EPEC

Definition

Enteropathogenic Escherichia coli (EPEC) are a type of pathogenic E. coli that cause diarrhea, primarily in infants. They attach to the intestinal lining and disrupt normal microvilli function.

5 Must Know Facts For Your Next Test

1. EPEC do not produce toxins like some other pathogenic E. coli strains.
2. They adhere to intestinal cells using bundle-forming pili (BFP).
3. EPEC disrupts the intestinal cell surface by forming attaching and effacing lesions.
4. Common symptoms of EPEC infection include watery diarrhea and vomiting.
5. EPEC is typically diagnosed through stool cultures and PCR testing.
