Description

[0001] Sequence Listing

[0002] This application contains a Sequence Listing pursuant to 37 CFR 1.821-1.825. The Sequence Listing accompanying this application is hereby incorporated by reference in its entirety. Background Art

[0003] Avian coronavirus infectious bronchitis virus (IBV) is a prototype gamma coronavirus of the Nidovirales order, Coronaviridae family. Infectious bronchitis virus primarily infects the upper respiratory epithelium of chickens, causing respiratory disease, often complicated by secondary bacterial pathogens (Cook et al. 2012. Avian Pathol. 41: 239-250). Some IBV strains additionally affect the renal tubules, oviducts, and part of the gastrointestinal tract, leading to pathological damage and clinical symptoms in these organ systems. The virus has a worldwide presence in both commercial chickens and free-range chickens. Due to its high genomic variability, IBV is divided into a wide variety of genotypes, serotypes, and protectotypes. IBV is currently considered one of the most economically relevant viral pathogens in the poultry industry.

[0004] 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 designated as gene 1), divided into two open reading frames 1a and 1b, which encode at least 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), and 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 tropism of the host species (Kuo et al. 2000.J.Virol.74:1393-1406). It is a dimeric or trimeric transmembrane protein that is proteolytically cleaved into two subunits, S1 and S2. The glycosylated S1 domain forms the 'head' of the spike protein and contains the receptor-binding domain that interacts with 2,3-linked sialic acids on the host cell surface (Promkuntod et al. 2014. Virology. 448:26-32). The S2 domain contains the remainder of the extracellular domain (the 'stem'), the transmembrane domain, and the intracellular domain located in the cytoplasm.

[0005] The widely used live attenuated IBV vaccine strains H52 and H120 were developed in the Netherlands in the 1960s by serial passage of the Massachusetts IBV strain in embryonated chicken eggs (Bijlenga et al. 2004; Avian Pathol. 33:550-557). These vaccine strains must also be cultured in embryonated chicken eggs for production. Today, IBV vaccines (both inactivated and live) are still grown in embryonated chicken eggs, which is cumbersome and expensive.

[0006] The only cell line-adapted IBV described to date is the IBV strain Beaudette, which replicates efficiently in Vero and BHK cells. Casais et al. 2003 (J. Virol. 77; 9084-9089) generated recombinant IBV using the extracellular domain sequence of the Beaudette spike and showed that the S protein of Beaudette is the determinant of cell line tropism, which is able to transfer the extended cell line tropism to another IBV (M41). WO 2011 / 004146 discloses that the S2 subunit from Beaudette is responsible for the extended tissue tropism. Sequences within the S2 subunit, derived from the heparan sulfate binding site of Beaudette, have been identified as responsible for the extended cell line tropism. In addition, Bickerton et al. 2018 (Journal of Virology 92 (19)) disclosed an eight-amino acid Beaudette-specific motif. However, recombinant IBV with the Beaudette spike S2 ​​subunit is not suitable as a vaccine. Ellis et al. 2018 (J. Virol. 92 (23)) describe that recombinant Beaudette with a chimeric spike having a heterologous S1 subunit from M41 or QX combined with the Beaudette spike S2 ​​subunit does not confer adequate protection against S1 homologous challenge. In addition, Beaudette wild type does not provide protection against homologous challenge as other licensed vaccines belonging to the Massachusetts serotype (Hodgson et al. 2004: J Virol 78: 13804–13811 or Geilhausen et al. 1973: Archiv für die gesamte Virusforschung 40: 285-290).

[0007] Fang et al. 2005 (Biochemical and Biophysical Research Communication 336; pp. 417-423) disclose that adaptation of Beaudette for propagation in Vero cells resulted in 49 amino acid modifications, 26 of which were located within the spike protein.

[0008] In summary, providing an IBV vaccine with extended cell culture or tissue tropism by exchanging the spike protein for a heterologous Beaudette spike protein does not result in an IBV vaccine that provides sufficient efficacy, and the use of the Beaudette spike sequence will be limited to protection against challenge with a Massachusetts serotype strain and lack cross-protection against further genotypes. Furthermore, the prior art motifs or sites identified in Beaudette have not yet been transferred into IBV vaccines that show both extended cell culture or tissue tropism and protective efficacy (interference between extended tropism and vaccine efficacy has not yet been shown).

[0009] Thus, there is a need for single amino acids or short motifs that can be transferred into IBV or IBV vaccines without affecting vaccine efficacy, but rather enabling extended cell or tissue tropism. DETAILED DESCRIPTION

[0010] Before describing 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 referents unless the context clearly dictates otherwise. Thus, for example, reference to "an antigen" includes a plurality of antigens, reference to "a virus" is a reference to one or more viruses and their equivalents known to those skilled in the art, and so forth. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the invention pertains. Although preferred methods, apparatus, and materials are now described, any methods and materials similar or equivalent to those described herein may be used in the practice or testing of the present invention. All publications mentioned herein are incorporated herein by reference for the purpose of describing and disclosing cell lines, vectors, and methods as reported in the publications that may be used in conjunction with the present invention. Nothing herein should be construed as an admission that the present invention is not entitled to antedate such disclosures by virtue of prior invention.

[0011] Composition of matter

[0012] The present invention solves the problems inherent in the prior art and provides a significant advancement in the state of the art.

[0013] Generally, the present invention provides an avian coronavirus spike protein or fragment thereof, wherein at least a portion of the S1 subunit is from an avian coronavirus with limited cell tropism or tissue tropism, and wherein at amino acid position 267 is cysteine.

[0014] Furthermore, the present invention provides a recombinant avian coronavirus spike protein or a fragment thereof comprising a mutation to cysteine ​​at amino acid position 267.

[0015] Generally, the present invention also provides an IBV spike protein or a fragment thereof, wherein at least a portion of the S1 subunit is from an IBV with limited cell tropism or tissue tropism, and wherein at amino acid position 267 is cysteine.

