Typical and atypical enteropathogenic Escherichia coli

Luiz R Trabulsi et al. Emerg Infect Dis. 2002 May.

Abstract

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.
