0121] In another specific aspect of the immunogenic composition according to the invention, the immunogenic composition is administered subcutaneously, intramuscularly, orally, in ovo, by spray, by drinking water or by eye drops.
[0122] In another specific aspect of the immunogenic composition according to the present invention, the immunogenic composition comprises 1 to 10 log 10 EID 50 of the IBV.
[0123] In another specific aspect of the immunogenic composition according to the present invention, the immunogenic composition comprises 2 to 5 log 10 EID 50 of the IBV.
[0124] In another specific aspect of the immunogenic composition according to the present invention, the immunogenic composition comprises 2 to 4 log 10 EID 50 of the IBV.
[0125] Reagent test kit
[0126] If desired, the composition may be present in a package or dispensing device containing one or more unit dosage forms comprising the active ingredient. For example, the package may comprise metal or plastic foil, such as a blister pack. The package or dispenser device may be accompanied by instructions for administration, preferably for administration to a subject, particularly poultry. Associated with such containers may be a notice in the form of regulations of a governmental agency governing the manufacture, use, or sale of pharmaceuticals or biological products, which notice reflects the agency's permission for the preparation, use, or sale of the drug for human use.
[0127] Thus, the present invention provides a kit comprising an IBV or immunogenic composition as described herein.
[0128] In a specific aspect of the kit according to the present invention, the kit further comprises instructions for use in treating and / or preventing poultry diseases.
[0129] In a specific aspect of the kit according to the present invention, the kit further comprises instructions for treating and / or preventing poultry diseases.
[0130] In a particular aspect of the kit according to the present invention, the kit further comprises instructions for use in the treatment and / or prevention of IB (infectious bronchitis).
[0131] Treatment
[0132] Furthermore, the present invention provides methods for immunizing a subject comprising administering to the subject an immunogenic composition as described herein.
[0133] The term "immunization" refers to active immunization by administering an immunogenic composition to a subject to be immunized, thereby eliciting an immune response against the antigen contained in such immunogenic composition.
[0134] Preferably, immunization results in a reduced incidence of a specific IBV infection in a population or a reduced severity of clinical signs caused by or associated with a specific IBV infection.
[0135] In addition, immunization of a subject in need thereof with the immunogenic composition provided herein results in the subject being protected from infection with IBV. Even more ideally, the immunization results in an effective, long-lasting immune response to IBV infection. It will be understood that the time period will last for more than 1 month, preferably more than 2 months, preferably more than 3 months, more preferably more than 4 months, more preferably more than 5 months, and more preferably more than 6 months. It should be understood that immunization is not necessarily effective for all immunized subjects. However, the term requires that a substantial portion of the subjects in the population be effectively immunized.
[0136] Preferably, in this context, a population of subjects is considered that would normally develop clinical signs typically caused by or associated with IBV infection, i.e., unimmunized. Whether such subjects have been effectively immunized can be further determined by one skilled in the art. Preferably, immunization is effective if at least 33%, at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, more preferably at least 95%, and most preferably 100% of the subjects in a population have a reduction in the incidence or severity of clinical signs of at least 10%, more preferably at least 20%, more preferably at least 30%, even more preferably at least 40%, more preferably at least 50%, even more preferably at least 60%, more preferably at least 70%, more preferably at least 80%, more preferably at least 90%, more preferably at least 95%, and most preferably 100%, compared to unimmunized subjects or subjects immunized with a previously available immunogenic composition of the present invention who are subsequently infected with a specific IBV.
[0137] Furthermore, the present invention provides a method of treating or preventing clinical signs caused by IBV in a subject in need thereof, the method comprising administering to the subject a therapeutically effective amount of an immunogenic composition as described herein.
[0138] The term "treating or preventing" refers to reducing the incidence of a specific IBV infection in a population, or reducing the severity of clinical signs caused by or associated with a specific IBV infection. Therefore, the term "treating or preventing" also refers to reducing the number of subjects infected with a specific IBV in a population (= reducing the incidence of a specific IBV infection), or reducing the severity of clinical signs typically associated with or caused by an IBV infection, or reducing viral shedding following infection with a specific IBV, or preventing or reducing egg drop in laying hens following infection with a specific IBV, in comparison to a group of subjects that have not received such an immunogenic composition.
