Abstract :

Pseudomonas aeruginosa is the most common avian pathogens can cause localized or systemicdiseases in young and growing poultry. Morbidity and mortality varies from 2 to 100%, butmore commonly about 2-12% with greatest losses in very young birds. The disease occurred in6-10 days-old ross broiler chickens. Clinical signs showed sleepy appearance, closed eyes, mildkeratitis and catarrhal rhinitis. Gross lesions revealed airsacculitis, congestion and swollen ofkidneys with deposition of ureats in the urters and proctitis. The disease morbidity and mortalityrates were 16.2% and 6%, respectively. Microbial culture was determined motile and Gramnegativebacteria, suspected greenish colonies, smell like fruity and beta hemolysis on bloodagar. Consequently, we suspected to Pseudomoniasis after culture and clinical signs finding.These isolates were transmitted to the department of microbiology, faculty of veterinarymedicine, university of Tehran and all isolates were identified by microbiological phenotypiccharacteristics with conventional methods and Pseudomonas aeruginosa was finally diagnosed.
