Overview
E. coli enteritis may be classified according to the E. coli strain pathogenesis into Enterotoxigenic E. coli (ETEC), Enteropathogenic E. coli (EPEC), Enterohemorrhagic E. coli (EHEC), and Enteroinvasive E. coli (EIEC).
Classification
E. coli enteritis may be classified according to the involved E. coli strain into the following:
- Enterotoxigenic E. coli - ETEC
- Enteropathogenic E. coli - EPEC (including diffusely adherent E. coli (DAEC), a subtype of EPEC)
- Enterohemorrhagic E. coli - EHEC
- Enteroinvasive E. coli - EIEC
The following table demonstrates the distinguishing clinical features and pathophysiological mechanisms of various enteritis-causing E. coli strains:
| Properties/Symptoms | ETEC | EPEC | EHEC | EIEC |
| Toxin | LT/STa | - | Shiga or Vero toxin | - |
| (Stx or VT) | ||||
| Invasive | - | - | - | + |
| Intimin | - | + | + | - |
| Enterohemolysin | - | - | + | - |
| Stool | Watery | Watery, Bloody | Watery, very bloody | Mucoid, bloody |
| Fever | Low | + | - | + |
| Fecal leukocytes | - | - | - | + |
| Intestine involved | Small | Small | Colon | Colon, lower small |
| Serology | Various | O26, O111 & others | O157:H7, O26, O111 & others | Various |
| IDb | High | High | Low | High |
a=LT, labile toxin; ST, stable toxin; b=ID, infective dose.
