Bacteria in Humans
Escherichia coli (E. coli) bacteria normally live in the intestines of healthy people and animals and are usually harmless or may cause relatively brief diarrhea. Few particular strains, such as E. coli O157:H7, can cause severe abdominal cramps, bloody diarrhea and vomiting.
You can 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).
Many of us host a population of E. coli in our gut that aids digestion and protects us from other harmful microbes. They aren't all bad.
