Escherichia coli

E. coli is basically responsible for many intestinal and extra-intestinal infections. Some of these infewctions incluse meningitis, peritonitis, urinary tract infections, septicemia, Gram-negative pneumonia and mastitis. Based on the virulence properties of the enteric E. coli, these are subdivided into the following: enterotoxigenic, enterotoxigenic, enteroinvasive, verotoxigenic, enterohaemorrhagic and enteroaggregative E. coli. Enterotoxigenic (ETEC), is the causative agent of diarrhea in humans, pigs, sheep, goats, cattle, dogs, and horses. Enteropathogenic (EPEC) is the causative agent of diarrhea in humans, rabbits, dogs, cats and horses. Enteroinvasive (EIEC), is found only in humans, where as verotoxigenic (VTEC) is found in pigs, cattle, dogs and cats. Enterohaemorrhagic (EHEC) is found in humans, cattle, and goats, attacking porcine strains that colonize the gut in the same way as human EPEC strains and enteroaggregative E. coli..
Food industry plays a major role in the spread of diseases by e-coli. Most illness has been linked with consumption of undercooked, contaminated ground beef. There are also vegetarian sources as people have also become ill from eating contaminated bean sprouts or fresh leafy vegetables such as lettuce and spinach. Escherichia coli O157:H7 is a leading cause of food-borne illness in various parts of the world. E. coli O157:H7 was first recognized as a cause of illness in 1982 during an outbreak of severe bloody diarrhea; the outbreak was traced to contaminated hamburgers. ...

Experiment on the bacterium Escherichia coli
Escherichia coli (E.coli) are gram negative, non-spore forming strains of bacterium that usually inhabit the intestinal tracts of humans and other warm-blooded animals. They are facultative anaerobes that ferment simple sugars like glucose into lactic, acetic and formic acids (HITM, 2006). Most E coli strains are harmless and even are beneficial in the sense that they assist the host by destroying other harmful strains of bacterium and by synthesising sizeable amounts of vitamins (HITM, 2006). Nevertheless, there are certain strains of E coli that prove harmful to humans and other hosts. These...

Rapid Colony Transformation of E -Coli with Plasmid DNA
The paper "Rapid Colony Transformation of E -Coli with Plasmid DNA" analyzes E-Coli transformed by plasmid DNA using a rapid method. The transformation method can be categorized into four stages. The first is Pre-incubation stage. The low temperature gels the cell membrane, thereby stabilizing the distribution of charged phosphates and allowing them a more effective shield from the cat ions. The second stage is Incubation. The DNA is added and the cell suspension is kept at 0ºC.the cat ions are thought to neutralize negatively charged phosphates in the DNA and the cell membrane. The third...

Epidemiologic Investigation
In the context of this project, the disease agent is a particular strain of E. coli that is well regarded as a food borne pathogen responsible for an infectious diarrheal disease. By definition, the characterization of the disease is intimately related to characterization of the agent that initiates or perpetuates the disease process.

The mobility is provided to it by flagellum, which is referred to as peritrichous flagella that is 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....

Strains of E. coli are capable of producing vitamin K2 and K3. Gram-negative cells are protective in nature and prevent entry toxins. This factor helps in preventing entry of other microorganisms. The protective nature of gram-negative bacteria also makes them resistant to infections due to the nature of their cell membrane. Nonpathogenic strains of E. coli can also be easily studied due to their ability to survive outside the body. The bacteria also grow easily which provide a good platform for studies.
