Preparation and use of an autogenous bacterin against Infectious Coryza in chickens.

Adherence to and colonization of the encapsulated variant on the nasal mucosa seems to be a first step of infection Sawata et al. In layers infection causes a drop in egg production; in broilers there may be an increased need to cull birds Bains, In this study, there was a strong association between the isolation of A.

Specimens should be taken from two or three chickens in the acute stage of the disease. At the simplest level, IC may be diagnosed on the basis of a history of a rapidly spreading disease in which coryza is the main manifestation.