[0139] "Treatment or prevention" generally involves administering an effective amount of an immunogenic composition of the present invention to a subject or group of subjects in need of or who would benefit from such treatment / prevention. The term "treatment" refers to administering an effective amount of an immunogenic composition once a subject or at least some of the subjects in the group have been infected with such IBV and wherein such subjects have shown some clinical signs caused by or associated with such IBV infection. The term "prevention" refers to administering to a subject before the subject has been infected with IBV, or at least when no subject in the subject or group of subjects has shown any clinical signs caused by or associated with such IBV infection. The terms "prevention" and "prevent" are used interchangeably in this application.
[0140] As used herein, the term "effective amount" refers to, but is not limited to, an amount of an antigen that elicits or is capable of eliciting an immune response in a subject. Such an effective amount can reduce the incidence of a specific IBV infection in a population or reduce the severity of clinical signs of a specific IBV infection.
[0141] Preferably, the incidence or severity of clinical symptoms is reduced by at least 10%, more preferably at least 20%, more preferably at least 30%, even more preferably at least 40%, more preferably at least 50%, even more preferably at least 60%, more preferably at least 70%, more preferably at least 80%, more preferably at least 90%, more preferably at least 95%, and most preferably 100%, compared to a subject who has not received treatment or who has received the immunogenic composition available before the present invention but who subsequently becomes infected with the specific IBV.
[0142] As used herein, the term "clinical signs" refers to signs that a subject is infected with IBV. The clinical signs of infection depend on the pathogen selected. Examples of such clinical signs include, but are not limited to, respiratory distress, nephritis, salphingitis, abnormal egg production, ruffled feathers, depression, decreased growth rate, and decreased appetite. Signs of respiratory distress include respiratory signs, including wheezing, coughing, sneezing, tracheal rales, nasal and ocular discharge, tracheal lesions, and ciliostasis within the trachea. Signs of nephritis include kidney lesions and watery diarrhea. Signs of abnormal egg production include reduced egg production, smaller egg size, poorer eggshells, decreased internal egg quality, thinner egg whites, and ciliostasis within the oviducts. However, clinical signs also include, but are not limited to, clinical signs that can be observed directly in live animals. Examples of clinical signs that can be observed directly in live animals include nasal and ocular discharge, coughing, wheezing, sneezing, tracheal rales, ruffled feathers, conjunctivitis, weight loss, decreased growth rate, decreased appetite, dehydration, watery diarrhea, lameness, lethargy, emaciation, and inactivity.
[0143] Preferably, the reduction in the incidence or severity of clinical symptoms in a treated subject refers to a reduction in ciliary arrest, a reduction in rales, a reduction in egg dropping, a reduction in renal lesions, a reduction in watery diarrhea, a reduction in weight loss, a reduction in viral load, a reduction in viral shedding, or a combination thereof, compared to a subject who has not received treatment or who has received a previously available immunogenic composition of the present invention but who is subsequently infected with a particular IBV.
[0144] As used herein, the term "need" or "in need thereof" means that the administration / treatment is associated with enhancing or improving health or clinical signs or having any other positive medical effect on the health of the subject receiving the immunogenic composition of the present invention.
[0145] The terms "reduce" or "reduction" or "alleviate" or "lower" are used interchangeably herein. The term "reduce" refers to a reduction in clinical signs of at least 10%, more preferably at least 20%, more preferably at least 30%, even more preferably at least 40%, more preferably at least 50%, even more preferably at least 60%, more preferably at least 70%, more preferably at least 80%, more preferably at least 90%, more preferably at least 95%, and most preferably 100%, compared to a subject who has not received treatment (not immunized) but is subsequently infected with a particular IBV.
[0146] Additionally, the present invention provides methods of reducing ciliary arrest in a subject in need thereof, compared to a non-immunized control group of subjects of the same species, comprising administering to the subject a therapeutically effective amount of an immunogenic composition as described herein.
[0147] As shown in the Examples, the immunogenic compositions provided herein have been demonstrated to be effective in reducing ciliary arrest.
[0148] The term "ciliostasis" refers to a decrease in the movement of cilia in the trachea. Therefore, ciliary arrest can be determined by examining the lining of the tracheal rings to determine the movement of cilia. How to determine the movement of cilia in the trachea is within the general knowledge of those skilled in the art.
[0149] Preferably, ciliary motility is not reduced starting from day 10 after challenge or infection, more preferably starting from day 5 after challenge or infection, more preferably starting from day 4 after challenge or infection, more preferably starting from day 3 after challenge or infection, and most preferably starting from day 1 or day 2 after challenge or infection with IBV, compared to subjects in a non-immune control group of the same species.
