Extract of sample "Escherichia Coli"

Download file to see previous pages The mobility is provided to it by flagellum, which is referred to as peritrichous flagella that are present on all sides of the bacteria. The bacterium does not have the property of forming spores. The bacterium has three antigens present. The antigen which is present on the cell wall of the bacteria is the “O” antigen, the antigen which is present on the flagellum is the “H” antigen and the antigen which is found on the capsule of the bacteria is the “K” antigen. These antigens have great variability with each of them existing in many different forms. This is the reason that E. coli exists in many different forms.
This bacteria has been associated with many pathological conditions which include the inflammation of the gallbladder, inflammation of the biliary tract, infections of the urinary tract and the blood as well as diarrhea particularly traveler’s diarrhea. The newborns are also affected by it and present with inflammation of the meninges. Though this inflammation has also been reported in adults it is more common in newborn children and it usually occurs in adults as a result of invasive procedures. The respiratory tract might also be involved with resultant pneumonia.
This bacterium is responsible for infections of the urinary tract in 50 percent of women in the United States. This is because there is a greater disposition towards females of this infection owing to the increased hospital visits related to deliveries and their higher susceptibility during the childbearing period. But this pattern is different for the newborns in which the rate of the infection of the urinary tract is higher in male children than in females.
E. coli is also listed as an infection which occurs in the hospital settings and has been associated with an average of 31 percent hospital-acquired infections in the United States as well as a cause of diarrhea in 4 percent of the people.  ...Download file to see next pagesRead More

Escherichia Coli bacterium

...?Ar Escherichia Coli ESCHERICHIA COLI Introduction: Escherichia coli is a bacterium which is referred to as an enterobacteriacea that is a bacteria that exists normally in the intestine of human and animals. This bacterium which exists in the form of gram negative rods has been named after the man, Theodor Escherich who discovered them in the year 1885. This bacterium is not completely aerobic that is it can survive in the presence of oxygen and it also has the capability to exist in the absence of oxygen by the process of fermentation. E. coli also has the property of movement though there are certain forms of the bacteria that form exceptions and do not move. The mobility is provided to it by flagellum, which is referred... 0157:H7....

ESBL positive Escherichia coli and Klebsiella interaction with human urothelial cells

..., Providencia, Salmonella, Serratia, Shigella and Yersinia (Health Protection Agency, 2010). 1.3. Escherichia coli The most important infective organism in UTI is Escherichia coli, but other Enterobacteriaceae species like Klebsiella, Citrobacter and Enterobacter also cause UTI. Proteus mirabilis, and Providencia stuartii and Morganella morganii, which are urease producers, are also common. Other species identified in patients with UTI are Pseudomonas aeruginosa, enterococci, group B streptococci and coagulase-negative staphylococci. Yeast strains Candida albicans, C. tropicalis, C. glabrata, and C. parapsilosis have also been isolated mostly from patients with indwelling...

Molecular Mechanism of antibiotic resistance in Escherichia coli

...? Molecular Mechanism of antibiotic resistance in Escherichia coli Unit: Background: Resistance to antibiotics in E.coli and other bacteria is conferred to them by gene transfers and mutations. The main aims and outcomes of such are strains that are more virulent and tolerant to harsh conditions crated by antibiotic therapy. Results: Research into the molecular mechanisms highlights several mechanisms such as target modification, enzymatic breakdown and rapid efflux. The genes are obtained by horizontal transfer. They may be expressed together or as a single, with the effect of reducing the effect of the antibiotic on the cell. Conclusion: Sufficient research results have shown that the E.coli continues...

Escherichia coli

...E-Coli Introduction Escherichia coli (E. coli), is among the important species of bacteria that dwells in the lower intestines of mammals. It is also known as gut flora which is useful when located in the large instestine and assists with waste processing, vitamin K production, and food absorption. Earlier Escherichia coli was originally known as Bacterium coli commune that was discovered in 1885 by the German pediatrician and bacteriologist, Theodor Escherich. E. coli belongs to the family Enterobacteriaceae (American Public Health Association 1998). It is abundant in human body and the number of individual E. coli bacteria found in the human feces every day averages between 100 billion and 10 trillion. E-coli is also found... and...

Quorum sensing in Escherichia coli and Salmonella typhimurium

...1. What is the possible role of quorum sensing in Escherichia coli and Salmonella typhimurium? The possible role of E.coli and S. typhimurium in quorum sensing is shown to be the production of a signaling substance that stimulates one particular quorum-sensing system which is a species non-specific system in Vibrio harveyi. The signal produced by E.coli and S. typhimurium was seen to be potent and equal to that of V. harveyi. The results also showed that the quorum sensing in these two bacteria differs from other quorum sensing bacteria in a way that it is tuned for a lower cell-density community as the signal is degraded before it enters the stationary phase. The influence of environmental factors on quorum sensing as seen... of...

An Escherichia coli O157:H7 Outbreak among Teenage Campers

...An Escherichia coli O157:H7 Outbreak among Teenage Campers Question The procedure involved in identifying the pathogen includes the history of individual campers. This happens through interviewing the campers and finding out the possibility of either of them suffering from the disease before arriving at the camp. The next way of identifying the pathogen is by checking and testing the feed in the camp and establishing their status of infection. Checking the hygienic condition of the environment to establish any source of infection is also another possible way of tracking the root of infection. Question 2 Most of the E. coli strains are beneficial in the gut because it is gram-negative...