[0016] Further, the present invention provides a recombinant IBV spike protein or a fragment thereof comprising a mutation to cysteine ​​at amino acid position 267.

[0017] Advantageously, experimental data show that coronavirus strains (such as, for example, H52, QX SP2013-01478 and CR88 IBV strains) have expanded cell or tissue tropism after modifying a single position within the spike protein, position 267, to cysteine.

[0018] The term "coronavirus" is well known to those skilled in the art. In general, coronaviruses are viruses of the subfamily Coronavirinae in the family Coronaviridae, order Nidovirales. Coronaviruses are enveloped viruses with a positive-sense single-stranded RNA genome containing a helically symmetrical nucleocapsid. The term "coronavirus" includes all strains, genotypes, protective types, and serotypes of infectious bronchitis viruses. Examples of avian coronaviruses are infectious bronchitis virus (IBV); guinea fowl coronavirus (GfCoV) and turkey coronavirus (TCoV; turkey enteritis virus and blue crown virus).

[0019] The term "IBV" refers to the infectious bronchitis virus well known to those skilled in the art. The term "IBV" includes all strains, genotypes, protective types and serotypes of infectious bronchitis virus.

[0020] The term "mutation" includes modifications in viral RNA encoded proteins that result in changes in the encoded proteins. Further, the term "mutation" includes mutations in genetically engineered proteins. The term "mutation" refers to, but is not limited to, substitutions (replacement of one or several nucleotides / base pairs), deletions (removal of one, several or all nucleotides / base pairs), and / or insertions (additions of one or several nucleotides / base pairs). As used herein, mutations may be single mutations or several mutations, and therefore, the term "one or more mutations" is often used, and relates to both single mutations and several mutations. However, the term mutation is well known to those skilled in the art, and those skilled in the art can readily generate mutations.

[0021] The term "Spike" refers to a protein specific to avian coronaviruses or IBVs, 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 cellular entry of avian coronaviruses or IBVs by binding to cellular receptors on host cells and mediating virus-cell membrane fusion with the host cell membrane. Furthermore, it determines the tissue and cell tropism of the viral strain.

[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. Furthermore, 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. In addition, it includes chemically modified proteins. Such modifications can be artificial or naturally occurring modifications, such as phosphorylation, glycosylation, myristylation, and the like.

[0023] Mutation 267

[0024] In one aspect of the avian coronavirus or IBV spike protein or fragment thereof according to the invention, the cysteine ​​at amino acid position 267 is introduced by mutation. The word "introduced" means that the mutation has been introduced by genetic engineering (artificially, e.g., by human intervention).

[0025] In another specific aspect of the avian coronavirus or IBV spike protein or fragment thereof according to the present invention, the mutation is an amino acid substitution, deletion or insertion.

[0026] In another specific aspect of the avian coronavirus or IBV spike protein or fragment thereof according to the present invention, the hydrophobic amino acid at amino acid position 267 is mutated to cysteine; or the phenylalanine or leucine at amino acid position 267 is mutated to cysteine.

[0027] Extended cell tropism or tissue tropism

[0028] In another specific aspect of the avian coronavirus or IBV spike protein or fragment thereof according to the present invention, the cysteine ​​at amino acid position 267 or the mutation to cysteine ​​at amino acid position 267 results in an extended cell tropism or tissue tropism of the avian coronavirus or IBV.

[0029] The term "cell or tissue" is known to those skilled in the art. The term cell includes cell lines, such as those listed elsewhere herein, as well as primary cells. The term tissue includes cells from tissues such as those listed elsewhere herein, illustratively such as primary chicken embryonic cells or primary chicken fibroblasts from the lung or liver. The term includes the propagation of cells or tissues (cells) in culture outside an organism. The term "culture" relates to the propagation of cells (e.g., cell line cells or primary cells or tissue cells) outside an organism under defined culture conditions known to those skilled in the art.

[0030] The term "extended tropism" means that avian coronavirus of the present invention or IBV can be bred in cells (e.g., cell lines) or tissue cells (except the primary chicken embryo cells from the kidney). In contrast, wild-type coronavirus or IBV (describing the IBV Beaudette strain adapted to cell line) of coronavirus vaccines (e.g., IBV vaccines) or non-cellular culture adaptation can only be bred in embryonated eggs or primary chicken embryo cells from the kidney (after adaptation). Accordingly, the coronavirus of the present invention (e.g., IBV) with expanded cell tropism or tissue tropism has the ability to infect and / or replicate in one or more cell lines or tissue cells except the primary chicken embryo cells from the kidney. Preferably, the coronavirus of the present invention (e.g., IBV) with expanded cell tropism or tissue tropism has the ability to infect and / or replicate in one or more cell lines as listed herein. Accordingly, for example, the coronavirus or IBV with expanded cell tropism or tissue tropism may have the ability to infect and / or replicate in PBS-12SF, EB66 or HEK 293T cells.

[0031] The term "restricted tropism" means that avian coronaviruses or IBVs can only grow on primary chicken embryo cells from kidney. Accordingly, coronaviruses or IBVs with restricted cell or tissue tropism do not have the ability to infect and / or replicate in, for example, PBS-12SF, EB66 or HEK 293T cells.

[0032] Advantageously, experimental data show that IBV strains, such as exemplified by H52 and CR88, have expanded cell or tissue tropism after modifying a single position within the spike protein, position 267, to cysteine. Further, it has been shown that modification to cysteine ​​at position 267 is genetically stable.

