Staphylococcus aureus isolated from poultry in Australia. II. Epidemiology of strains associated with tenosynovitis.

Bacteriophage typing of Staphylococcus aureus from different outbreaks of tenosynovitis in broiler breeder replacement chickens showed that, although a mixture of phage types was present on affected farms, there was a predominant phage type isolated from lesions of affected chickens. The predominant phage type isolated from chickens in different outbreaks was variable. The source of S. aureus associated with tenosynovitis appeared to be a resident population present on the skin.
