Staphylococcus aureus is gram positive, facultatively anaerobic, non-sporulative coccus, and positive for coagulase and DNase. The food oisoning outbrealc of Staphylococcus aureus increases in the world, and third occurnn happened in our country. Of 105 isolates (25.4%) obtained 413 fecal samples of food-poisoning suspicious patients. In those cases, the enterotoxins were detected firom a total of 45 isolates (42.9%), 9 isolates(20.0%) were A type, 33 isolates (73.3%) we H types, 2 isolates (4.4%) were G type and 1 isolate was a I type enterotoxin. Among the isolates possessing staphylococcal enterotoxins, 29 isolates had H type only(64.4%), 5 isolates had A type only and 4 isolates had both A and H type. 'Iieo isolates had G type only and 1 isolate had I type only. In the antibiotic susceptibility, 48 isolates (46%) had at least one antibiotic resistance among 105 isolates, 34 isolates (70.8%) were resistant to penicillin, 1 isolate (2.1%) to ampicillin, 3 isolates (6.3%) to erythromycin and kanamycin. Seven were resistant to more than two antibiotics and especially 1 isolate was resistant to penicillin-ampicillin-nitrofurantoin.
