Isolation, Identification and Antimicrobial Susceptibility of Avibacterium Paragallinarum from Backyard Chicken in Retail Markets of Karaj and Tehran Cities, Iran.

ABSTRACT: Avibacterium (Haemophilus) Paragallinarum (Av. Paragallinarum) is the causative agent of Infectious Coryza (IC) in chickens. Despite the worldwide distribution of IC, no systematic study, to the best of our knowledge, was conducted on isolation and characterization of Av. Paragallinarum in Iran. The present study aimed to isolate and perform antibacterial susceptibility testing (AST) of IC agents from suspected backyard chickens with typical symptoms of IC in avian markets. From 18 collected choanal swab samples, four (22%) isolates of Av. Paragallinarum were detected by culture methods based on satellite growth on blood agar, which was confirmed by the biochemical reaction of Catalase and Oxidase tests and species-specific PCR (HPG-2).
