摘要
为利用肠出血性大肠杆菌(EnterohaemorrhagicEscherichiacoli,EHEC)琼脂平板,从食物中分离、检测产志贺毒素大肠杆菌(shigatoxin-producingEscherichiacoli,STEC),采用STEC毒力基因(hlyA基因)检测溶血素的产生,建立了一种利用EHEC琼脂平板快速、准确地从食物中分离、检测STEC的方法。该方法可检测STEC不同血清O157∶H7、O26、O111。
In order to isolation and detection of shiga toxin-producing Escherichia coll (STEC) in foods using Enterohaemorrhagic Escherichia coli (EHEC) agar plate. The enterohaemolysin producing was detected by means of toxicity gene hlyA of STEC. A rapid method of isolation and detection STEC in foods using EHEC agar plate was established. The method may detection three serotypes (O157:H7, O26, O111) of STEC.
