Classification

Escherichia coli pathotypes associated with disease in animals

Pathogenic E. coli, have been grouped into broad classes, or pathotypes, based on the mechanisms by which they cause disease. The following are the most important pathotypes in animals.

Escherichia coli pathotypes
ETEC	Enterotoxigenic Escherichia coli
STEC	Shiga toxin producing Escherichia coli
AEEC	Attaching and effacing Escherichia coli
ExPEC	Extraintestinal Escherichia coli
UPEC	Uropathogenic Escherichia coli
APEC	Avian pathogenic Escherichia coli
