Abstract

Out of 165 Staphylococcus species isolated from milk and cheese samples, 49 isolates (32 from milk and 17 from cheese) were identified as S. aureus strains. Among the 49 S. aureus strains examined, 35 (71·4%) produced one or more enterotoxin. Most strains (21 strains) produced only one type of enterotoxin of which type C was predominant. In vitro incubation of liver slices of cow and buffalo with enterotoxin C 2 resulted in a significant inhibition of protein and RNA synthesis in a dose-dependent manner. The maximum inhibition of protein and RNA synthesis was obtained at a dose of 5 μg enterotoxin.
