This is very different from enteric bacilli, which normally reside in the human GI tract and do not cause disease under normal circumstance. Though enteric bacilli may causes disease outside of the GI tract (such as the urinary tract or blood stream), they are native to the human GI tract and often beneficial. Enteric pathogens are usually spread by contamination of food or by people who carry them on the skin or elsewhere. They are common nosocomial pathogens (spread in healthcare settings). Enteric pathogens are transmitted often by the "fecal-oral" route.
