The incidence of Escherichia coli EPEC and ETEC had been studied on 555 infants from Tunis area. 193 of them do not present any diarrhea. Frequency of EPEC is 9.14% in infants with diarrhea and 3.10% in the group without diarrhea. Analysis of 87 Escherichia coli strains using genetic probes showed that 4 EPEC strains present effacing attachment factor (EAF) and one EPEC strain produce verotoxin. The frequency of ETEC isolated is 18.05%, the majority of them produced ST enterotoxin. Only colonization factor antigen I (CFAI) was found in ETEC strains.
对突尼斯地区555名婴儿的大肠杆菌肠致病性大肠杆菌（EPEC）和肠产毒性大肠杆菌（ETEC）发病率进行了研究。其中193名婴儿未出现任何腹泻症状。腹泻婴儿中EPEC的发生率为9.14%，无腹泻组为3.10%。使用基因探针分析87株大肠杆菌菌株，结果显示4株EPEC菌株具有紧密黏附素（EAF），1株EPEC菌株产生志贺毒素。ETEC的分离率为18.05%，其中大多数产生ST肠毒素。在ETEC菌株中仅发现定居因子抗原I（CFAI）。
