Observations on Salmonella infections of birds.

During the period 1961 to 1976, 29 species of Salmonella other than Salmonella pullorum were isolated from 180 accessions of birds examined at the Animal Research Institute, Yeerongpilly. These birds were submitted to the laboratory from flocks with disease or production problems. S. typhimurium was the most frequently isolated serotype being obtained from 63% of accessions. Outbreaks of systemic salmonellosis occurred most frequently in young birds and although pathological changes were most commonly observed in visceral organs they were also seen in eyes, joints and the brain. Diseases other than salmonellosis were identified in many accessions of birds with systemic or enteric salmonella infections.
