Enterotoxin-producing Staphylococcus aureus is a common cause of staphylococcal food poisoning. To determine the incidence of carriage of enterotoxin-producing S. aureus in a sample of the healthy population in Kuwait city, restaurant workers in the city were screened for nasal carriage of S. aureus. 26.6% of 500 workers studied carried S. aureus and 86.6% of the S. aureus produced staphylococcal enterotoxins. 28% produced enterotoxin A, 28.5% produced enterotoxin B, 16.4% produced enterotoxin C and 3.5% produced enterotoxin D. Ten isolates produced both enterotoxins A and B or A and C. 73% of the isolates were untypeable with standard phages. However, 17.1%, 3% and 6% belonged to phage groups I, II and III respectively. The results demonstrated a high level of enterotoxigenic S. aureus carriage among restaurant workers which although lower than that reported for the general population and hospital workers may be important in the restaurant industry.
产肠毒素金黄色葡萄球菌是葡萄球菌食物中毒的常见病因。为确定科威特城健康人群样本中产肠毒素金黄色葡萄球菌的携带率，对该市餐厅工作人员进行了金黄色葡萄球菌鼻腔携带情况筛查。在研究的500名工作人员中，26.6%携带金黄色葡萄球菌，其中86.6%的金黄色葡萄球菌产生葡萄球菌肠毒素。28%产生肠毒素A，28.5%产生肠毒素B，16.4%产生肠毒素C，3.5%产生肠毒素D。10株分离株同时产生肠毒素A和B或A和C。73%的分离株不能用标准噬菌体分型。然而，17.1%、3%和6%分别属于噬菌体Ⅰ组、Ⅱ组和Ⅲ组。结果表明，餐厅工作人员中产肠毒素金黄色葡萄球菌的携带率较高，尽管低于普通人群和医院工作人员的报告率，但在餐饮行业可能具有重要意义。