[0150] The term "reduction of ciliary arrest" refers to a reduction of ciliary arrest by at least 10%, preferably at least 20%, more preferably at least 30%, even more preferably at least 40%, even more preferably at least 50%, even more preferably at least 60%, even more preferably at least 70%, even more preferably at least 80%, even more preferably at least 90%, even more preferably at least 95%, and most preferably 100%, compared to a non-immunized control group of the same species. How to measure a reduction in ciliary arrest is within the general knowledge of those skilled in the art.

[0164] In one aspect of the invention, the immunogenic composition is administered in two or more doses.
[0165] However, the immunogenic composition may be administered in two or more doses, with a first dose being administered before a second dose (boost dose).
[0166] In preferred aspects of the two-dose regimen, the first and second doses of the immunogenic composition are administered in the same amount. Preferably, each dose is the preferred amount specified above. In addition to the first and second dose regimens, alternative embodiments also include other subsequent doses. For example, a third, fourth, or fifth dose may be administered in these aspects. Preferably, the subsequent third, fourth, and fifth dose regimens are administered in the same amount as the first dose, and the time frame between each dose is consistent with the time frame between the first and second doses described above.
[0167] Preferably, the first administration of the vaccine is carried out within three weeks of age, more preferably within one week of age, and most preferably by the following method at one day of age. The second administration can be carried out within 20 weeks of age, preferably within 16-18 weeks of age, more preferably within 6-12 weeks of age. Exemplarily, an initial (first) vaccination is carried out at 1-10 days of age, and a second vaccination (enhancement) is carried out using a live vaccine or an inactivated vaccine at 6-12 or 16-18 weeks of age. More preferably, an initial (first) vaccination is carried out at one day of age, and a second vaccination (enhancement) is carried out using a live vaccine or an inactivated vaccine at 6-12 or 16-18 weeks of age.
[0168] Where an in ovo vaccine is used, the first administration is preferably given when the embryo is between 15 and 19 days old, preferably on day 17, 18 or 19, and most preferably on day 18. The second administration may be given within the first three weeks of life, and preferably within the first 10 days of life.
[0169] In one aspect of the invention, the immunogenic composition is administered subcutaneously, intramuscularly, orally, in ovo, via spray, via drinking water or via eye drops.
[0170] The immunogenic composition is preferably administered topically or systemically. Suitable routes of administration for conventional use are oral or parenteral administration, such as intranasal, intravenous, intradermal, transdermal, intramuscular, intraperitoneal, subcutaneous, and inhalation, in ovo, by spraying, by drinking water, or by eye drops. However, depending on the properties and mode of action of the compound, the immunogenic composition may also be administered by other routes. For example, such other routes include transdermal, intravenous, intravascular, intraarterial, intranasal, intrathoracic, intratracheal, intracardiac, intraperitoneal, intraperitoneal, intramedullary, extraperitoneal, intrarectal, and intravaginal. However, most preferably, the immunogenic composition is administered subcutaneously, intramuscularly, orally, in ovo, by spraying, by drinking water, or by eye drops.
[0171] The live IBV vaccine is preferably administered alone via eye drops, intranasally, intramuscularly or subcutaneously.
[0172] More preferably, a number of administration methods are used, including drinking water and aerosol vaccination.Also preferred is the use of the vaccine as an embryonic vaccine (so called in ovo vaccine), as further described below.
[0173] For example, broilers can be vaccinated at one day old or 1-3 weeks of age, especially for broilers with high MDA levels. Layers or breeders can initially be vaccinated at 1-10 days of age and boosted with the vaccine at 7-12 or 16-18 weeks of age.
[0174] In ovo administration
[0175] As described above, the present invention also provides an IBV vaccine that can be safely administered via the intra-ovo route while simultaneously inducing a protective immune response. In-ovo administration is well known to those skilled in the art, and those skilled in the art can perform intra-ovo administration without much effort. In-ovo administration of the vaccine involves administering the vaccine to an avian embryo contained in an egg (for a review of intra-ovo vaccination, see: Ricks et al., Veterinary Advances. 495-515, 1999). The vaccine can be injected into any suitable compartment of the egg (such as the allantoic fluid, yolk sac, amniotic membrane, air cell, or into the embryo), as described in the art (Sharma; Am. J. Vet. Res. 45 1619-1623, 1984). Preferably, the vaccine is administered below the shell (air cell) membrane and the chorioallantoic membrane.
