    Escherichia coli (Latin pronunciation: [eskeˈrikja ˈkoli] Anglicized to / ˌ ɛ ʃ ə ˈ r ɪ k i ə ˈ k oʊ l aɪ /; commonly abbreviated E. coli) is a gram-negative, rod-shaped bacterium that is commonly found in the lower intestine of warm-blooded organisms (endotherms).

    en.wikipedia.org › wiki › Entamoeba_coli

    Entamoeba coli is a non-pathogenic species of Entamoeba that frequently exists as a commensal parasite in the human gastrointestinal tract. E. coli (not to be confused with the bacterium Escherichia coli) is important in medicine because it can be confused during microscopic examination of stained stool specimens with the pathogenic Entamoeba histolytica.

    Strong lactose fermenters will appear as dark blue/purple/black, and E.coli (which also ferments lactose) colonies will be dark colored, but will also appear to have a metallic green sheen. Other coliform bacteria will appear as thick, slimy colonies, with non-fermenters being colorless, and weak fermenters being pink.

    Cell shape and E. coli. Depending on the growth conditions, E. coli varies in size; fast-growing cells are bigger than slowly growing ones (for a review, see reference123). At all growth rates, its shape can be roughly approximated by a cylinder with hemispherical ends.

    Phage P1 exhibits the classical bacteriophage morphology with an icosahedral head, 220nm long inflexible tail with a complete tube surrounded by a contractile sheath, baseplate and six kinked tail fibers. The icosahedral head contains the phage genome. A variable part(encoded by an invertible segment of P1 DNA) of the tail fibers(1 to 2nm thick) determines the specificity of P1 adsorption on different hosts.

Protein-coding genes occupy 92% of the genome. 4 of the 45 operons are responsible for the choice between lysis and lysogeny and another 4 are responsible for plasmid maintenance. The remaining 37 are invovled in lytic development. Regulatory regions of 38 operons contain one or more sequences that resemble strong δ70promoters. In the virion, DNA is double stranded, linear, terminally redundant and circularly permuted. The terminal redundant region is important because foreign pieces of DNA can be inserted in non-essential regions.
