副溶血弧菌(即致病性嗜盐菌——译者)作为食物中毒的病原菌已引起了全世界的注意,每年都有死亡病例报告。为了阐明其致死原因,作者对该菌毒素进行了研究,其结果如下;将副溶血弧菌的液体培养物离心沉淀,其上清液中,存在致死活性物质(致死毒素),业已证明这种耐热性溶血毒素,就是与副溶血弧菌病原性有密切关系的引起神奈川现象阳性的物质。该耐热性溶血毒素的理化特性如下:能耐热100℃10分钟;可被胃蛋白酶、α-糜蛋白酶和 Nagarse 等消化;在 pH7.0时,
Vibrio parahaemolyticus, a pathogenic strain of food poisoning, has drawn worldwide attention and reports of deaths every year. In order to elucidate its cause of death, the authors studied the mycotoxin, the results of which are as follows; a liquid culture of Vibrio parahaemolyticus is centrifuged, and the supernatant contains the lethal active (lethal toxin), which has been shown Heat-resistant hemolytic toxin, which is closely related with the pathogenic Vibrio parahaemolyticus cause positive Kanagawa substances. The heat-resistant hemolytic toxin physical and chemical properties are as follows: heat-resistant 100 ℃ 10 minutes; pepsin, α-chymotrypsin and Nagarse digestion; at pH 7.0,
