Genetic and immunological characterization of commercial infectious bronchitis virus vaccines used in Korea

We compared the S1 gene sequences of three IBV vaccines commercially available in Korea with those of various field isolates to examine this problem. According to a phylogenetic review, the vaccine strains clustered into two distinct lineages. The most of the genetic variation was found in hypervariable regions, according to a comparison of commercial vaccines with their parental viruses. Immunogenes and host immune responses can be affected by genetic variation, according to our review.
