With increasing interest in verocytotoxigenic Escherichia coli (VTEC) being associated with both human and animal infection, a simple system of rapidly identifying the majority of VTEC has been devised. This depends on the fact that most VTEC produce enterohaemolysin, which is rarely produced by non-VTEC. By employing two media, traditional sheep blood agar (SBA) and washed sheep blood agar supplemented with calcium (WSBA-Ca), enterohaemolysin-producing strains can be easily differentiated from other E. coli enabling most VTEC types, including ones belonging to serogroups other than O157, to be isolated.
随着人们对产志贺毒素大肠杆菌（VTEC）与人类和动物感染之间关系的兴趣日益增加，已设计出一种快速鉴定大多数VTEC的简单系统。这取决于以下事实：大多数VTEC产生肠溶血素，而非VTEC很少产生这种物质。通过使用两种培养基，即传统的绵羊血琼脂（SBA）和补充钙的洗涤绵羊血琼脂（WSBA-Ca），可以轻松地将产生肠溶血素的菌株与其他大肠杆菌区分开来，从而能够分离出大多数VTEC类型，包括属于O157以外血清群的菌株。
