Samples from chickens and pork sausages were examined for the presence of Vero cytotoxin-producing Escherichia coli by using DNA probes for the Vero cytotoxin genes. Hybridization was detected in 25% of the 184 sausage samples, but none of the chickens was positive. No E. coli O157:H7 strains were isolated, and serotyping showed that the Vero cytotoxin-producing E. coli strains belonged to eight different O serogroups and that six strains had an unidentifiable O antigen.
通过使用针对志贺毒素基因的DNA探针,检测了鸡肉和猪肉香肠样本中是否存在产志贺毒素大肠杆菌。在184份香肠样本中,25%检测到杂交信号,但所有鸡肉样本均为阴性。未分离出大肠杆菌O157:H7菌株,血清分型显示产志贺毒素大肠杆菌菌株属于8个不同的O血清群,且有6株菌株的O抗原无法鉴定。
