Overview
E. coli enteritis may be classified according to the E. coli species into Enterotoxigenic E. coli (ETEC), Enteropathogenic E. coli (EPEC), Enterohemorrhagic E. coli (EHEC), Enteroinvasive E. coli (EIEC), and Enteroaggressive E. coli (EAEC).
Classification
E. coli enteritis may be classified according to the involved E. coli species listed as follows:
- Enterotoxigenic E. coli (ETEC)
- Enteropathogenic E. coli (EPEC) (including diffusely adherent E. coli [DAEC], a subtype of EPEC)
- Enterohemorrhagic E. coli (EHEC) (may be Shiga-like toxin producing or Verotoxin-producing)
- Enteroinvasive E. coli (EIEC)
- Enteroaggressive E. coli (EAEC)
The following table demonstrates the distinguishing clinical features and pathophysiological mechanisms of various enteritis-causing E. coli strains:
| Properties/Symptoms | ETEC | EPEC | EHEC (STEC or VTEC) |
EIEC |
| Toxin | LT/STa | - | Shiga or Vero toxin | - |
| 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.
