描述

Infectious coryza is an acute respiratory disease of chickens caused by Avibacterium
paragallinarum. It is characterized by nasal discharge, facial swelling, conjunctivitis,
and reduced feed and water intake, leading to poor growth and egg production. The
disease spreads rapidly through direct contact and aerosols. Control involves strict
biosecurity, antibiotic therapy, and vaccination in endemic areas.