[0058] spike

[0059] The present invention also provides a spike protein or a fragment thereof as described above, wherein the spike protein or a fragment thereof is selected from: infectious bronchitis virus (IBV); guinea fowl coronavirus (GfCoV), turkey coronavirus (TCoV; turkey enteritis virus and blue crown virus), feline infectious peritonitis virus (FIPV), feline enteric coronavirus (FECV); transmissible gastroenteritis virus (TGEV), porcine respiratory coronavirus (PRCoV), porcine epidemic diarrhea virus (PEDV), porcine hemagglutinating encephalomyelitis virus (PHEV); severe acute respiratory syndrome coronavirus (SARS-CoV), Middle East respiratory syndrome coronavirus (MERS-CoV), human coronavirus 229E (HCoV-229E), human coronavirus NL63 (HCoV-NL63), human coronavirus HKU1 (HCoV-HKU1), human coronavirus OC43 (HCoV-OC43); canine coronavirus (CCoV), canine respiratory coronavirus (CRCoV), mouse hepatitis virus (MHV), bovine coronavirus (BCV). Thus, the present invention also provides a coronavirus spike protein or a fragment thereof, wherein at least a portion of the S1 subunit is from a coronavirus with limited cell tropism or tissue tropism, and wherein at amino acid position 267 is cysteine, and wherein the spike protein is selected from the group consisting of: infectious bronchitis virus (IBV); guinea fowl coronavirus (GfCoV), turkey coronavirus (TCoV; turkey enteritis virus and blue crown virus), feline infectious peritonitis virus (FIPV), feline enteric coronavirus (FECV); transmissible gastroenteritis virus (TGEV), porcine respiratory coronavirus (PRCoV), porcine epidemic coronavirus (PCoV), Porcine diarrhea virus (PEDV), porcine hemagglutinating encephalomyelitis virus (PHEV); severe acute respiratory syndrome coronavirus (SARS-CoV), Middle East respiratory syndrome coronavirus (MERS-CoV), human coronavirus 229E (HCoV-229E), human coronavirus NL63 (HCoV-NL63), human coronavirus HKU1 (HCoV-HKU1), human coronavirus OC43 (HCoV-OC43); canine coronavirus (CCoV), canine respiratory coronavirus (CRCoV), mouse hepatitis virus (MHV), bovine coronavirus (BCV).Furthermore, the present invention also provides a recombinant coronavirus spike protein or a fragment thereof, which comprises a mutation to cysteine ​​at amino acid position 267, wherein the spike protein is selected from: infectious bronchitis virus (IBV); guinea fowl coronavirus (GfCoV), turkey coronavirus (TCoV; turkey enteritis virus and blue crown virus), feline infectious peritonitis virus (FIPV), feline enteric coronavirus (FECV); transmissible gastroenteritis virus (TGEV), porcine respiratory coronavirus (PRCoV), porcine epidemic diarrhea virus (PEDV), porcine hemagglutinating encephalomyelitis virus (PHEV); severe acute respiratory syndrome coronavirus (SARS-CoV), Middle East respiratory syndrome coronavirus (MERS-CoV), human coronavirus 229E (HCoV-229E), human coronavirus NL63 (HCoV-NL63), human coronavirus HKU1 (HCoV-HKU1), human coronavirus OC43 (HCoV-OC43); canine coronavirus (CCoV), canine respiratory coronavirus (CRCoV), mouse hepatitis virus (MHV), bovine coronavirus (BCV).

[0060] In another specific aspect of the avian coronavirus spike protein or its fragment according to the present invention, the avian coronavirus spike protein or its fragment is selected from: infectious bronchitis virus (IBV); guinea fowl coronavirus (GfCoV) and turkey coronavirus (TCoV; turkey enteritis virus and blue crown virus).

[0061] In another specific aspect of the avian coronavirus spike protein or fragment thereof according to the present invention, the avian coronavirus is IBV (infectious bronchitis virus).

[0062] 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.

[0063] The first IBV serotype identified was Massachusetts, and it remained the only serotype until the discovery of a different IBV serotype in 1956. Today, in addition to the originally identified Massachusetts type, several additional serotypes have been identified in the United States, including Arkansas and Delaware. Today, IBV Mass viruses can be identified in many countries around the world.

[0064] The IBV strain Beaudette is of the Massachusetts type and was derived after at least 150 passages in chicken embryos. 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 120 times in embryonated chicken eggs.

[0065] IBV QX is described as a virulent field isolate of IBV originally isolated in China. However, the virus has spread to Europe and has been identified in parts of Western Europe, primarily in the Netherlands, as well as 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.

[0066] The strain designated "Italien-02" or "Italy-02" was isolated in Italy in the late 1990s. 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, in addition to IBV variant 4 / 91, has become one of the most prevalent genotypes in the United Kingdom, Spain, France, and the Netherlands.

[0067] Since 1996, a new infectious bronchitis virus (IBV) genotype, designated Q1, has been circulating in China and was first reported in Italy in 2011. Q1 is associated with increased mortality, renal damage, and proventriculitis.

[0068] In addition, strains D274, B1648 / D8880, D1466, V1397, and Arkansas have been identified in Europe.

[0069] Where to obtain any IBV strain is within the general knowledge of those skilled in the art. IBV strains can be purchased commercially, obtained from scientific institutions, or the genome can be synthesized as complementary DNA, as IBV strains have been sequenced and the sequences are published and therefore available. In addition, IBV strains can be isolated from the wild. Methods for isolating and characterizing IBV strains are well known to those skilled in the art. Valter Leonardo deQuadros 2011 (Dissertation, Das Bronchitis Virus(IBV):Molekularbiologische Untersuchungen zur Diagnostik und zum Vorkommen sowiezur des Genotyps IBV QX in spezifisch pathogenfreien(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.

[0070] IBV strains are typically distinguished by the coding sequence of the S1 subunit of the spike protein (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 subunit 1 of the spike protein. Alternatively, IBV strains can be distinguished by their serotype. Serotyping involves serological determination of the virus, which involves serotype-specific antibodies.

