Enteropathogenic E. coli (EPEC) causative agent of diarrhea in humans, rabbits, dogs, cats and horses Watery Like ETEC, EPEC also causes diarrhea, but the molecular mechanisms of colonization and aetiology are different. EPEC lack ST and LT toxins, but they use an adhesin known as intimin to bind host intestinal cells.
E. coli is a bacterium that is normally found in the human intestine, but some strains of bacteria can cause illness and infection. [ citation needed ] Subgroups of diarrheagenic Escherichia coli (DEC) are the following: enteroinvasive E. coli (EIEC), enteropathogenic E. coli (EPEC), enterotoxigenic E.coli (ETEC), Shiga toxin-producing E. coli ...
Enterotoxigenic E. coli (ETEC) produces a toxin that acts on the intestinal lining, and is the most common cause of traveler's diarrhea. Enteropathogenic E. coli (EPEC) can cause diarrhea outbreaks in newborn nurseries. Enteroaggregative E. coli (EAggEC) can cause acute and chronic (long-lasting) diarrhea in children.
E. coli is a gram-negative, facultative anaerobe, nonsporulating coliform bacterium. [18] Cells are typically rod-shaped, and are about 2.0 μm long and 0.25–1.0 μm in diameter, with a cell volume of 0.6–0.7 μm 3. [19] [20] [21] E. coli stains gram-negative because its cell wall is composed of a thin peptidoglycan layer and an outer membrane.
[2] [failed verification] The ones that do are collectively known as enterohemorrhagic E. coli (EHEC) and are major causes of foodborne illness. When infecting the large intestine of humans, they often cause gastroenteritis , enterocolitis , and bloody diarrhea (hence the name "enterohemorrhagic") and sometimes cause a severe complication ...
Enterotoxigenic Escherichia coli (ETEC) is a type of Escherichia coli and one of the leading bacterial causes of diarrhea in the developing world, [1] as well as the most common cause of travelers' diarrhea. [2] Insufficient data exists, but conservative estimates suggest that each year, about 157,000 deaths occur, mostly in children, from ETEC.

Intimin is a virulence factor of EPEC (e.g. E. coli O127:H6) and EHEC (e.g. E. coli O157:H7) E. coli strains. It is an attaching and effacing (A/E) protein, which with other virulence factors is necessary and responsible for enteropathogenic and enterohaemorrhagic diarrhoea.
