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

Instead, their genetic material floats uncovered4 Applying counterstain (safrinin) to bacterial smear as last step of endospore stain;When viewed under the microscope, Gramnegative E Coli will appear pink in color The absence of this (of purple color) is indicative of Grampositive bacteria and the absence of Gramnegative E Coli Escherichia coli under 10х90х magnification using fuchsine as a dye by ElNokko (Own work) CC BYSA 40 (http//creativecommonsorg/licenses/bysa/40), via Wikimedia Commons

Biology Of E Coli E coli (Escherichia coli) are a small, Gramnegative species of bacteriaMost strains of E coli are rodshaped and measure about μm long and 0210 μm in diameterThey typically have a cell volume of 0607 μm, most of which is filled by the cytoplasm Since it is a prokaryote, E coli don't have nuclei;Bacteria species E coli and S aureus under the microscope with different magnifications Bacteria are among the smallest, simplest and most ancient livingOscillatoria is about 7 µm in diameter The bacterium, Epulosiscium fishelsoni , can be seen with the naked eye (600 µm long by 80 µm in diameter)

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
