Identify E-Coli Bacteria in Fresh Vegetables

What is E. coli? Escherichia coli (E. coli) be gram-negative bacterium that trick survive in an environment with or without air (facultative anaerobes) and, depending on the environment, may or may not produce thin hair-like structures (flagella or pili) that lose the bacteria to move and to attach to human cells. These bacteria normally live in the bowels of people and animals worldwide. There atomic number 18 legion(predicate) strains (over 700 serotypes) of E. coli. close to of the E. coli are normal inhabitants of the infinitesimal intestine and colon and do not spend a penny disease in the intestines (non-pathogenic). Nevertheless, these non-pathogenic E. coli can set about disease if they spread outside of the intestines, for example, into the urinary parcel (where they cause bladder or kidney infections), or into the blood catamenia (sepsis). separate E. coli strains (enterovirulent E. coli strains or EEC) cause poisoning or looseness stock-still though the y usually remain within the intestine by producing toxins or intestinal inflammation. There are quadruplet to sextet groups (some researchers combine groups) of E. coli strains that comprise EEC. EHEC (enterohemorrhagic E. coli) ETEC (enterotoxigenic E. coli) EPEC (enteropathogenic E. coli) EIEC (enteroinvasive E. coli EAEC (enteroadherent E. coli EAggEC (enteroaggregative E. coli) E. coli were first isolated by T. Escherich in 1885 and were named after him. The over 700 serotypes are set by small antigenic changes in their surface O antigens (lipopolysaccharides or molecules on the bacterial surface of gram-negative bacteria), for example E. coli 0157 or E. coli 055. These serotypes are identified by immunological tests. E coli strains are besides distinguished by H protein antigens (different types of flagella that make the bacteria motile). Consequently, a particular E. coli strain can be identified as H, followed by a number, and this identifier is added t! o the O name; for example, E. coli 0157:H7....If you motivation to cleave a full essay, order it on our website: OrderEssay.net
