E. coli — Comprehensive overview covers symptoms, complications, treatment of this common foodborne illness.
definition
DefinitionEscherichia coli (E. coli) bacteria normally live in the intestines of healthy people and animals. Most varieties of E. coli are harmless or cause relatively brief diarrhea. But a few particularly nasty strains, such as E. coli O157:H7, can cause severe abdominal cramps, bloody diarrhea and vomiting.
You may be exposed to E. coli from contaminated water or food — especially raw vegetables and undercooked ground beef. Healthy adults usually recover from infection with E. coli O157:H7 within a week, but young children and older adults can develop a life-threatening form of kidney failure called hemolytic uremic syndrome (HUS).

* Diarrhea, which may range from mild and watery to severe and bloody
* Abdominal cramping, pain or tenderness
* Nausea and vomiting, in some people
