The trophozites (active form) are present only in the host and fresh loose faeces. E. coli is found in the faeces of the carrier. In unsanitary conditions (like open defecation), the cysts are released and they may be persistent for a few months in the environment. When a person drinks untreated water contaminated with E. coli, the cysts enter his digestive system. once inside the digestive system, the cysts release the trophozite stage within the digestive tract which may lead to further infection. the trophozites are generally present in the large intestine. Sometimes, they invade the intestinal mucosa, enter the blood stream and pass on to the different parts of the body causing a number of outcomes, the most common of which is liver abcess.
