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 coli (AIEC), morbus Crohn ...
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]
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.
Escherichia coli BL21(DE3) is a commonly used protein production strain of the E. coli bacterium. 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 ...
Escherichia coli (E. coli), common Gram-negative gut bacterium widely used in molecular genetics. Main lab strain is 'K-12'. Bacillus subtilis, endospore forming Gram-positive bacterium. Main lab strain is '168'. Caulobacter crescentus, bacterium that divides into two distinct cells used to study cellular differentiation.
BacDive was initially released in April 2012 to standardize and make publicly available strain data of culture collections, other compendia, and publications. The first release, contained 89,758 entries for 18,157 strains and 179 different used data fields. [6] Today (as of December 2023), the database encompassed over 1000 different data fields.
Escherichia coli have an incubation period of 12–72 hours with the optimal growth temperature being 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. Most strains of E. coli are harmless, but some can cause serious illness in ...
