The jejunal and stool flora of children with gastroenteritis in London and in Jamaica was examined. Although bacterial colonization of the small bowel was commonly detected, it was unusual to find the same serotype of E. coli in both jejunum and stool, and none of the jejunal strains of E. coli produced either heatlabile or heat-stable enterotoxin. Some strains of E. coli causing infant gastroenteritis are neither toxigenic nor invasive, and other mechanisms must be sought to account for their pathogenicity.
对伦敦和牙买加患肠胃炎儿童的空肠和粪便菌群进行了检查。虽然小肠细菌定植普遍被检测到,但在空肠和粪便中发现相同血清型的大肠杆菌并不常见,而且空肠中的大肠杆菌菌株均不产生热不稳定或热稳定肠毒素。一些导致婴儿肠胃炎的大肠杆菌菌株既不产毒素也不具侵袭性,必须寻找其他机制来解释它们的致病性。
