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. Comparison of 20 E.coli/Shigella strains shows the core genome to be about 2000 genes while the pan-genome has over 18,000 genes. There are multiple, striking integration hotspots that are conserved across the genomes, corresponding to regions of abundant and parallel insertions and deletions of genetic material.

Strain SE11, a commensal bacterium, was isolated from the feces of a healthy human adult. It belongs to the E.coli phylogenetic group B1. It possesses more genes involved in the metabolism of carbohydrates as well as genes for adhesion than the laboratory workhorse strain MG1655 (which is no longer able to colonize the human gut). These genes are associated with uptake of available nutrients, allowing E. coli to survive in the intestinal tract rich in oligo- and polysaccharides (adapted from PubMed 18931093).