[0071] In another specific aspect of the IBV spike protein or fragment thereof according to the present invention, the spike protein or fragment thereof is from an IBV having a genotype or serotype or strain selected from the following list: Arkansas (e.g., Arkansas 99), Brazil (e.g., BR-1, BR-2, 23 / 2013, IBV / Brasil / 351 / 1984), California (e.g., California 1734 / 04, California 99), Connecticut, Delaware (e.g., Delaware 98), Dutch (e.g., D207, D212, D274, D3128, D3896, D8880, D1466), Florida, Georgia (e.g., Georgia GA-07, GA-08, GA-12, GA-13), Gray, Holte, Iowa (e.g., Iowa 97 and Iowa 69), Italy02), JMK, LDT3, Maine (e.g., Maine 209), Massachusetts (e.g., M41, H52, H120; excluding Beaudette), Pennsylvania (e.g., Pennsylvania 1220 / 98, Pennsylvania Wolg / 98), PL84084, Qu (e.g., Qu-mv), QX (e.g., GB341 / 96), Q1, SE 17, variant 2 (e.g., IS / 1494 / 06, IBV / Ck / EG / CU / 4 / 2014, gammaCoV / Ck / Poland / G052 / 2016), and 4 / 91 (793B, CR88).

[0072] In another specific aspect of the IBV spike protein or fragment thereof according to the present invention, the spike protein or fragment thereof is not from the Beaudette strain.

[0073] In another specific aspect of the IBV spike protein or its fragment according to the present invention, the spike protein or its fragment is from an IBV selected from the following genotype or serotype or strain list: Massachusetts (not Beaudette), 4 / 91, QX, Q1, Italy 02, Arkansas, Conneticut, Georgia, LDT3, PL84084, variant 2 and Brazil.

[0074] The phrase "not Beaudette" is used to exclude Beaudette. Thus, the phrase "Massachusetts (not Beaudette)" means including spike proteins or fragments thereof from Massachusetts strains such as M41, H52, and H120, but excluding spike proteins or fragments thereof from the Beaudette strain.

[0075] In another specific aspect of the IBV spike protein or fragment thereof according to the present invention, the spike protein or fragment thereof is from an IBV selected from the following list of genotypes or serotypes: Massachusetts (not Beaudette), 4 / 91, QX, Q1, Arkansas, variant 2 and Brazil.

[0076] In another specific aspect of the IBV spike protein or fragment thereof according to the present invention, the spike protein or fragment thereof is from an IBV selected from the following list of genotypes or serotypes: Massachusetts (not Beaudette) and 4 / 91.

[0089] In another specific aspect of the IBV spike protein or fragment thereof according to the present invention, the IBV strain is H52, H120, QX SP2013-01478 or CR88.

[0090] In another specific aspect of the IBV spike protein or a fragment thereof according to the present invention, the IBV spike protein or a fragment thereof consists of or comprises: an amino acid sequence as shown in SEQ ID NO: 2, 3, 4, 5, 6, 7, 8, 77, or a sequence having at least 80%, 85%, 90%, 93%, 95%, 96%, 97%, 98%, 99%, 99.5%, 99.6%, 99.7%, 99.8%, 99.9%, 99.95%, 99.98% or 99.99% sequence identity thereto.

[0091] 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., a reference sequence and a given sequence to be compared to the reference sequence). Sequence identity is determined by comparing a given sequence to a reference sequence after the sequences have been optimally aligned to produce the highest degree of sequence similarity, as determined by matching between strings of such sequences. In such an alignment, sequence identity is determined on a position-by-position basis, e.g., if at a particular position, the nucleotides or amino acid residues are identical, the sequences are "identical" at that position. The total number of such positional identities is then divided by the total number of nucleotides or residues in the reference sequence to give the % 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 Math., 48:1073 (1988), the teachings of which are incorporated herein by reference. Preferred methods to determine sequence identity are designed to give the largest match between the sequences tested.Methods to determine sequence identity are codified in publicly available computer programs that determine sequence identity between given 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 available from NCBI and other sources (BLAST Manual, Altschul, S. et al., NCBI NLM NIH Bethesda, MD). 20894, Altschul, SF et al., J. Molec. Biol., 215:403-410 (1990), the teachings of which are incorporated herein by reference). These programs optimally align sequences using default gap weights to produce the highest level of sequence identity between a given sequence and a reference sequence. As an 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 is expected to be identical to the reference sequence. The same as above, except that a given polynucleotide sequence may include up to 15, preferably up to 10, even more preferably up to 5 point mutations per 100 nucleotides of the reference nucleotide sequence. In other words, in a polynucleotide having a nucleotide sequence that is at least 85%, preferably 90%, even more preferably 95% identical to a reference nucleotide sequence, up to 15%, preferably 10%, even more preferably 5% of the nucleotides in the reference sequence may be deleted or substituted by another nucleotide, or up to 15%, preferably 10%, even more preferably 5% of the total nucleotides in the reference sequence may be deleted or substituted by another nucleotide. nucleotides can be inserted into the reference sequence. These mutations of the reference sequence may occur at the 5' or 3' terminal positions of the reference nucleotide sequence or anywhere between these terminal positions, interspersed individually among nucleotides in the reference sequence or in one or more contiguous groups within the reference sequence. Similarly, a polypeptide having a given amino acid sequence that has at least, for example, 85%, preferably 90%, even more preferably 95% sequence identity to a reference amino acid sequence is expected to be identical to the reference sequence, except that the given polypeptide sequence may include up to 15, preferably up to 10, even more preferably up to 5 amino acid changes per 100 amino acids of the reference amino acid sequence. In other words, to obtain a given polypeptide sequence that has at least 85%, preferably 90%, even more preferably 95% sequence identity to a reference amino acid sequence, up to 15%, preferably up to 10%, even more preferably up to 5% of the amino acid residues in the reference sequence may be deleted or substituted with another amino acid, or a plurality of amino acids up to 15%, preferably up to 10%, even more preferably up to 5% of the total number of amino acid residues in the reference sequence may be inserted into the reference sequence.These changes in the reference sequence may occur at the amino or carboxyl terminal positions of the reference amino acid sequence or at any position between these terminal positions, individually interspersed among residues in the reference sequence or in one or more contiguous groups within the reference sequence. Preferably, residue positions that are not identical differ by conservative amino acid substitutions. However, conservative substitutions are not included as matches when determining sequence identity.

