serological survey for detection of avian infectious bronchitis virus antibodies in domestic village chickens in Esfahan, central Iran

ABSTRACT

Infectious bronchitis [1B] is a very contagious disease caused by a coronavirus [IBV]. In chickens, the virus affects the respiratory, reproductive, and urinary systems. This study was carried out to determine the seroprevalence of anti-IBV antibodies in domestic village chickens. Serum samples of 300 domestic village chickens from Esfahan [centeral Iran] were collected and examined for the presence of anti-lBV antibodies by commercial ELISA kits. The results showed that 85.3% of the domestic village chickens had high titers of anti-IBV antibody without any clinical signs. It was concluded that the rate of IBV infection in these chickens is very high that could be a potential hazard for commercial poultry
