Virus neutralization study using H120, H52, 793/B antisera against Iranian infectious bronchitis virus genotypes.

This study is aimed to investigate the neutralizing efficiency of H52, H120, and 4/91 antiserum against IBV genotypes (IS-1494, IS-720, 793/B, IR-1) recently circulating in Iran. For the first time, we have used cross-neutralization tests for the serological classification of these isolates. In this study, all antisera failed to neutralize all IBV strains. According to the results of our research, cross-protection studies are necessary for the design of a proper vaccination program for IBV circulating genotypes in Iran. The data are useful for the development of new vaccine strategies. Keywords: avian infectious bronchitis; Iran; virus neutralization. PMID: 30472866 [PubMed - in process]
