Abstract
Poultry production is an important sector of agriculture in Sri Lanka; however, there is a lack of information regarding circulation of infectious bronchitis virus (IBV). RNA was extracted from chicken tissues, subjected to IBV S1 RT-PCR, and sequenced. Overall, 19 out of 34 (55.88%) samples were IBV positive and contained the genotype 793B (n=13; 68.42%), D274 (n=4; 21.05%) or Massachusetts (n=2; 10.53%). All three genotypes contained at least one strain with less than 99% nucleotide sequence identity to the corresponding vaccine strains. This report identified co-circulation of IBV strains 793B, Massachusetts and D274, in Sri Lanka that are divergent from the respective vaccine strains.
