In a randomly selected population, 2,008 fecal samples were screened for presence of Verotoxin producing Escherichia coli (VTEC) by colony sweep polymyxin-B extraction method. Non-sorbitol fermentation (NSF) phenotype and slide agglutination with O157: H7 antisera were used for screening and detection of this serotype. Ninety-eight (4.9%) fecal samples were found to be VTEC-positives and none of them belonged to the O157: H7 serotype. In rural areas, most individuals carrying VTEC isolates were asymptomatic, whereas in urban areas, a significant association was found between VTEC isolation and diarrhoea (p < 0.01).
在一个随机选取的人群中，采用菌落扫描多粘菌素B提取法对2008份粪便样本进行了产志贺毒素大肠杆菌（VTEC）检测。非山梨醇发酵（NSF）表型和用O157:H7抗血清进行玻片凝集试验用于该血清型的筛查和检测。发现98份（4.9%）粪便样本为VTEC阳性，且均不属于O157:H7血清型。在农村地区，大多数携带VTEC菌株的个体无症状，而在城市地区，发现VTEC分离与腹泻之间存在显著关联（p<0.01）。
