Enteroaggregative E. coli (EAEC) Uropathogenic E. coli (UPEC) Verotoxin-producing E. coli; E. coli O157:H7 is an enterohemorrhagic strain also 2006 North American E. coli outbreak; E. coli O104:H4, also 2011 E. coli O104:H4 outbreak; Escherichia coli O121; Escherichia coli O104:H21; Escherichia coli K1, meningitis; Adherent Invasive Escherichia ...
Escherichia coli (/ ˌ ɛ ʃ ɪ ˈ r ɪ k i ə ˈ k oʊ l aɪ /; commonly abbreviated E. coli) is a Gram-negative gammaproteobacterium commonly found in the lower intestine of warm-blooded organisms (endotherms). The descendants of two isolates, K-12 and B strain, are used routinely in molecular biology as both a tool and a model organism.
All commonly used research strains of E. coli belong to group A and are derived mainly from Clifton's K-12 strain (λ + F +; O16) and to a lesser degree from d'Herelle's "Bacillus coli" strain (B strain; O7). There have been multiple proposals to revise the taxonomy to match phylogeny. [52]
According to the FDA, E. coli is often innocuous. You might even have some living in your gut. But there are different strains of E. coli, and some can be potentially dangerous. This recall ...
Escherichia coli BL21(DE3) is a commonly used protein production strain. This strain combines several features that allow for excessive expression of heterologous proteins . It is derived from the B lineage of E. coli .
E. coli (EIEC) found only in humans Bloody or nonbloody EIEC infection causes a syndrome that is identical to shigellosis, with profuse diarrhea and high fever. Enterohemorrhagic E. coli (EHEC) found in humans, cattle, and goats Bloody or nonbloody The most infamous member of this pathotype is strain O157:H7, which causes bloody diarrhea and no ...
The strain of E. coli Lenski chose to use in the long-term evolution experiment was derived from "strain B", as described in a 1966 paper by Seymour Lederberg (which incorrectly identified the strain as "Bc251", although later genetic analysis found it to be "B" instead), via Bruce Levin, who had used it in a bacterial ecology experiment in 1972.
Shigatoxigenic Escherichia coli (STEC) and verotoxigenic E. coli (VTEC) are strains of the bacterium Escherichia coli that produce Shiga toxin (or verotoxin). [ a ] Only a minority of the strains cause illness in humans.