[0176] Preferably, the vaccine is injected into embryonic eggs at a later stage of embryonic development, typically in the last quarter of the incubation period, preferably 3-4 days before hatching. This is preferably done when the embryos are 15 to 19 days old, preferably on days 17, 18, or 19, and ideally on day 18. The vaccinated embryonic eggs are then transferred to an incubator for incubation. The in ovo administration process can be automated using robotic injection techniques described in the prior art.
[0177] Conventional vaccines typically used for post-hatch vaccination of poultry cannot be used for in ovo vaccination because late embryos are highly sensitive to most vaccine viruses examined. However, International Patent Application WO 01 / 64244 discloses that IBV vaccines can be administered in ovo, but only at very low doses. Furthermore, Wakenell et al., 1986 (Am. J. Vet. Res., 47933-938) disclose that passage of IB vaccine viruses in tissue culture renders them nonpathogenic to embryos.
[0178] In one aspect of the invention, the immunogenic composition is administered by eye drops.
[0179] Typically, live vaccines for post-hatch administration consist of attenuated IBV at a concentration of 10 1 to 10 8 EID 50 (50% egg infectious dose), preferably 10 per dose 2 to 10 5 EID 50 , more preferably 10 per dose 2 to 10 4 EID 50 , even more preferably 10 per dose 2 to 10 3 EID 50 .
[0180] Live vaccines for in ovo administration typically contain 10 2 -10 7 EID 50 / embryo, preferably 10 2 -10 3 EID 50 / embryo-attenuated IBV.
[0181] Preferably, the immunogenic compositions of the present invention include the IBV of the present invention in an amount of about 1 to about 10 log 10 EID (Egg Infectious Dose) 50 , preferably from about 2 to about 8 log per dose 10 EID 50 , preferably from about 2 to about 7 log per dose 10 EID 50 , more preferably from about 2 to about 6 log per dose 10 EID 50 Even more preferably, about 2 to about 5 log per dose 10 EID 50 Even more preferably, about 2 to about 4 log per dose 10 EID 50 The amount of , most preferably about 2 to about 3 log per dose 10 EID 50 More preferably, the immunogenic compositions of the invention include the IBV of the invention in an amount of about 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5 or log 1, 2, 3, 4, 5, 6, 7, 8 ... 10 EID 50 .
[0182] In one aspect of the invention, the immunogenic composition comprises 1 to 10 log 10 IBV of EID50.
[0183] In one aspect of the invention, the immunogenic composition comprises 2 to 5 log 10 IBV of EID50.
[0184] In one aspect of the invention, the immunogenic composition comprises 2-4 log 10 IBV of EID50.
[0185] In one aspect of the invention, the immunogenic composition is administered to a subject within one week of age, within three days of age, within two days of age, or within one day of age.
[0186] Preferably, the subject to be immunized is 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, or 21 days old. More preferably, the subject to be immunized is 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, or 14 days old. Most preferably, the subject to be immunized is 1, 2, 3, 4, 5, 6, or 7 days old.
[0187] However, it must be understood that it does take several days for the poultry's immune system to build up immunity to IBV infection after vaccination of the subject. Therefore, vaccination is best performed within the first 24 hours of the subject's life.
[0188] In one aspect of the invention, the immunogenic composition is administered to a subject within the first day of life.As shown in the Examples, the immunogenic compositions provided herein have been shown to be safe and effective when administered to one-day-old poultry.
[0189] In one aspect of the invention, the method results in an improvement in an efficacy parameter selected from the group consisting of prevention or reduction of ciliary arrest, prevention or reduction of rales, prevention or reduction of egg loss, prevention or reduction of renal lesions, prevention or reduction of watery diarrhea, reduction in weight loss, reduction in viral load, reduction in viral shedding, or a combination thereof, compared to subjects in an untreated control group of the same species.
[0190] The terms "treating and / or preventing" have been defined elsewhere, wherein the terms "preventing" and "preventing" or "avoiding" are used interchangeably in this application. In addition, the term "shedding" has also been defined elsewhere.
