Abstract
Decades after its discovery, the infectious bursal disease virus (IBDV) still poses significant risks in poultry industry, due to its immunosuppressive effect on afflicted animals. This study aims to determine the different genotypes of IBDV that are present in the country, through molecular characterization and phylogenetic analysis of the VP2 hypervariable domain of infectious bursal disease virus. Nested RT-PCR was used to confirm the presence of IBDV in samples collected from 10 farms. Subsequent genetic analysis through nucleotide sequencing and phylogenetic analysis revealed the presence of three (3) variants in Luzon broiler farms. The variant IBDV was found to be the most dominant strain with seven (7) out of the ten (10) isolates bearing similar genetic characteristics. The analysis of the different strains of IBDV is intended to inform farm veterinarians of the presence of the variant IBDV, which necessitates the following changes on vaccination protocols and husbandry in the farm.
