EcoCyc contains written summaries of E. coli genes, distilled from over 36,000 scientific articles. EcoCyc is also a description of the genome and cellular networks of E. coli that supports scientists to carry out computational analyses. [2] Data objects in the EcoCyc database describe each E. coli gene and gene product.
E. coli is the type species of the genus (Escherichia) and in turn Escherichia is the type genus of the family Enterobacteriaceae, where the family name does not stem from the genus Enterobacter + "i" (sic.) + "aceae", but from "enterobacterium" + "aceae" (enterobacterium being not a genus, but an alternative trivial name to enteric bacterium).
Adherence to host uroepithelial cells is a crucial step during the infection that allows uropathogenic E.coli to colonize the urinary tract and prevents bacterial removal during micturition. The binding of the P fimbriae to epithelial cells is mediated by the tip adhesin PapG.
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 ...
A review of 22 studies in 1998 [10] confirmed that the health risks for swimmers increased as the number of indicator bacteria increased in recreational waters and that E. coli and enterococci concentrations correlated best with health outcomes among all the indicators studied. The relative risk (RR) of illness for swimmers in polluted ...
ESKAPE is an acronym comprising the scientific names of six highly virulent and antibiotic resistant bacterial pathogens including: Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter spp. [1] The acronym is sometimes extended to ESKAPEE to include Escherichia coli. [2]
The LacUV5 promoter is derived from the E. coli wildtype lac promoter but exhibits an increased transcription strength due to two mutations that facilitate its interaction with a native E. coli RNAP σ-factor. [7] In E. coli BL21(DE3) the expression of the T7-RNAP is suppressed by the constitutively expressed LacI repressor.
Super Optimal Broth (SOB medium) is a nutrient-rich bacterial growth medium used for microbiological culture, generally of Escherichia coli.This nutrient-rich microbial broth contains peptides, amino acids, water soluble vitamins and glucose in a low-salt formulation.