[0191] The terms "reduce", "lower", "alleviate" or "become lower" refer to a decrease in efficacy parameters (ciliostasis, rales, egg loss, kidney lesions, watery diarrhea, weight loss, viral load, viral shedding) by at least 10%, preferably at least 20%, more preferably at least 30%, even more preferably at least 40%, even more preferably at least 50%, even more preferably at least 60%, even more preferably at least 70%, even more preferably at least 80%, even more preferably at least 90%, even more preferably at least 95% and most preferably 100% compared to a non-immunized control group of the same species. How to measure the improvement of efficacy parameters is common knowledge to those skilled in the art.
[0192] The term "viral load" is well known to those skilled in the art. The term viral load is used interchangeably with viral titer herein. Viral load or viral titer is a measure of the severity of an active viral infection and can be determined by methods known to those skilled in the art. Determination can be based on the detection of viral proteins, such as by antibodies binding to viral proteins and further detecting them, or by detecting viral RNA by amplification methods such as RT-PCR. Monitoring viral RNA associated with the virus in plasma by nucleic acid amplification methods is a widely used parameter for assessing the status and progression of retroviral diseases and for assessing the effectiveness of preventive and therapeutic interventions. For example, viral load or viral titer can be calculated by estimating the number of viable viruses in the body fluid in question, such as the number of RNA copies per milliliter of plasma.
[0193] The term "ciliostasis" is well known to those skilled in the art. The surface of the trachea is covered with specialized epithelial cells lined with numerous, mobile, hair-like structures called cilia. The term "ciliostasis" encompasses a reduction or loss of cilia and / or a loss or partial loss of ciliary activity. Ciliosis can be determined without undue effort by those skilled in the art.
[0194] The term "rales" is well known to those skilled in the art. However, the term "rales" includes tracheal rales and refers to sounds emitted from the bronchi. Those skilled in the art can determine rales without undue effort.
[0195] The term "egg drop" is well known to those skilled in the art. The term "egg drop" includes a reduction in egg production.
[0196] In one aspect of the invention, treatment or prevention results in prevention or reduction of ciliary arrest compared to an untreated control group of subjects of the same species.
[0197] In one aspect of the invention, the treatment or prevention results in the prevention or reduction of kidney pathology compared to an untreated control group of subjects of the same species.
[0198] In one aspect of the invention, the treatment or prevention results in the prevention or reduction of egg drop compared to an untreated control group of subjects of the same species.

[0359] Example 1: Generation of recombinant IBV H52, wherein the coding sequence of the H52 spike protein or spike protein ectodomain is replaced by the coding sequence of a heterologous spike protein or spike protein ectodomain
[0360] Construction of donor plasmid
[0361] An example of replacing the H52 spike protein ectodomain with the CR88 ectodomain is described in detail: The IBV CR88 spike protein nucleic acid coding sequence (SEQ ID NO: 17) was synthesized by a commercial supplier. It was used as a template to replace the IBV H52 spike protein ectodomain nucleic acid coding sequence (SEQ ID NO: 18) in the pUC57-s IBV-5-1b-S-SIR-3T donor plasmid described by van Beurden et al. (Virol J. 2017; 14(1): 109), hereinafter referred to as the pUC57-s H52 rIBV donor plasmid (SEQ ID NO: 19). Bases 1717 to 4941 of SEQ ID NO: 19 were replaced with the corresponding IBV CR88 spike protein ectodomain nucleic acid coding sequence (SEQ ID NO: 20), which correspond to bases 55 to 3285 of SEQ ID NO 15, respectively. This generated the pUC57-s H52 rIBV CR88 S Ecto donor plasmid (SEQ ID NO: 21), in which the IBV CR88 spike protein ectodomain is encoded from bases 1717 to 4947. To this end, the pUC57-s H52 rIBV donor plasmid (SEQ ID NO: 19) was digested with unique restriction enzyme sites 5' (EcoRV) and 3' (PmlI) close to the H52 spike protein coding sequence to linearize the plasmid and remove the H52 spike protein and flanking sequences. The QIAquick gel extraction kit (Qiagen) was used to purify the band corresponding to the pUC57-sIBV H52 backbone without the H52 spike protein coding sequence. The CR88 spike protein ectodomain coding sequence and flanking 5' and 3' IBV H52 sequences were amplified in three separate PCR reactions using high-fidelity DNA polymerase (NEB; see Table 1 for primers). PCR products were purified by QIAquick gel extraction (Qiagen) and used for Gibson assembly with the HiBuild DNA Assembly Cloning Kit (NEB) according to the kit protocol to generate the pUC57-s H52 rIBV CR88S Ecto donor plasmid.

