Abstract: Attenuated isolates of avian reoviruses associated viral arthritis/tenosynovitis in poultry are presented, including avian reovims strain 94826 C140 deposited at the ATCC under Patent Designation PTA-126077 and progeny or derivatives thereof and avian reovims strain 96139 C140 deposited at the ATCC under Patent Designation PTA-126078 and progeny or derivatives thereof. Compositions and methods for administering the isolates or compositions as vaccines to control of reovims-induced viral arthritis/tenosynovitis in birds of the order Galliformes are also presented.

Abstract: The present invention relates to novel strains of avian reovirus that were isolated from clinical cases of viral arthritis/tenosynovitis in chickens in the southeast United States. The invention is directed to these novel group 1 and group 2 avian reoviruses, diagnostic assays using antibodies and/or nucleotide- or amino acid-specific components of such viruses, such as the S1 gene encoding the sigma C protein, and to vaccines that protect chickens from disease caused by such viruses.

Abstract: The present invention includes isolated astroviruses capable of reproducing the full Runting Stunting Syndrome (RSS) disease spectrum in poultry, including a chicken astrovirus isolated from the gut of chickens (CkAstV-Gut), a cell culture chicken astrovirus CkAstV-p5, and a chicken astrovirus isolated after back passage in chicken (CkAstV-p5-Ckp5), and infected cell lines, cell culture supernatants, polynucleotide sequences, vectors, polypeptides, compositions, and vaccines thereof. The present invention also includes diagnostic methods based on such isolated viruses and infected cell lines, cell culture supernatants, polynucleotide sequences, vectors, and polypeptides thereof, and methods of protecting poultry, including chickens, against RSS by the administration of such isolated viruses and infected cell lines, cell culture supernatants, polynucleotide sequences, vectors, polypeptides, compositions, and vaccines thereof.

Abstract: The present invention includes polypeptides, polynucleotides, antibodies, and vaccines associated with Runting Stunting Syndrome (RSS) in poultry. The present invention also includes diagnostic methods based on such polypeptides, polynucleotides, and antibodies and methods of protecting poultry, including chickens, against RSS by the administration of such polypeptides, polynucleotides, antibodies, and vaccines.

Abstract: The present invention provides materials and methods for researching poultry viruses, particularly for researching infectious bronchitis viruses in poultry. Also provided are materials and methods useful for reducing the economic impact that infectious bronchitis disease has on poultry production. In one aspect of the invention, there are provided nucleic acids, amino acids and related materials and compositions useful for combating infectious bronchitis virus in poultry.

Abstract: The present invention relates to novel strains of avian reovirus isolated from severe cases of Runting Stunting Syndrome in young broiler chickens in southeast United States. The invention is directed to avian reoviruses that impair digestion in poultry, diagnostic assays using nucleotide- or amino acid-specific components of such viruses, and to vaccines that protect chickens from disease caused by such viruses. Nucleotide sequences for the S1 gene, encoding the sigma C minor outer capsid protein, were amplified, and the nucleotide and predicted amino acid sequences were compared with sequences from other recently isolated reovirus field isolates and vaccine strains. Antigenic and molecular characterization of the newly isolated reoviruses revealed a lack of homogeneity with current U.S. isolates, with less than 60% percent amino acid similarity across the sigma C protein.

The invention is directed to avian reoviruses that impair digestion in poultry, diagnostic assays using nucleotide- or amino acid-specific components of such viruses, and to vaccines that protect chickens from disease caused by such viruses. Nucleotide sequences for the SI gene, encoding the sigma C minor outer capsid protein, were amplified, and the nucleotide and predicted amino acid sequences were compared with sequences from other recently isolated reovirus field isolates and vaccine strains. Antigenic and molecular characterization of the newly isolated reoviruses revealed a lack of homogeneity with current U.S. isolates, with less than 60% percent amino acid similarity across the sigma C protein.
