A normal bacterial resident of the large intestine.
One of the members of the coliform groups of bacteria indicating fecal contamination. (See fecal, coliform.)
A species of bacterium. E. coli is a motile, gram negative, rod-shaped bacterium. It is a normal inhabitant of the large intestine of humans and other mammals. It crowds out disease-causing bacteria and makes vitamin K. The toxic strains of this microbe are responsible for a number of diseases, including many incidences of traveler's diarrhea. The mutant strain, O157:H7, that has recently been in the news for contaminating undercooked beef from several fast-food establishments, is very dangerous, causing hemorrhagic colitis.
A coliform (see separate entry) which indicates the presence of faeces in water.
A type of common bacteria normally found in the colon. Some strains that cause diarrhoea are acquired during travel.
A rod-shaped bacterium belonging to the same family as Salmonella. E. coli is of the coliform group, which are organisms associated with the intestinal tract flora. Presence of coliforms is usually an indication of unsanitary handling or processing procedures.
(E. coli) A common bacterium that has been studied intensively by geneticists because of the small size of its genome, the organism's normal lack of pathogenicity, and its ease of growth in the laboratory.
Most common coliform bacteria; the usual cause of prostatitis.
Bacteria that cause infection and irritation of the large intestine. The bacteria are spread by unclean water, dirty cooking utensils, or undercooked meat. See also gastroenteritis.
(E. coli) A common eubacterial resident of the human gut.
a Gram-negative bacterium commonly found in the human colon, the most thoroughly studied of all bacteria, frequently used in recombinant bacterial fermentation.
( E. coli): Rodlike bacterium normally found in the colon of humans and other mammals and widely used in biomedical research.
A common gut bacterium used as a model genetic organism. E. coli has about 3,000 genes and a genome of around 4 million basepairs.
are bacteria commonly used in research. The strain we use is not the same as the strain which causes disease.
( E. coli) - A type of coliform bacteria present in the gastrointestinal tract of warm-blooded animals. The concentration of E. coli bacteria is an indicator of the probability of contamination of surface water by microbial pathogens. Reported in Colony Forming Units/100 mL of sample (CFU/100 mL).
A Gram negative, rod-shaped bacterium which inhabits the lower intestines of most mammals. Because it grows at a wide range of temperatures with minimal nutrient requirements, it is the bacterium of choice for studies in genetics, biochemistry and molecular biology. In addition, E. coli has yielded a wide variety of restriction endonucleases including EcoRI, EcoRI', EcoRII, EcoB, EcoK, EcoPI, and EcoPI5. Although E. coli is ubiquitous among humans, some strains of this bacterium do cause human disease.
a pathogenic, fecal bacteria. Presence in pool or spa water at infectious levels may be the result of inadequate sanitation, gross contamination or poor water management.
a species of bacterium normally present in intestinal tract of humans and other animals; sometimes pathogenic; can be a threat to food safety
bacterium normally found in the large intestine in humans, where it maintains health of the intestine and makes vitamin K.
A bacteria which is not usually harmful but under certain conditions can cause infection and diarrhoea in children.
Escherichia coli is a strain of harmless bacteria that live in the intestines of healthy humans and animals. However, the O157:H7 strain, transmitted through improperly prepared infected meat or contact with infected feces, produces a powerful toxin that can cause severe illness.
Coliform bacterium that is often associated with human and animal waste and is found in the intestinal court. It is used by health departments and private laboratories to measure the purity of water.
short, rod-shaped microorganisms accounting for most of our gut microorganisms.
bacterium commonly associated with a wide range of infections, including bladder infections and diarrhoea.
A specific coliform bacteria used as an indicator organism of pathogens in fecal coliform testing.
A bacteria that can cause infection of the large intestine. E. coli is found in rare or undercooked meat, and can also be spread by using dirty cooking utensils or through contaminated water.
A bacterium that inhabits the intestinal tract of most vertebrates. Much of the work using recombinant DNA techniques has been carried out with this organism because it has been genetically well characterized.
a typically harmless bacteria that is found in the human digestive tract and is present in fecal material. E. coli 0157: H7 is a pathogenic strain transmitted most commonly by undercooked meats, raw milk and person-to-person contact. This strain may cause bloody diarrhea and can lead to hemolytic uremic syndrome, a rare but occasionally fatal kidney disorder.
a common bacterium found in fecal matter; member of the coliform group
A gram-negative, facultatively anaerobic, nonspore-forming bacillus commonly found in the intestinal tracts of humans and other warm-blooded animals. In sanitary bacteriology, Escherichia coli is considered the primary indicator of recent fecal pollution.
Bacteria found in the human gut that are quite popular as a simple model organism in biological research. Taxonomy: Bacteria; Proteobacteria; gamma subdivision; Enterobacteriaceae; Escherichia
a common gut bacteria that is a workhorse and model organism for molecular biology.
Full term for E. coli, the colon bacillus. See the entire definition of Escherichia coli
The bacteria commonly used as a host cell for cloning segments of genomic DNA.
a bacterium found in the intestine of animals and humans used extensively in genetic engineering. E. coli can be fatal to humans if undercooked meat is digested.
a species of bacteria commonly occurring as part of the normal intestinal flora in humans. Click here to view two electronmicrographs. For more information, What the Heck is an E. Coli ? is a good source. Click to view a Swimming E. coli.
Common bacterium found in human and mammalian digestive tracts. Some strains of E. coli are used in recombinant DNA work because they have been genetically well-characterized and are easily grown in laboratory fermenters.
One of the members of the coliform bacteria group normally found in human and animal intestines and indicative of fecal contamination when found in water. Determination of whether E. Coli is present is often used to measure the microbiological safety of drinking water supplies. (See fecal, coliform.)
Escherichia coli (IPA: ) (E. coli), is one of the main species of bacteria living in the lower intestines of mammals, known as gut flora. Discovered in 1885 by Theodor Escherich, a German pediatrician and bacteriologist, E. coli are abundant: the number of individual E. coli bacteria in the feces that a human excretes in one day averages between 100 billion and 10 trillion. However, the bacteria are not confined to this environment, and specimens have also been located, for example, on the edge of hot springs.
