E. coli is the name of a type of bacteria that lives in your intestines and in the intestines of animals. Although most types of E. coli are harmless, some types can make you sick. The worst type of E. coli, known as E. coli O157:H7, causes bloody diarrhea and can sometimes cause kidney failure and even death. E. coli O157:H7 makes a toxin called Shiga toxin and is known as a Shiga toxin-producing E. coli (STEC). There are many other types of STEC, and some can make you just as sick as E. coli O157:H7. One severe complication associated with E. coli infection is hemolytic uremic syndrome (HUS).
