An Escherichia coli intestinal infectious disease that involves infection of the intestine caused by a serological subgroup of Escherichia coli called enteropathogenic Escherichia coli (EPEC), which has a plasmid-encoded protein referred to as EPEC adherence factor that enables localized adherence of bacteria to intestinal cells and a non fimbrial adhesin designated intimin, which is an outer membrane protein that mediates the final stages of adherence. EPEC induce a profuse watery (sometimes bloody) diarrhea.
