  • STEC
  • Food-poisoning outbreaks due to Shiga-toxin-producing E. coli (STEC) are typically the result of transmission via raw or undercooked ground meat (thought to become contaminated during slaughter or processing) or contaminated salad ingredients. (thefreedictionary.com)
  • Genome
  • Publication of the Entire E. coli (K12) genome was completed in 1997 by Blattner, Plunkett and colegues. (prezi.com)
  • 1997. The complete genome sequence of Escherichia coli K-12. (prezi.com)
  • Escherichia coli contains a number of small RNAs located in intergenic regions of its genome. (wikipedia.org)
  • The homepage of MicrobesOnline is the portal for accessing its functions, which includes six main sections: the top navigation elements, a genome selector, examples of the tutorial based on E.coli K-12, a link to the Genome-Linked Application for Metabolic Maps (GLAMM), website highlights and the "about MicrobesOnline" list. (wikipedia.org)
  • Microbiology
  • E. coli is the most widely studied prokaryotic model organism, and an important species in the fields of biotechnology and microbiology, where it has served as the host organism for the majority of work with recombinant DNA. (wikipedia.org)
  • Because of its long history of laboratory culture and ease of manipulation, E. coli also plays an important role in modern biological engineering and industrial microbiology. (wikipedia.org)
  • outbreak
  • A U.S. outbreak of E. coli O121 in 2013 sickened 24 people in 15 states according to a statement released by the CDC. (wikipedia.org)
  • In 2016, General Mills recalled 10 million pounds of wheat flour tied to an E. coli O121 outbreak. (wikipedia.org)
  • E. coli O104:H21 was discovered in 1982, when it caused an outbreak of severe bloody diarrhea. (wikipedia.org)
  • coliform
  • Typical genera include: Citrobacter Enterobacter Hafnia Klebsiella Escherichia Escherichia coli (E. coli), a rod-shaped member of the coliforms group, can be distinguished from most other coliforms by its ability to ferment lactose at 44°C in the fecal coliform test, and by its growth and color reaction on certain types of culture media. (wikipedia.org)
  • Escherichia coli have an incubation period of 12-72 hours with the optimal growth temperature being 30-37°C. Unlike the general coliform group, E. coli are almost exclusively of fecal origin and their presence is thus an effective confirmation of fecal contamination. (wikipedia.org)
  • Mixed Acid Ferment
  • E. coli can live on a wide variety of substrates and uses mixed-acid fermentation in anaerobic conditions, producing lactate, succinate, ethanol, acetate, and carbon dioxide. (wikipedia.org)
  • Gram Negative
  • E. coli is a Gram-negative, facultative anaerobic (that makes ATP by aerobic respiration if oxygen is present, but is capable of switching to fermentation or anaerobic respiration if oxygen is absent) and nonsporulating bacterium. (wikipedia.org)
  • E. coli stains Gram-negative because its cell wall is composed of a thin peptidoglycan layer and an outer membrane. (wikipedia.org)
  • anaerobic
  • E. Coli is capable of switching from aerobic to anaerobic respiration, although anaerobic respiration is preferred. (prezi.com)
  • plasmids
  • The work of Stanley Norman Cohen and Herbert Boyer in E. coli, using plasmids and restriction enzymes to create recombinant DNA, became a foundation of biotechnology. (wikipedia.org)
