Escherichia coli ( / ˌɛʃəˈrɪkiə ˈkoʊlaɪ / ESH-ə-RIK-ee-ə KOH-ly) [1] [2] is a gram-negative, facultative anaerobic, rod-shaped, coliform bacterium of the genus Escherichia that is commonly found in the lower intestine of warm-blooded organisms. [3] [4] Most E. coli strains are harmless, but some serotypes such as EPEC, and ETEC are ...

Escherichia coli (E. coli) is a bacterium that is commonly found in the gut of humans and warm-blooded animals. Most strains of E. coli are harmless. Some strains however, such as Shiga toxin-producing E. coli(STEC), can cause severe foodborne disease. It is transmitted to humans primarily through consumption of contaminated foods, such as raw or u...
Symptoms of the diseases caused by STEC include abdominal cramps and diarrhoea that may in some cases progress to bloody diarrhoea (haemorrhagic colitis). Fever and vomiting may also occur. The incubation period can range from 3 to 8 days, with a median of 3 to 4 days. Most patients recover within 10 days, but in a small proportion of patients (par...
Most available information on STEC relates to serotype O157:H7, since it is easily differentiated biochemically from other E. colistrains. The reservoir of this pathogen appears to be mainly cattle. In addition, other ruminants such as sheep, goats, deer are considered significant reservoirs, while other mammals (such as pigs, horses, rabbits, dogs...
The prevention of infection requires control measures at all stages of the food chain, from agricultural production on the farm to processing, manufacturing and preparation of foods in both commercial establishments and household kitchens.
WHO provides scientific assessments to control STEC in food. These assessments serve as the basis for international food standards, guidelines, and recommendations developed by the Codex Alimentarius Commission. WHO promotes the strengthening of food safety systems by promoting good manufacturing practices and educating retailers and consumers abou...

Escherichia coli. (Migula 1895) Castellani and Chalmers 1919. Escherichia coli or E. coli is a bacterium that lives in the intestines [1] 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.
Oct 1, 2022 · Symptoms. Signs and symptoms of E. coli O157:H7 infection usually begin three or four days after exposure to the bacteria. But you may become ill as soon as one day after exposure to more than a week later. Signs and symptoms include: Diarrhea, which may range from mild and watery to severe and bloody. Stomach cramping, pain or tenderness.
Oct 1, 2022 · Escherichia coli (E. coli) bacteria normally live in the intestines of healthy people and animals. Most types of E. coli are harmless or cause relatively brief diarrhea. But a few strains, such as E. coli O157:H7, can cause severe stomach cramps, bloody diarrhea and vomiting. You may be exposed to E. coli from contaminated water or food ...
