Escherichia coli bacterium, 2021, Illustration by David S. Goodsell, RCSB Protein Data Bank This painting shows a cross-section through an Escherichia coli cell. The characteristic two-membrane cell wall of gram-negative bacteria is shown in green, with many lipopolysaccharide chains extending from the surface and a network of cross-linked ...
Enterobacteriaceae is a large family of Gram-negative bacteria.It includes over 30 genera and more than 100 species. Its classification above the level of family is still a subject of debate, but one classification places it in the order Enterobacterales of the class Gammaproteobacteria in the phylum Pseudomonadota.
After gaining entry to the bladder, E. Coli are able to attach to the bladder wall and form a biofilm that resists the body's immune response. [7] Escherichia coli is the single most common microorganism, followed by Klebsiella and Proteus spp., to cause urinary tract infection. Klebsiella and Proteus spp., are frequently associated with stone ...
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.
An outbreak of the Escherichia coli O157 bacterium occurred in South Wales in 2005. It was the largest outbreak of E. coli O157 in Wales and the second largest in the UK. [1] 157 cases were identified in the outbreak; 31 people were hospitalized, and there was a single fatality. Most of the 157 cases identified were children, attending 44 ...
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, the bacterium in which MCR-1 was first identified. The mobilized colistin resistance (mcr) gene confers plasmid-mediated resistance to colistin, one of a number of last-resort antibiotics for treating Gram-negative infections. mcr-1, the original variant, is capable of horizontal transfer between different strains of a bacterial species.
Colibactin is a genotoxic metabolite produced by Escherichia coli and other Enterobacteriaceae ("enteric bacteria") believed to cause mutations leading to colorectal cancer and the progression of colorectal cancer.
