Inactivated vaccine against Infectious Coryza – Avibacterium paragallinarum-serotypes A, B & C – in Oil Emulsion

Infectious Coryza

Infectious coryza is an acute respiratory disease of chickens characterized by nasal discharge, facial swelling and anorexia. The causative agent of infectious coryza is Avibacterium paragallinarum. The disease occurs worldwide and causes economic losses due to an increased number of culls and a marked (10% to more than 40%) drop in egg production, particularly on multi-age farms. Prevention with vaccines is the only method of control.