[0092] The terms "identity", "sequence identity" and "percentage identity" are used interchangeably herein. For the purposes of the present invention, it is defined herein that in order to determine the percentage identity of two amino acid sequences or two nucleic acid sequences, the sequences are compared for optimal comparison purposes (e.g., a gap can be introduced into the sequence of a first amino acid sequence or nucleic acid sequence for optimal comparison with a second amino acid sequence or nucleic acid sequence). The amino acids 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 percentage identity between the two sequences is a function of the number of equivalent positions shared by the sequences (i.e., % identity = the total number of the number of equivalent positions / positions (i.e., overlapping positions) x 100). Preferably, the two sequences have the same length.

[0093] Sequence comparison can be performed over the entire length of the two sequences to be compared or over a fragment of the two sequences. Typically, comparison is performed over the full length of the two sequences to be compared. However, sequence identity can be performed over a region of, for example, twenty, fifty, one hundred or more contiguous amino acid residues.

[0094] Those skilled in the art are aware of the fact that different computer programs can be used to determine the homology between two sequences. For example, comparison of sequences and determination of the percent identity between two sequences can be accomplished using a mathematical algorithm. In a preferred embodiment, the percent identity between two amino acid sequences 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 at http: / / www.accelrys.com / products / gcg / ), using a Blosum 62 matrix or a PAM250 matrix, and 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 person will appreciate that all of these different parameters will produce slightly different results, but the overall percent identity of the two sequences does not change significantly when different algorithms are used.

[0095] The protein or nucleic acid sequences of the present invention can further be used as a "query sequence" to search against 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) of Altschul et al. (1990) J. Mol. Biol. 215:403-10. BLAST protein searches can be performed with the BLASTP program, score = 50, word length = 3, to obtain amino acid sequences homologous to the protein molecules of the present invention. To obtain gapped alignments for comparison purposes, Gapped BLAST can be utilized as described in Altschul et al. (1997) Nucleic Acids Res. 25(17):3389-3402. When utilizing BLAST and Gapped BLAST programs, the default parameters of the respective programs (e.g., BLASTP and BLASTN) can be used.

[0096] As used herein, the term "sequence identical to SEQ ID NO: X" is specifically understood to be equivalent to the term "sequence identical to SEQ ID NO: X over the length of SEQ ID NO: X" or the term "sequence identical to SEQ ID NO: X over the entire length of SEQ ID NO: X," respectively. In this context, "X" is any integer selected from 1 to 84, such that "SEQ ID NO: X" represents any SEQ ID NO mentioned herein.

[0132] snippet

[0133] In another specific aspect of the avian coronavirus or IBV spike protein or fragment thereof according to the present invention, the fragment of the avian coronavirus or IBV spike protein has a length of at least 500, 750, 1000 or 1077 amino acids.

[0134] In another specific aspect of the avian coronavirus or IBV spike protein or fragment thereof according to the present invention, the fragment of the avian coronavirus or IBV spike protein has a length of at least 1000 amino acids.

[0135] In another specific aspect of the avian coronavirus or IBV spike protein or fragment thereof according to the present invention, the fragment of the avian coronavirus or IBV spike protein has a length of at least 500, 750, 1000 or 1075 amino acids from the N-terminus.

[0136] The term "N-terminus" is well known to those skilled in the art. The N-terminus is also known as the amino terminus, the NH2 terminus, the N-terminal end, or the 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).

[0137] In another specific aspect of the avian coronavirus or IBV spike protein or fragment thereof according to the present invention, the fragment of the avian coronavirus or IBV spike protein is the extracellular domain of the spike protein.

[0138] The term "extracellular domain" is well known to those skilled in the art. The spike protein comprises different functional parts, 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.

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 and promoted its protective effect. Furthermore, Wang et al. 2012 (Arch Virol (2012) 157:1451–1461) demonstrated results revealing the potential of chitosan as an adjuvant for use in live attenuated influenza vaccines.

[0216] 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 that can be used in the context of the present invention can be readily determined by the skilled person.

Emulsifiers are preferably nonionic surfactants, in particular sorbitan, mannide (e.g., anhydromannide oleate), ethylene glycol, polyglycerol, propylene glycol and esters of oleic acid, isostearic acid, ricinoleic acid or hydroxystearic acid, which are optionally ethoxylated, and polyoxypropylene-polyoxyethylene copolymer blocks, in particular Pluronic products, especially L 121. See Hunter et al., The Theory and Practical Application of Adjuvants (ed. Stewart-Tull, DES), John Wiley and Sons, NY, pp. 51-94 (1995), and Todd et al., Vaccine 15: 564-570 (1997). Exemplary adjuvants are the SPT emulsion described on page 147 of "Vaccine Design, The Subunit and Adjuvant Approach" edited by M. Powell and M. Newman, Plenum Press, 1995, and the emulsion MF59 described on page 183 of the same book.

[0218] A further 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 polymers of acrylic acid or methacrylic acid, especially cross-linked with polyalkenyl ethers of sugars or polyols. These compounds are known by the term carbomer (Phameuropa Vol. 8, No. 2, June 1996). Those skilled in the art can also refer to U.S. Patent No. 2,909,462, which describes such acrylic polymers cross-linked with polyhydroxylated compounds having at least 3 hydroxyls, preferably no more than 8 hydroxyls, wherein the hydrogen atoms of the at least three hydroxyls are replaced with unsaturated aliphatic radicals having at least 2 carbon atoms. Preferred radicals are those containing 2 to 4 carbon atoms, such as vinyl, allyl and other ethylenically unsaturated groups. The unsaturated radical itself may contain other substituents, such as methyl. Products sold under the name carbomer; (BF Goodrich, Ohio, USA) are particularly suitable. They are cross-linked with allyl sucrose or allyl pentaerythritol. Among them, mention may be made of carbomer 974P, 934P and 971P. Most preferred is the use of carbomer 971P. Among the copolymers of maleic anhydride and alkenyl derivatives is the copolymer EMA (Monsanto), which is a copolymer of maleic anhydride and ethylene. Dissolution of these polymers in water results in an acid solution that will preferably be neutralized to physiological pH in order to give an adjuvant solution into which the immunogenic composition, immunological composition or vaccine composition itself will be incorporated.

