Infectious bronchitis virus (IBV) is prevalent in all countries with an intensive poultry industry, with the incidence of infection approaching 100% in most locations. Vaccination is only partially successful due to the continual emergence of antigenic variants. At many sites, multiple antigenic types are simultaneously present, requiring the application of multiple vaccines. Although many coun...

BACKGROUND: Avian infectious bronchitis is considered as an important viral disease worldwide. Genotyping based on the S1 subunit of spike protein gene of the causative agent, avian infectious bronchitis virus, can be used to classify IBV isolates. Objective: This survey was carried out to characterize the infectious bronchitis virus (IBV) genotypes circulating in Iran and determine their preva...
