Typical and atypical enteropathogenic Escherichia coli (EPEC) strains differ in several characteristics. Typical EPEC, a leading cause of infantile diarrhea in developing countries, is rare in industrialized countries, where atypical EPEC seems to be a more important cause of diarrhea. For typical EPEC, the only reservoir is humans; for atypical EPEC, both animals and humans can be reservoirs. Typical and atypical EPEC also differ in genetic characteristics, serotypes, and virulence properties. Atypical EPEC is more closely related to Shiga toxin-producing E. coli (STEC), and like STEC these strains appear to be emerging pathogens.
典型和非典型肠致病性大肠杆菌(EPEC)菌株在几个特征上有所不同。典型EPEC是发展中国家婴儿腹泻的主要原因,在工业化国家较为罕见,在这些国家非典型EPEC似乎是腹泻更重要的病因。对于典型EPEC,唯一的宿主是人类;对于非典型EPEC,动物和人类都可能是宿主。典型和非典型EPEC在遗传特征、血清型和毒力特性方面也存在差异。非典型EPEC与产志贺毒素大肠杆菌(STEC)关系更为密切,并且与STEC一样,这些菌株似乎是新出现的病原体。
