  • The present study was conducted to investigate the prevalence, the biochemical properties and the enterotoxin types of Staphylococcus aureus in healthy human and patient. A total of 61 S. aureus strains were isolated from 142 samples. The prevalence of S. aureus isolated from healthy human and patient were 17.7% and 14.0%, respectively. All the isolates showed the production of coagulase, lecithinase and hemolysis (${\alpha}-hemolysis;\;32.8%,\;{\beta}-hemolysis;\;67.2%$) on sheep blood agar. Coagulase type VII (38.4%) and type 111 (26.0%) were dominant among coagulase types I through VIII. Twenty-four (52.2%) of 46 strains tested produced one or more enterotoxin; enterotoxin A, Band C were produced by 3, 9 and 12 strains, respectively. Enterotoxins were produced by 100% of type 11 strains, 75% of type 111 and 39.1 % of type VII. Commonly, coagulase type II produced enterotoxin B or C, and type VII produce enterotoxin C.
