| 摘 要： | 金黄色葡萄球菌肠毒素是一种热源性的超抗原。食用被肠毒素污染的食物能够引起食物中毒，导致恶心、呕吐、腹痛有时伴随腹泻。本文综述了肠毒素的分类命名、理化性质、以及编码不同肠毒素的基因在移动基因元件中的存在情况。这些移动基因元件在金黄色葡萄球菌毒力传播和进化过程中起着至关重要的作用，了解它们对于金黄色葡萄球菌流行病学溯源以及理解毒力机制具有一定的指导意义。

| Abstract: | Staphylococcal enterotoxins (SEs) belong to the family of pyrogenic toxin superantigens. The consumption
of foods containing SEs could cause food poisoning with the symptoms of nausea, vomiting, abdominal cramping, and
diarrhea. This review summarizes the classification and physicochemical properties of different SEs, especially focusing
on the mobile genetic elements encoding SEs, which would have a theoretical and practical significance to epidemiological
investigation and understanding of the virulence mechanism of Staphylococcus aureus enterotoxins. |

| Keywords: | Staphylococcus aureus staphylococcal enterotoxins (SEs) physicochemical properties mobile genetic elements |
