Infectious coryza is a highly contagious bacterial disease caused by Avibacterium paragallinarum. Total 5 samples were collected from different birds suspected for infectious coryza based on clinical signs like nasal discharge, conjunctivitis, face swelling and post mortem examination which revealed caseous or cheesy exudates in infra orbital sinus. Nasal swabs, eye swabs from live birds and infra orbital sinus cavity exudates from dead birds were collected on separate sterile cotton swabs. Cultural examination of peritoneum revealed E.coli infection with characteristic greenish metallic shiny colonies on EMB agar. The swabs collected from nasal passage and infra orbital sinus were subjected to PCR for confirmation of the disease and the samples were positive for Avibacterium paragallinarum.
