Escherichia coli

Escherichia coli or E. coli is a bacterium that lives in the intestines of people and other warm-blooded animals. Scientists have studied E. coli a lot, and know more about how E. coli cells work than any other organism. E. coli is usually not harmful. In fact, the only known harmful strain is O156. E.coli is a prokaryotic organism.

E. coli normally grow in soil and in the large intestines of many mammals, including humans. Most strains of E. coli do not cause disease, but instead help animals get vitamins and digest food. Some strains of E. coli cause sickness in people. E. coli are not usually in food or water. When food has not been prepared with clean equipment, E. coli can grow in the food. When E. coli are found in water, this may mean that the water has touched sewage. 

E. coli has been divided into pathogenic strains causing many diseases.  It can cause intestinal, urinary tract or internal infections and pathologies, when it comes to animals or humans.  

It is named after Theodor Escherich, who discovered it in 1885. It was officially named after him in 1919.
