Escherichia coli (/ˌɛʃᵻˈrɪkiə ˈkoʊlaɪ/; also known as E. coli) is a Gram-negative, facultatively anaerobic, rod-shaped bacterium of the genus Escherichia that is commonly found in the lower intestine of warm-blooded organisms (endotherms). Most E. coli strains are harmless, but some serotypes can cause serious food poisoning in their hosts, and are occasionally responsible for product recalls due to food contamination. The harmless strains are part of the normal flora of the gut, and can benefit their hosts by producing vitamin K2, and preventing colonization of the intestine with pathogenic bacteria.E. coli is expelled into the environment within fecal matter. The bacterium grows massively in fresh fecal matter under aerobic conditions for 3 days, but its numbers decline slowly afterwards.
E. coli and other facultative anaerobes constitute about 0.1% of gut flora, and fecal–oral transmission is the major route through which pathogenic strains of the bacterium cause disease. Cells are able to survive outside the body for a limited amount of time, which makes them potential indicator organisms to test environmental samples for fecal contamination. A growing body of research, though, has examined environmentally persistent E. coli which can survive for extended periods outside of a host.
E.coli is a bacterium that is commonly found in the gut of all humans and most warm-blooded animals. Most strains of E.Coli have beneficial functions. For example they may prevent harmful bacteria from establishing themselves in the intestine. There are some strains of E.Coli, however, that are pathogenic, which means that they can cause diseases.
This bacteriology lecture will explain the general properties of Escherichia coli and it also explains the disease, pathogenesis, and treatment of E.coli infection.

E. coli are a large and diverse group of bacteria. Although most strains of E. coli are harmless, others can make people sick. Some kinds of E. coli can cause diarrhea, while others cause urinary tract infections, respiratory illness and pneumonia, and other illnesses. Still other kinds of E. coli are used as markers for water contamination.
Escherichia coli, commonly abbreviated E. coli, is a gram negative bacilli often found as normal flora in the intestines.

Most E. coli strains are harmless and considered an important part of a healthy human intestinal tract. But the one behind the Chipotle cases, known as STEC 026, is a different story. Here's what you need to know.
