Escherichia coli, more commonly known as E. coli, is a group of bacteria that populate the human (and animal) gut. E. coli is usually thought of as a good bacterium; it lives in the intestines as part of the normal gut flora.. However, some strains of E. coli can cause very serious illness. These disease-causing (virulent) strains are usually classified by the action they have on the gut; these strains include enterohemorrhagic (called EHEC), enteropathogenic (called EPEC), enteroinvasive (called EIEC), and enterotoxigenic (ETEC).
