Abstract excerpt
The major immunogenic protein VP2 from a pathogenic field isolate (variant A virus) of infectious bursal disease virus (IBDV) was cloned and sequenced to examine antigenic variations. The VP2 open reading frame consists of 1509 nucleotides and codes for a 503 amino acid protein. Overall, the VP2 amino acid sequence of the variant A virus shares 98.6% identity with VP2 genes from other published IBDV strains....
