对近年来本市分离的金黄色葡萄球菌进行肠毒素检测与分析

Detection and analysis of enterotoxin in Staphylococcus aureus isolated from Suzhou city in recent years

目的:了解分离于四类不同样品的97株金黄色葡萄球菌携带肠毒素的情况。方法:采用mini VI-DAS酶联荧光免疫分析仪对此97株金黄色葡萄球菌进行肠毒素的检测。结果:97株菌中,有39株菌能产肠毒素,阳性率为40.2%,其中,分离自即食类食品的25株被测菌中,有17株肠毒素阳性,阳性率达68.0%。结论:食品样品中分离的金黄色葡萄球菌产肠毒素的阳性率较高,具有引发急性胃肠炎等食物中毒的潜在危害。

Objective：To survey the distribution of enterotoxin in 97 Staphylococcus aureus isolated from four types of samples. Methods ： Enterotoxin was detected in 97 Staphylococcus aureus samples by mini VIDAS detector. Results： Of the 97 strains of. Staphylococcus aureus , 39 strains can produce enterotoxin, the positive rate was 40.2%, among them, 17 enterotoxin strains were separated from 25 ready -to -eat food samples, the positive rate was 68.0%. Conclusion： Higher positive rate of enterotoxigenic Staphylococcus aureus was found in food samples, which would lead to the potential hazards of acute gastroenteritis and food poisoning.
