一般描述
葡萄球菌肠毒素A属于葡萄球菌外毒素家族。它由金黄色葡萄球菌分泌，后者是一种革兰氏阳性菌。
应用
在TRANSIA检测试剂盒、RIDASCREEN检测试剂盒和Vidas Set 2方法的验证中，已使用来自金黄色葡萄球菌的葡萄球菌肠毒素A作为外标。用于小鼠脾细胞的体外毒素刺激。
通过给小鼠腹腔注射来自金黄色葡萄球菌的葡萄球菌肠毒素A诱导败血症。10
生化/生理作用
来自金黄色葡萄球菌的葡萄球菌肠毒素A是引起食物中毒的主要病原体。浓度低至0.5 mg/ml就足以导致恶心、呕吐、腹泻和痉挛。8 它能刺激外周血淋巴细胞的增殖，诱导干扰素的产生，对抵抗金黄色葡萄球菌感染的肠道免疫具有重要作用。9 它是T淋巴细胞的超级抗原。
