Prevalence, serodiagnosis and histopathological changes in field cases of infectious bronchitis in chickens

Infectious bronchitis (IB) is an acute highly contagious viral disease of respiratory and urogenital system of chickens affecting both broilers and layers. Present studies suggested that HA and HI tests are more superior, inexpensive, sensitive and rapid for identification of Infectious Bronchitis Virus (IBV) as compared to AGPT. The necropsy and histopathological examination indicated the involvement of nephropathogenic avian IBV.
