Enterotoxin production by atypical Staphylococcus aureus from poultry

Phenotypically typical Staphylococcus aureus was isolated frequently from the necrotic bone and liver of poultry suffering from femoral head necrosis. Occasionally strains were isolated that differed from typical Staph. aureus in one or more of the major diagnostic tests, i.e. coagulase production,...

Summary:Phenotypically typical Staphylococcus aureus was isolated frequently from the necrotic bone and liver of poultry suffering from femoral head necrosis. Occasionally strains were isolated that differed from typical Staph. aureus in one or more of the major diagnostic tests, i.e. coagulase production, anaerobic fermentation of mannitol and production of a heat-stable deoxyribonuclease. Such atypical strains were also isolated from nasal swabs of healthy birds. Tests for enterotoxin production demonstrated that some atypical strains from both sick and healthy birds are capable of producing staphylococcal enterotoxins.
