Species code:	ECODH
Taxonomy:	Bacteria; Proteobacteria; Gammaproteobacteria; Enterobacteriales; Enterobacteriaceae; Escherichia (TaxID: 316385) [NEWT/ NCBI]
Description:	Escherichia coli is a Gram-negative straight rod, which either uses peritrichous flagella for mobility or is nonmotile. It is a facultatively anaerobic chemoorganotroph capable of both respiratory and fermentative metabolism. E.coli serves a useful function in the body by suppressing the growth of harmful bacterial species and by synthesizing appreciable amounts of vitamins. It is an important component of the biosphere. It colonizes the lower gut of animals and survives when released to the natural environment, allowing widespread dissemination to new hosts. Pathogenic E.coli strains are responsible for infection of the enteric, urinary, pulmonary and nervous systems. Strain DH10B is a derivative of the already sequenced K12; it is extensively used in molecular biology as it is easily transformed and allows maintenance of large plasmids (especially useful for genomic sequencing projects). The genome sequence has revealed that there are 226 mutations compared to K12/MG1655 and that it has dramatically more insertion sequence transposition than does MG1655, which results in a 13.5-fold higher mutation rate than MG1655. It is a leucine auxotroph. The sequence was assembled from "contaminating" sequence gathered during the bovine genome sequencing project.