[0364] Targeted RNA recombination and rescue of recombinant IBV
[0365] For the generation of recombinant IBV, the method of targeted RNA recombination as described by van Beurden et al. (Virol J. 2017; 14(1): 109) was used. Briefly, H52 murinized (m)IBV was generated as described. To generate H52 rIBVCR88 S Ecto, LR7 cells were infected with H52 mIBV and electroporated with in vitro transcripts generated from the pUC57-s H52 rIBV CR88 S Ecto donor plasmid, which were then injected into 8-day-old embryonated SPF chicken eggs (VALOBioMedia). After incubation for 9 days at 37.5°C and 60% humidity, the cells were cloned and expressed using the QIAamp Viral RNAmini Kit (Qiagen) and a Platinum PCR kit. TM SuperScript Taq DNA polymerase (ThermoFisher) TM After RNA was isolated using the III one-step RT-PCR system, allantoic fluid from all eggs was analyzed for rescued recombinant IBV. Primers PO1323 and PO1729 (Table 2) that bind to the H52 IBV 1ab and CR88 IBV S extracellular domains were used, which are specific for recombinant IBV but not for mIBV. The allantoic fluid from the egg inoculated with the highest dilution of LR7 cells was selected for two rounds of endpoint dilution in 8-day-old SPF chicken eggs. The MagMAX™ Core Nucleic Acid Purification Kit (ThermoFisher) and the KingFisher DNA Purification Kit (KingFisher) were used. TM Nucleic acid isolation of limiting dilution samples was performed using the Duo Prime purification system (ThermoFisher), and subsequent analysis of the presence of rIBV was performed by RT-PCR as described above. After the second limiting dilution, positive allantoic fluid from eggs inoculated at the highest dilution was used to propagate in 10-day-old embryonated SPF eggs. The allantoic fluid was diluted 1:1000 in 1xPBS, and 100 μl was injected into each egg. The allantoic fluid was harvested 48 hours after inoculation, cleared of debris, and stored at -80°C. To confirm the sequence of the generated rIBV from the donor plasmid, viral nucleic acid was isolated using the QIAamp viral RNA mini kit, followed by SuperScript III one-step RT-PCR using the primers listed in Table 3. QIAquick PCR purification and subsequent Sanger sequencing using the same primers were performed by commercial suppliers.

[0370] Generation and characterization of H52 recombinant IBV in which the coding sequence of the H52 spike protein or spike protein ectodomain is replaced by the coding sequence of the spike protein or spike protein ectodomain of another IBV genotype
[0371] The same methods as those described for producing H52 rIBV CR88 S Ecto were applied to produce and characterize recombinant H52 IBV, wherein the spike protein coding sequence (bases 1663 to 5151 of SEQ ID NO: 19) or the H52 spike protein extracellular domain coding sequence (bases 1717 to 4941 of SEQ ID NO: 19) was replaced with the coding sequence of the IBV spike protein or spike protein extracellular domain of the serotype and genotype listed in Table 4.

[0375]
[0376] The primers in Tables 2 and 3 were used to identify and sequence different recombinant viruses and were modified to target the corresponding spike protein sequences when necessary.
[0377] Example 2: In ovo replication dynamics
[0378] Eight eight-day-old embryonated chicken eggs were inoculated with 10 2 EID 50of rIBV and respective controls. The eggs were incubated at 37.5°C and 60% humidity and candidized daily after 0, 8, 24, 34, 48 and 72 hours of incubation, and embryonic mortality was recorded. Five pre-selected eggs were taken for each sample and time point and transferred to 4°C for at least 2 hours. Subsequently, the allantoic fluid was collected and stored at -80°C. For analysis, the samples were thawed and diluted 1:10 in 1xPBS without Ca and Mg, nucleic acids were extracted using the QIAamp DNA Blood Mini kit (Qiagen), and carrier RNA was added using a Hamilton Starlet automatic pipette. The relative amount of IBV RNA in the extracted nucleic acids was analyzed by RT-qPCR, using the protocol of Callison et al. (J Virol Methods. 2006; 138(1-2): 60-5) with some modifications. In brief, the same primers and probes were used, and the temperature protocol was adjusted to suit the use Fast Virus 1-Step Master Mix (ThermoFisher) and ABI TM 7900HT Fast Real-Time PCR System (Thermo Fisher Scientific). All nucleic acid samples were analyzed in triplicate, using 10-fold serial dilutions of IBV H52 as a reference.
