Enterotoxigenic Escherichia coli (five strains) and Yersinia enterocolitica (five strains) were cultivated in sterile milk at 22 and 4 degrees C. The bacteria grew well at both temperatures. Three strains of E. coli produced heat-labile enterotoxin in the milk at 22 degrees C as demonstrated by enzyme-linked immunosorbent assay. Heat-stable enterotoxins were not detected in milk by the infant mouse test.
产肠毒素大肠杆菌(五株)和小肠结肠炎耶尔森菌(五株)在无菌牛奶中于22℃和4℃下培养。两种温度下细菌均生长良好。通过酶联免疫吸附测定表明,三株大肠杆菌在22℃的牛奶中产生不耐热肠毒素。通过幼鼠试验在牛奶中未检测到耐热肠毒素。
