What is an E. coli infection?
E. coli (Escherichia coli) is the name of a germ, or bacterium, that lives in the digestive tracts of humans and animals.
There are many types of E. coli, and most of them are harmless. But some can cause bloody diarrhea. Some strains of E. coli bacteria may also cause severe anemia or kidney failure, which can lead to death.
Other strains of E. coli can cause urinary tract infections or other infections.
