A bacterium commonly found in faeces.
A genus of Gram-negative, generally motile, rod-like bacteria that have the ability to ferment carbohydrates, usually with production of gas, and are found in the intestines of man and many animals. E. coli, a lactose-fermenting species, is usually not harmful but under certain conditions can cause infection of the urogenital tract and diarrhea in children. It is also widely used in laboratory experiments for bacteriological and genetic studies.
The generic name for the group of gram-negative, usually motile, rod-shaped bacteria that can ferment carbohydrates. They occur naturally in the intestines of humans and some animals. E. coli, which ferments lactose, is not normally harmful but some varieties, particularly E. coli 0157, cause gastrointestinal infections which may be severe in old people. E. coli is also used in laboratory experiments for genetic and bacteriological research.
A genus of gram-negative, motile, facultatively anaerobic, non-spore-forming bacilli of the family Enterobacteriaceae. These bacteria are part of the normal flora of the intestines of humans and animals.
