SUMMARY The shape of Escherichia coli is strikingly simple compared to those of higher eukaryotes In fact, the end result of E coli morphogenesis is a cylindrical tube with hemispherical caps It is argued that physical principles affect biological forms In this view, genes code for products that contribute to the production of suitable structures for physical factors to act uponE coli , a bacillus of about average size is 11 to 15 µm wide by to 60 µm long Spirochaetes occasionally reach 500 µm in length and the cyanobacterium;Oscillatoria 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)

E coli is a type of bacteria that normally live in the intestines of people and animals However, some types of E coli , particularly E coli O157H7, can cause intestinal infectionE coli Shape (form) circular Margin entire Elevation raised Size punctiform, small Texture (surface) smooth Appearance shiny Pigmentation nonpigmented (colorless) Optical property translucent S aureus Shape (form) circular Margin entire Elevation convex Size moderate, large Texture (surface) rough Appearance shiny Pigmentation tan, golden yellow Optical property opaque ForEscherichia 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 food

Symptoms of Shiga toxinproducing E coli (STEC) infection vary for each person, but often include severe stomach cramps, diarrhea (often bloody), and vomitingSome people may have a fever, which usually is not very high (less than 101˚F/385˚C) Most people get better within 5 to 7 daysOscillatoria 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)List at least 3 differences between gram positive and gram negative bacteria

What are the gram reaction, shape, and arrangement of E coli?The primary habitat of E coli is in the gastrointestinal (GI) tract of humans and many other warmblooded animalsWhen 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