[0379] Compared to the recombinant wild-type viruses H52 and CR88, H52 rIBV CR88 S Ecto observed slightly similar replication kinetics at early time points. However, after 32 hours, all viruses reached comparable ct values. All embryos were alive 32 hours after inoculation, while all remaining embryos in all samples died at the 48-hour time point after infection. Therefore, H52 rIBV CR88 S Ecto replicates as efficiently as wild-type virus (see Figure 1 ).
[0380] Example 3: Preparation of vaccines and challenge viruses
[0381] To demonstrate the efficacy of H52 rIBV with heterologous spike protein or spike protein ectodomain in chickens, an aliquot of the virus stock was thawed, diluted 10-fold in 1x PBS, and the 50% embryo infectious dose (EID) was determined by inoculating 100 μl of each dilution into five 8-day-old embryonated chicken eggs. 50). The eggs were incubated at 37.5°C and 60% humidity until 7 days after inoculation. Eggs with dead embryos after 24 hours were excluded from the experiment. All other eggs with dead embryos 7 days after inoculation were considered positive. On the 7th day after inoculation, all eggs with live embryos were candidized from the bottom to identify the bantam chicks considered positive. The EID was calculated using the formula of Reed and Muench 50 / ml (Am J Epidemiol, 1938; 27(3): 493-497). For immunization, the virus stock solution was diluted in 1xPBS to obtain 10 4.3 EID 50 / ml titer (10 per chicken in 50 μl) 3 EID 50 ).
[0382] Challenge viruses of genotypes and serotypes 793B, QX, Q1, Ark, variant 2, and Brazil were propagated in 10-day-old embryonated SPF chicken eggs. 24 hours after inoculation, the eggs were transferred to 4°C for at least 2 hours. The allantoic fluid was collected, aliquoted, and stored at -80°C. Viral titers were determined as described above. The titer was set to 10 by diluting with 1x PBS. 4.3 to 10 5.3 EID 50 / ml (10 per chicken in 50 μl) 3 to 10 4 EID 50 ).
[0383] Example 4: Determination of vaccine efficacy
[0384] Fertilized SPF chicken eggs were incubated in an egg incubator at 99.7°F and 50% humidity for 18 days with hourly turning. On the 18th day of incubation, the eggs were candidized and the fertilized eggs were transferred to an incubator and incubated at 99°F and 70% humidity until hatched. Chickens without clinical signs or deformations were randomly assigned to treatment groups and moved to separate isolators. At least two chickens were used as a strict negative control (SNC) group, five chickens were included in the challenge control (CC) group, and at least ten chickens in each group were vaccinated with recombinant IBV with a heterologous spike protein or spike protein extracellular domain and subsequently challenged. Animals were housed under housing conditions that met local and national animal welfare recommendations. The lighting regimen was adjusted to 16 hours of light per day. Feed and water were provided ad libitum. After transfer to the isolator, chickens (1 day old) were inoculated with 10 3 EID 50 / , while the SNC and CC groups remained untreated. 21 days after vaccination, the chickens in the CC and vaccinated groups were treated with 10 3 to 10 4 EID 50 / were challenged with the respective spike protein-homologous challenge strain (793B, QX, Q1, Ark, variant 2 or Brazil). On the 7th day after the challenge, all chickens were euthanized, pharyngeal swabs were taken, kidneys were removed, and stored in RNAlater stabilization solution (ThermoFisher) at 4°C for IBV-specific RT-qPCR analysis. In addition, the trachea was removed and moved to a 50 ml test tube filled with warm cell culture medium. The trachea was then cleared from the connective tissue and rinsed with cell culture medium. The trachea was cut into tracheal rings using a McIlwain tissue chopper set to 0.6-0.8 mm slice thickness. Three rings in the upper part of each trachea, four rings in the middle part, and three rings in the lower part were analyzed by light microscopy and scored for ciliary arrest (see Table 5). If more than 50% of the internal rings showed obvious ciliary movement (score 2 and lower), it was recorded as normal. If less than 50% of the cilia were motile (scores 3 and 4), the ring was scored as positive for ciliary arrest.
