Strains of Escherichia coli which belong to enteropathogenic serogroups usually fail to produce heat-labile or heat-stable enterotoxins. However, 1 of 34 strains of E. coli O44, 9 of 45 strains of E. coli O114, and 18 of 82 strains of E. coli O128 produced heat-labile or heat-stable enterotoxins. Most enterotoxigenic isolates were from tropical or developing countries; all three enterotoxigenic strains isolated in Britain were from patients returned from abroad. Enterotoxigenic strains were of many different flagellar types. Certain enterotoxigenic strains of E. coli O114 and O128 possessed colonization factor antigen I.
属于肠道致病性血清群的大肠杆菌菌株通常不产生不耐热或耐热肠毒素。然而,34株大肠杆菌O44中有1株、45株大肠杆菌O114中有9株以及82株大肠杆菌O128中有18株产生了不耐热或耐热肠毒素。大多数产肠毒素分离株来自热带或发展中国家;在英国分离出的3株产肠毒素菌株均来自从国外返回的患者。产肠毒素菌株有许多不同的鞭毛类型。某些大肠杆菌O114和O128的产肠毒素菌株具有定居因子抗原I。
