- A commensal bacterium inhabiting the colon of many animal species, including human. E. coli is widely used as a model of cell biochemical function, and as a host for. In environmental studies, its presence is a key indicator of water pollution due to human sewage effluent. Some strains, notably E. coli 0157:H7, are significant pathogens.
