Escherichia coli (/ ˌ ɛ ʃ ə ˈ r ɪ k i ə ˈ k oʊ l aɪ /), also known as E coli (/ ˌ iː ˈ k oʊ l aɪ /), is a Gramnegative, facultative anaerobic, rodshaped, coliform bacterium of the genus Escherichia that is commonly found in the lower intestine of warmblooded organisms (endotherms) Most E coli strains are harmless, but some serotypes (EPEC, ETEC etc) can cause serious foodMixed Culture (Gram Stain) E coli and S epidermidis (1000X) Klebsiella pneumoniae (1000X) Capsule Stain Capsule Stain (1000X) Commercially Prepared Slide In some bacteria, the cell wall is surrounded by a viscous cell envelope called 'capsule' It is made of polysaccharide, glycoprotein or polypeptideThe length can range from 110 µm for filamentous or rodshaped bacteria The most wellknown bacteria E coli, their average size is ~15 µm in diameter and 26 µm in length In this figure The size comparison between our hair (~ 60 µm) and E coli (~1 µm) Notice how small the bacteria are It requires 1000x magnification to see them

Phase contrast microscopy was used to observe the live E coli and B megaterium cells on wet mount slides under 1000x magnification The E coli cell sizes ranged from 1 µm 6 µm, but most of them averaged around 2 µm 3 µm The E coli cells were bacilli shaped and uniform throughout the sample The E coli cellsEscherichia coli, often abbreviated E coli, are rodshaped bacteria that tend to occur individually and in large clumps E coli are classified as facultative anaerobes, which means that they grow best when oxygen is present but are able to switch to nonoxygendependent chemical processes in the absence of oxygenPlace the slide on a staining rack and add a few drops of crystal violet onto the sample, gently wash with water Add a few drops of Gram iodine (mordant) for between 30 seconds and 1 minute, gently wash with water Add a few drops of alcohol (95% alcohol) for about 10 seconds, gently wash with water
