Pseudomonas aeruginosa infection on a broiler farm

Pseudomonas aeruginosa infection was a factor associated with heavy losses on a broiler farm. The organism was repeatedly isolated from air sac lesions similar to those commonly observed in E.coli complicated Chronic Respiratory Disease, and from oedematous lesions present predominantly in the head region of some of the affected chickens. Losses continued in successive batches of chickens until an all-in all-out policy was adopted, although the organism was still present in the drinking water.