[0219] Further suitable adjuvants include, but are not limited to, the RIBI adjuvant system (Ribi Inc.), block copolymers (CytRx, Atlanta GA), SAF-M (Chiron, Emeryville CA), monophosphoryl lipid A, avridine lipid-amine adjuvant, heat-labile enterotoxin from Escherichia coli (recombinant or otherwise), cholera toxin, IMS 1314 or muramyl dipeptide, or naturally occurring or recombinant cytokines or analogs thereof, or stimulators of endogenous cytokine release, and the like.

[0276] Treatment

[0277] Further, the present invention provides methods for immunizing a subject comprising administering to such a subject an immunogenic composition as described herein.

[0278] The term "immunization" relates to active immunization by administering an immunogenic composition to the subject to be immunized, thereby eliciting an immune response against the antigens included in such immunogenic composition.

[0279] Preferably, the immunization results in a reduced incidence of, or a reduced severity of, clinical signs caused by or associated with, a specific avian coronavirus or IBV infection in a flock of birds.

[0280] Further, immunization of a subject in need thereof with an immunogenic composition as provided herein results in preventing the subject from infection with an avian coronavirus or IBV infection. Even more preferably, the immunization results in an effective, long-lasting immune response against 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 will be understood that the immunization may not be effective in all subjects immunized. However, the term requires that a significant proportion of the subjects in the flock be effectively immunized.

[0281] Preferably, in this context, a population of subjects is envisioned that would normally (i.e., if not immunized) develop clinical signs typically caused by or associated with infection with an avian coronavirus or IBV. Whether or not the subjects of said population have been effectively immunized can be readily determined by one skilled in the art. Preferably, immunization should be effective if the clinical signs are reduced by at least 10%, more preferably at least 20%, even 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% in the subjects of a given population compared to subjects who were not immunized or immunized with an immunogenic composition available prior to the present invention but subsequently became infected with a specific avian coronavirus or IBV.

[0282] Furthermore, the present invention provides a method for 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 or vaccine as described herein.

[0283] As shown in the Examples, the immunogenic compositions or vaccines provided herein have been shown to be effective in treating or preventing clinical signs caused by IBV in subjects. Thus, the experimental data show that modification of the amino acid at amino acid position 267 to cysteine ​​has no effect on the efficacy of the vaccine.

[0284] The term "treatment or prevention" refers to a reduction in the incidence of a specific IBV infection in a flock of birds, or a reduction in the severity of clinical signs caused by or associated with a specific IBV infection. Thus, the term "treatment or prevention" also refers to a reduction in the number of subjects in a flock of birds that become infected with a specific IBV (= a reduction in the incidence of a specific IBV infection), or a reduction in the severity of clinical signs typically associated with or caused by an IBV infection, or a reduction in viral shedding following infection with a specific IBV, or the prevention or reduction of a drop in egg production in laying hens following infection with a specific IBV, compared to a group of subjects whose subjects have not received such an immunogenic composition.

[0285] "Treatment or prevention" generally involves administering an effective amount of an immunogenic composition of the present invention to a subject or a group of subjects in need of or who may benefit from such treatment / prevention. The term "treatment" refers to the administration of 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 the administration of an effective amount of an immunogenic composition to a subject prior to any infection of such subject with IBV, or at least when none of the subjects in such subject or a group of subjects have shown any clinical signs caused by or associated with such IBV infection. The terms "prophylaxis" and "preventing" are used interchangeably in this application.

[0286] As used herein, the term "effective amount" means, 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 is capable of reducing the incidence of a specific IBV infection in a flock of birds, or reducing the severity of clinical signs of a specific IBV infection.

[0287] Preferably, clinical signs are reduced in incidence or severity by at least 10%, more preferably at least 20%, still more preferably at least 30%, even more preferably at least 40%, still more preferably at least 50%, even more preferably at least 60%, still more preferably at least 70%, even more preferably at least 80%, still more preferably at least 90%, still more preferably at least 95%, and most preferably 100%, compared to subjects who have not been treated or who have been treated with an immunogenic composition available prior to the present invention but who are subsequently infected with the particular IBV.

[0288] As used herein, the term "clinical signs" refers to signs of infection of a subject from 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, salpingitis, abnormal egg production, ruffled feathers, depression, reduced growth rate, and loss of appetite. Signs of respiratory distress include respiratory signs, including gasping, coughing, sneezing, tracheal rales, nasal and ocular discharge, tracheal damage, and ciliary arrest in the trachea. Signs of nephritis include kidney damage and watery diarrhea. Signs of abnormal egg production include decreased egg production, smaller eggs, inferior eggshells, reduced internal egg quality, eggs with thin albumen, and ciliary arrest in the oviduct. 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, reduced growth rate, decreased appetite, dehydration, watery diarrhea, lameness, lethargy, emaciation, and weakness.

[0289] Preferably, the clinical signs of reduced incidence or severity in treated subjects are reduced ciliary arrest, reduced rales, reduced egg production, reduced kidney damage, reduced watery diarrhea, reduced weight loss, lower viral load, reduced viral shedding, or a combination thereof, compared to subjects who are not treated or who are treated with an immunogenic composition available prior to the present invention but who are subsequently infected with a particular IBV.

[0290] As used herein, the term "in need of" or "in need of" means that the administration / treatment is associated with an enhancement or improvement of health or clinical signs, or any other positive medical effect on the health of the subject receiving the immunogenic composition according to the present invention.

[0291] Further, the present invention provides a method 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 or vaccine as described herein.

