Virulent E. coli Microbiology, Virulent E. coli Eschierichia coli is a gram-negative bacterium that resides in the intestines of tender-hearted races and animals. Its presence is known for many years as a harmless commensal and is considered part of the normal botany of the large intestine. By normal, it does no harm in the human intestines instead along with other bacterium, they live together in the commune helping to inhibit or ward bungle other deadly or pathogenic bacteria. On occasion, these bacteria such as E. coli breach or acquire true characteristics that render them harmful and especially if they invade another luggage compartment site. It is those times that the bacteria become virulent. By this they have toxins (poisons) or other mechanisms that create disease states in the body. Let us address these developments. Due to the close proximity of the anus and the vagina, E. coli which is found unremarkably in the large intestine is one of the leading causes of urinary tract infection (UTI) along with prostatitis and pyelonephritis. Many of these infections are hospital acquired referring to them as nosocomial. The transmission of these nosocomial infections arise from the medical or hospital staff. These people are colonized with the bacteria in their rectum, vagina or on the turn over. (Baron, 1996, p. 355).
Failure to properly race hands or wear gloves when attending to patient greatly extend the transmission of the bacteria especially E.coli. This is the greatest nocosomial pathogen. withal near 80% of the community-acquired UTI is attri only whenable to E. coli. Therefore! , since the pH, environment and other factors ingrain the bacteria, they develop mechanisms for their survival. These include hemolysins, capsules, antigens and what is known as adherence pili or attachments. (Baron, 1996, p.347). In the laboratory, E. coli is recognized as a lactose fermenter on the MacConkey civilization media shield. The colonies are flat and dry on the media plate but occasionally...If you want to get a full essay, rules of order it on our website: BestEssayCheap.com
