A bacterium found in the intestine of animals and humans Used extensively in genetic engineering Some strains can cause disease, the majority are harmless
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
(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)
(ess-chair-ee-chee-a koe-lie) O157: H7; an emerging cause of foodborne illness; 73,000 cases of infection and 61 deaths occur in the US annually (est ); often leads to bloody diarrhea, and occasionally to kidney failure; most often associated with eating undercooked, contaminated ground beef; person-to-person contact in families and child care centers also modes of transmission; may occur after drinking raw milk and after swimming in or drinking sewage- contaminated water
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
Principal member of the faecal coliforms group; it is almost always found in human faecal matter It can then be considered an indication of pollution of faecal origin There are different strains of E coli, including the O157: H7 EHEC, which causes intenal bleeding
(E coli): 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
Common bacterium that has been studied intensively by geneticists because of its small genome size, normal lack of pathogenicity, and ease of growth in the laboratory
O157Foodborne bacteria that cause the human illness, E coli O157 disease Eighty-five percent of the 73,480 annual U S illnesses from this bacteria are from contaminated food (such as ground beef)
a rod shaped bacteria commonly found in the gastrointestinal tract and feces of warm blooded animals It is a member of the fecal coliform group of bacteria and is distinguished from them by its inability to break down urease The addition of urea substrate confirms that colonies are E coli This bacteria is a preferred indicator for freshwater recreational waters and its presence provides direct evidence of fecal contamination from warm blooded animals Although usually harmless, E coli can cause illnesses such as meningitis, septicemia, urinary tract, and intestinal infections A recently discovered strain of E coli (E coli 0157: H7) can cause severe disease and may be fatal in small children and the elderly
One of the species of Coliform bacteria found in the intestinal tract of warm-blooded animals Its presence is considered indicative of fresh fecal contamination
