Infectious coryza

Infectious coryza is an acute respiratory disease characterized by nasal discharge, sneezing, and swelling of the face under the eyes.
It is found worldwide.
The disease is seen only in chickens.
The causative bacterium is Avibacterium paragallinarum, a Gram-negative and nonmotile bacteria.
In the mildest form of infectious coryza, the only signs may be depression, a serous nasal discharge, and slight facial swelling.
In the more severe form, there is pronounced swelling of one or both infraorbital sinuses with oedema of the surrounding tissues. This oedema may close one or both eyes.