[0292] As shown in the Examples, the immunogenic compositions or vaccines as provided herein have been shown to be effective in reducing ciliary arrest.

[0293] The term "ciliostasis" refers to a decrease in ciliary motility in the trachea. Thus, ciliary motility can be determined by examining the lining of the tracheal rings for ciliary motility. How to determine ciliary motility in the trachea is within the general knowledge of a person skilled in the art.

[0294] Preferably, ciliary motility is not reduced starting from day 10 after challenge or infection with IBV, 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, compared to subjects in a non-immunized control group of the same species.

[0295] The term "reduction of ciliary arrest" means a reduction of 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 subjects of the same species. How to measure a reduction in ciliary arrest is within the general knowledge of a person skilled in the art.

[0296] Furthermore, the present invention provides an immunogenic composition or vaccine as described herein for use in a method of immunizing a subject, the method comprising administering to the subject a therapeutically effective amount of the immunogenic composition or vaccine.

[0297] Furthermore, the present invention provides an immunogenic composition or vaccine as described herein for use in 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 the immunogenic composition or vaccine.

[0298] Further, the present invention provides an immunogenic composition or vaccine as described herein for use in a method of reducing ciliary arrest in a subject in need thereof compared to a non-immunized control group of subjects of the same species, the method comprising administering to the subject a therapeutically effective amount of the immunogenic composition or vaccine.

[0299] In a specific aspect of the method or use according to the invention, the subject is a poultry.

[0302] The term "poultry" is well known to those skilled in the art. The term "poultry" includes chickens, turkeys, quail, pheasants, guinea fowl, geese and ducks. Further, the term "chicken" includes broilers, laying hens and breeding flocks for both, also known as breeders.

[0303] In a particular aspect of the method or use according to the invention, the subject is selected from chicken, turkey, quail or pheasant.

[0304] In a specific aspect of the method or use according to the invention, the subject is a chicken.

[0305] In a specific aspect of the method or use according to the invention, the immunogenic composition or vaccine is administered once.

[0306] It will be understood that a single dose is administered only once.As shown in the Examples, the immunogenic compositions as provided herein have been shown to be effective following administration of a single dose to a subject in need thereof.

[0307] The dose volume / bird depends on the route of vaccination and the age of the birds.

[0308] Typically, eye drop vaccines are administered at any age in a volume of 1 to 100 μl / dose. Preferably, a single dose of the eye drop vaccine has a total volume of about 5 μl to 70 μl, and more preferably about 20 μl to 50 μl, with a single 20 μl, 25 μl, 30 μl, 35 μl, 40 μl, 45 μl or 50 μl dose being preferred.

[0311] One dose of the vaccine for intramuscular or subcutaneous vaccination or the drinking water vaccine may contain a dose in a volume of 30 μl to 1000 μl. Preferably, a single dose has a total volume of about 30 μl to 1000 μl, more preferably about 50 μl to 500 μl, more preferably about 75 μl to 250 μl, and even more preferably about 100 μl to 200 μl, with a single 100 μl, 110 μl, 120 μl, 125 μl, 130 μl, 135 μl, 140 μl, 145 μl, 150 μl, 160 μl, 170 μl, 175 μl, 180 μl, 190 μl, 155 μl or 200 μl dose being most preferred.

[0312] In a particular aspect of the method or use according to the invention, the immunogenic composition or vaccine is administered in two or more doses.

[0313] However, the immunogenic composition may be administered in two or more doses, with a first dose being administered prior to a second (boost) dose.

[0314] In a preferred aspect 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, an alternative embodiment comprises further 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, with the time frame between doses being consistent with the time schedule between the first and second doses mentioned above.

[0315] Preferably, the first time of vaccine is used by the method as described below in the first three weeks of age, more preferably in the first week of age, and most preferably carried out in one-day age. The second time of use can be in the first 20 weeks of age, preferably in 16-18 weeks of age, more preferably carried out between 6-12 weeks of age. Exemplarily, initial (first time) vaccination is carried out when 1-10 days of age, and the second time vaccination (reinforcement) is carried out with live vaccine or inactivated vaccine when 6-12 or 16-18 weeks of age. More preferably, initial (first time) vaccination is carried out when one-day age, and the second time vaccination (reinforcement) is carried out with live vaccine or inactivated vaccine when 6-12 or 16-18 weeks of age.

[0316] Where in ovo vaccination is used, the first administration is preferably carried out when the embryo is 15 to 19 days old, preferably at 17, 18 or 19 days old, and most preferably at 18 days old. The second administration may be carried out within the first three weeks of age, preferably within the first 10 days of age.

[0317] In a specific aspect of the method or use according to the invention, the immunogenic composition or vaccine is administered subcutaneously, intramuscularly, orally, in ovo, via spray, via drinking water or by eye drops.

[0318] 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 suction, in an egg, via spray, via 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 intradermal, intravenous, intravascular, intraarterial, intraperitoneal, intrathecal, intratracheal, intradermal, intracardial, intralobar (intralobally), intralobular, intramedullary, intrapulmonary, rectal, and intravaginal. However, most preferably, the immunogenic composition is administered subcutaneously, intramuscularly, orally, in an egg, via spray, via drinking water or by eye drops.

[0319] The live IBV vaccine is preferably administered individually by eye drops, intranasally, intramuscularly or subcutaneously.

[0320] More preferably, a number of application methods are used, including drinking water and aerosol spray vaccination.Also preferred is the use of the vaccine as an embryonic vaccine (so called in ovo vaccine), as further described below.

[0321] For example, broiler chickens can be vaccinated at one day old or 1-3 weeks old, especially for broilers with high levels of MDA. Egg-laying or breeding flocks can be initially vaccinated at 1-10 days of age and boosted with the vaccine at 7-12 or 16-18 weeks of age.

