Abstract Background Infectious bronchitis is highly contagious and constitutes one of the most common and difficult poultry diseases to control. IBV is endemic in probably all countries that raise chickens. It exists as dozens of serotypes genotypes. Only a few amino acid differences in the si protein of vaccine and challenge strains of IBV may result in poor protection. Tropism of IBV includes the respiratory tract tissues proventriculus and caecal tonsils of the alimentary tract the oviduct and the kidney. Results Infectious bronchitis virus IBV strain closely related to Massachusetts Mass serotype was isolated from broiler chickens suffering from severe renal and respiratory .