[0385] For IBV-specific RT-qPCR analysis, kidney tissue sections were warmed to room temperature and then transferred to separate 2 ml Precellys tubes filled with culture medium and PBS, respectively. The kidneys were homogenized at 6800 rpm for 1 x 20 seconds using a tissue homogenizer (Bertin Instruments). Throat swabs were eluted with 2 ml of 1 x PBS. MagMAX TM Core Nucleic Acid Purification Kit (ThermoFisher) and KingFisher TM The Duo Prime purification system (ThermoFisher) was used to separate nucleic acids from 200 μl of eluate and tissue homogenate. TM RT-qPCR was performed as described above for in ovo kinetics, except that analysis was performed in duplicate using a Real-Time PCR system (ThermoFisher).

[0388] Example 5: Efficacy of recombinant IBV H52 encoding heterologous spike protein or spike protein ectodomain
[0389] The aim of this study was to demonstrate that vaccination with recombinant IBV H52 (Mass genotype) encoding a heterologous spike protein or spike protein extracellular domain confers protection against challenge with a spike protein homologous challenge strain.
[0390] The study analyzed whether recombinant IBV H52 (Mass genotype) encoding the extracellular domain of the IBV CR88 (4 / 91 genotype) spike protein could confer protection against challenge with the virulent 793B strain (4 / 91 genotype), which is considered to be a homologous challenger to the encoded IBV CR88 spike protein extracellular domain and a heterologous challenger to the IBV H52 backbone. All chickens were observed daily for clinical signs. No clinical signs were recorded after vaccination or challenge. Back titration of the inoculation with H52 rIBV CR88 S Etco at 1 day of age determined that the titers of the 793B challenge virus applied on day 21 after vaccination were 10 4.13 EID 50 / ml(target 10 4.3 EID 50 / ml), and 10 4.69 EID 50 / ml(target 10 4.3 EID 50 Ciliary motility arrest was scored as described above. Figure 2 are shown and summarized in Table 6.
[0391] Table 6: Overview of the ciliary arrest protection scores at 28 days post-vaccination and 7 days post-challenge. The average ciliary arrest score for each group was calculated by adding the total scores of each chicken in each group and then dividing the group total score by the number of animals (maximum score is 40 and minimum score is 0). If no fewer than 9 out of 10 rings showed normal ciliary activity, the animal was considered unaffected.
[0392]
[0393] All animals in the strict negative control group showed normal ciliary motility, while 80% of animals in the challenge control group were positive for ciliary arrest. In contrast, 82% of animals vaccinated with H52 rIBV CR88 S Etco were protected. In addition, viral loads in kidney and nasal swabs of animals vaccinated with H52 rIBV CR88 S Etco were reduced compared with animals in the challenge control group ( Figure 3 and Figure 4 ).
[0394] In addition, we analyzed whether recombinant IBV H52 encoding the IBV QX spike protein could confer protection against challenge with the virulent D388QX strain, as a homologous challenge agent encoding the IBV QX spike protein, and as a heterologous challenge agent to the IBV H52 backbone. All birds were observed daily for clinical signs. No clinical signs were recorded after vaccination or challenge. The titer, determined by reverse titration with CH52 rIBV QX S at 1 day of age, was 10 4 EID 50 / ml, while QX vaccination exceeds 10 5 EID 50 / ml(target 10 4.3 EID 50 / ml). The titer of the virus was 10 at 21 days after inoculation when challenged with D388 QX. 4.83 EID 50 / ml(target 10 4.3 EID 50 / ml). Ciliary arrest was scored as described above, and the results were as follows. Figure 5 are shown and summarized in Table 7.
[0395] Table 7: Overview of the ciliary arrest protection scores at 28 days post-vaccination and 7 days post-challenge. The average ciliary arrest score for each group was calculated by adding the total scores of each chicken in each group and then dividing the group total score by the number of animals (maximum score is 40 and minimum score is 0). If no less than 9 out of 10 rings showed normal ciliary activity, the animal was considered unaffected.

[0397] All animals in the strict negative control group showed normal ciliary motility, while all animals in the challenge control group tested positive for ciliary arrest. In contrast, 100% of animals vaccinated with the H52 rIBV QX S or QX vaccine were protected.
[0398] Similar results were obtained with other H52 rIBVs with heterologous spike proteins or spike protein extracellular domains.
[0399] This result highlights the suitability of IBV H52 as an efficient backbone for generating recombinant IBV with heterologous spike proteins, particularly when compared to prior art data for the IBV Beaudette backbone showing excellent results.
