Milk and cold meat samples were contaminated with 7 various serogroups of Yersinia enterocolitica strains. The infected food samples were incubated under different conditions of growth, at different temperatures and for different periods of time, then the number of colony forming units was determined and enterotoxin production was assayed by the suckling mice test. The Y. enterocolitica strains multiplied well under varying conditions of growth, but enterotoxin production could be detected only in the meat samples when incubated under shaking at 25 degrees C for 48 h. It may be assumed that performed yersinia enterotoxin is absent from food stored under normal conditions.
牛奶和冷肉样本被7种不同血清群的小肠结肠炎耶尔森菌菌株污染。将受感染的食物样本在不同的生长条件下、不同温度和不同时间段进行培养，然后测定菌落形成单位数量，并通过乳鼠试验检测肠毒素的产生。小肠结肠炎耶尔森菌菌株在不同生长条件下繁殖良好，但仅在25摄氏度振荡培养48小时的肉样本中检测到肠毒素的产生。可以推测，在正常储存条件下的食物中不存在已产生的耶尔森氏肠毒素。
