The production of enterotoxin A and B by strains of Staphylococcus aureus isolated from nasal swabs of healthy carriers, from lesions of hospital patients and from foods unconnected with outbreaks of food-poisoning was investigated. Sixty-six strains of S. aureus were obtained from human beings, two produced enterotoxin A, 45 produced enterotoxin B, seven produced enterotoxins A + B. Thirty-six strains were isolated from 111 samples of food, one produced enterotoxin A, 16 produced enterotoxin B. The relative incidence of A, B and A + B enterotoxigenicity was assessed.
对从健康带菌者的鼻拭子、医院患者的病灶以及与食物中毒暴发无关的食品中分离出的金黄色葡萄球菌菌株产生A和B型肠毒素的情况进行了调查。从人类身上获得了66株金黄色葡萄球菌，其中2株产生A 型肠毒素，45株产生B型肠毒素，7株产生A + B型肠毒素。从111份食品样本中分离出36株，其中1株产生A 型肠毒素，16株产生B型肠毒素。评估了A、B和A + B型产肠毒素性的相对发生率。
