Baby mouse and Y1 cell culturing tests were conducted into 117 Escherichia (E.) coli strains from mastitis of cattle to clear up enterotoxin formation. The rate of the latter was found to be relatively low, with enterotoxins recorded from only 7 strains (6%). No correlations were established between enterotoxin formation, on the one hand, and antibiotic resistance as well as biochemical activities of E. coli isolates, on the other. The question still remains open, if enterotoxin-forming strains derive their udder pathogenicity from endotoxins or with support by enterotoxins.
对117株来自奶牛乳腺炎的大肠杆菌进行了幼鼠和Y1细胞培养试验，以确定肠毒素的形成情况。发现后者的发生率相对较低，仅7株（6%）记录到肠毒素。一方面，肠毒素的形成与大肠杆菌分离株的抗生素耐药性和生化活性之间未建立相关性。产肠毒素菌株的乳房致病性是源于内毒素还是由肠毒素支持，这个问题仍然悬而未决。