[0322] In ovo administration

[0323] As outlined above, the present invention also provides an IBV vaccine that can be safely administered via the intra-ovo route and can simultaneously induce a protective immune response. In-ovo administration is well known to those skilled in the art, and those skilled in the art can effortlessly perform intra-ovo administration. In-ovo administration of the vaccine involves administering the vaccine to an avian embryo when contained in an egg (for a review of intra-ovo vaccination, see: Ricks et al., Advances in Vet. Med. 495-515, 1999). As described in the art (Sharma; Am. J. Vet. Res. 45 1619-1623, 1984), the vaccine can be administered to any suitable egg compartment (e.g., allantoic fluid, yolk sac, amniotic membrane, air chamber or embryo). Preferably, the vaccine is administered below the shell (air chamber) membrane and the chorioallantoic membrane.

[0324] Preferably, the vaccine is injected into embryonated eggs during the later stages of embryonic development, generally during the last quarter of the incubation period, preferably 3-4 days before hatching. Preferably, administration is performed when the embryo is 15 to 19 days old, preferably 17, 18 or 19 days old, and most preferably 18 days old. Subsequently, the vaccinated embryonated eggs are transferred to an incubator for hatching. The process of intra-ovo administration can be automated using a robotic injection process as described in the prior art.

[0325] Conventional vaccines used for post-hatching vaccination of poultry cannot be used for in ovo vaccination because late embryos are highly susceptible to infection by most vaccine viruses examined. However, International Patent Application WO 01 / 64244 discloses that an IBV vaccine can be used for in ovo administration, provided that it is administered at very low doses. Further, Wakenell et al. 1986 (Am. J. Vet. Res., 47 933-938) disclose that passage of an IB vaccine virus in tissue culture renders the virus apathogenic to the embryo.

[0326] In a particular aspect of the method or use according to the invention, the immunogenic composition or vaccine is administered via eye drops.

[0327] Typically, live vaccines for post-hatch administration contain 10 1 to 10 8 EID 50 (50% egg infectious dose) / dose concentration of attenuated IBV, preferably 10 2 to 10 5 EID 50 / dose concentration, and more preferably 10 2 to 10 4 EID 50 / unit dose concentration, and even more preferably at 10 2 to 10 3 EID 50 / dose concentration.

[0328] Live vaccines for in ovo administration typically contain 10 2 to 10 7 EID 50 / embryo, preferably 10 2 to 10 3 EID 50 / embryo attenuated IBV amount.

[0329] Preferably, the immunogenic composition of the present invention comprises an amount of about 1 to about 10 log 10 EID (Egg Infectious Dose) 50 / ml / dose of the IBV of the present invention, preferably from about 2 to about 8 log 10 EID 50 / dose, preferably from about 2 to about 7 log 10 EID 50 / dose amount, more preferably from about 2 to about 6 log 10 EID 50 / dose, even more preferably in an amount of about 2 to about 5 log 10 EID 50 / dose amount, even more preferably from about 2 to about 4 log 10 EID 50 / dose amount, most preferably about 2 to about 3 log 10 EID 50 More preferably, the immunogenic composition of the present invention comprises 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 10 EID 50 / dose of IBV of the present invention.

[0330] In a particular aspect of the method or use according to the invention, the immunogenic composition or vaccine comprises 1 to 10 log 10 EID 50 / dose of IBV.

[0331] In a particular aspect of the method or use according to the invention, the immunogenic composition or vaccine comprises 2 to 5 log 10 EID 50 / dose of IBV.

[0332] In a particular aspect of the method or use according to the invention, the immunogenic composition or vaccine comprises 2 to 4 log 10 EID 50 / dose of IBV.

[0333] In a specific aspect of the method or use according to the invention, the immunogenic composition or vaccine is administered to a subject within the first week of age, within the first three days of age, within the first two days of age or within the first day of age.

[0334] 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.

[0335] However, it must be understood that after vaccination of subjects at a few days of age, the immune system of poultry does require several days to build up immunity against IBV infection. Therefore, preferably, subjects are immunized within the first 24 hours of age.

[0336] In a specific aspect of the method or use according to the invention, the immunogenic composition or vaccine is administered to a subject within the first day of age. As shown in the Examples, the immunogenic composition as provided herein has been shown to be safe and effective when administered to 1 day old poultry.

[0337] In a specific aspect of the method or use according to 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 decreased egg production, prevention or reduction of kidney damage, prevention or reduction of watery diarrhea, prevention or reduction of weight loss, lower viral load, reduced viral shedding, or a combination thereof, compared to subjects in an untreated control group of the same species.

[0338] The terms "treatment and / or prevention" have been defined elsewhere, wherein the terms "prophylaxis" and "preventing" or "prevention" are used interchangeably in this application. Further, the term "shedding" has also been defined elsewhere.

[0339] The terms "reducing," "reduced," "reduction," or "lowering" mean that the efficacy parameter (ciliostasis, rales, decreased egg production, kidney damage, watery diarrhea, weight loss, viral load, viral shedding) is reduced 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 an unimmunized control group of the same species. How to measure the improvement of an efficacy parameter is within the general knowledge of those skilled in the art.

[0340] The term "viral load" or "viral titer" is a measure of the severity of an active viral infection and can be determined by methods well known to those skilled in the art. The term "viral titer" is a measure of the viral preparation of infection units / volume. Viral titer is the endpoint in a biological procedure and is defined as the dilution at which a certain proportion of tests performed in parallel show an effect (Reed and Muench, 1938). Determination can be based on, for example, viral protein detection by antibodies bound to viral proteins, and further detection or alternative detection by amplification methods such as RT-PCR viral RNA detection. Monitoring the virion-related viral RNA in blood plasma by nucleic acid amplification methods is a widely used parameter to evaluate the state and progression of retroviral diseases, and to assess the effectiveness of preventive interventions and therapeutic interventions. Exemplarily, viral load or viral titer can be calculated by estimating the viral activity in the body fluids involved, for example, the RNA copy number per milliliter of blood plasma.

[0341] The term "ciliostasis" is well known to those skilled in the art.
