The bacteria called E.coli affects the digestive system when entered the body. The three main
E.coli is a member of the Enterobacteriaceae family which is also where Salmonella typhinurium is also classified. E.coli lives in the intestines of humans and can cause many infections ranging in severity. It doesn 't even require any growth factors, and can synthesize all essential purines, pyrimidines, amino acids and vitamins, starting with their carbon source, as part of their own intermediary metabolism (Todar). I was nervous about working with E.coli and bacteria because in general before starting this lab because of some of the symptoms they can cause. Especially intestinal swelling (MedLineplus). Even with that stated I have grown to enjoy this experiment and have learned so much valuable information that will benefit me in my nursing…
Escherichia coli are gram- negative bacteria that are normally found within the gut of warm bloodied organisms. There are several strains of E. coli that exist as part of the normal flora of the human digestive system. They prevent harmful bacteria from establishing themselves in the intestines, and they also aide in the production of vitamin K2. Most E. coli strains are not harmful to humans, except for serotype O157:H7, which causes food poisiong and can be life threatening. There are other less common serotypes of E. coli. We will be discussing Escherichia coli O26, which has been linked to an outbreak involving raw clover sprouts.…

coli is a gram negative, bacterium found in the lower intestine of warm blooded organisms. Although E.coli strains are harmless there are serotypes that can cause food poisoning in humans. [2] Harmless strains can be found in the flora of the gut and produce vitamin k¬¬2 and prevent pathogenic bacteria from establishing and are therefore beneficial to the host. The major cause for disease is fecal to oral transmission. It is an ideal candidate for bacterial transformation because it is made of only one cell, reproduces every 20 minutes, is not harmful to people, and cannot survive outside the…
E.coli was found facultative anaerobe because the growth was seen throughout the middle but was not near the…
Most types of Escherichia coli are harmless and are actually a part of a healthy human intestinal tract but some are pathogenic. It can be transmitted multiple ways; fecal-oral route, fecal contamination of water, food or fomites, poor sanitation and hygiene (General Microbiology Fact Sheet). A person can show signs and symptoms of Escherichia coli which include fever, bloody diarrhea, may result in hypotension with severe toxemia. The incubation period is 12-72 hours. Knowing the steps and process of finding an unknown is helpful when it comes to the different types of bacteria’s and which are harmful to the body and how to treat…
Bacteria. These organisms are made up of just one cell. They have the power to divide so can multiply on their own. Some bacteria are harmless and can be of use in the aid of digestion and are found in the intestines. Other bacteria can be the cause of diseases. These bacteria have to find a way in to the body to be of harm and can make their way through the skin or be digested and attack our immune system.…
A subset of this group of bacteria is known collectively as fecal coliforms, which includes the well-known E. coli, some strains of which are necessary for human health, and some which are pathogenic and can make you very sick. Although the beneficial strains of this bacteria aid human digestion, finding these bacteria in waterways serves as a warning for the potential spread of disease because they can indicate human or animal feces. Therefore, coliform bacteria are used in water quality testing as indicators of other pathogenic bacteria that commonly are found associated with coliforms, e.g., Salmonella, Shigella, Yersinia, Klebsiella and certain strains of E. coli.…
A bacteria or virus can initially prompt an immune response as the body attacks the invading microorganism in the gut. However, this immune response may also trigger the body to abnormally attack its own digestive tract…

On November 14, 2012, Rita Bernstein visited Bergen Community College to talk about Escherichia Coli O157:H7. Escherichia coli or better known as E.coli is a tube-shaped bacterium that is found in the stomachs of warm-blooded animals. O157:H7 is a member of the E.coli family, which produces shiga toxin, and are capable of producing bloody diarrhea. E.coli O157:H7 attacks red blood cells, it interrupts flow of oxygen, and it breaks down walls of vessels.…
The Escherichia Coli 0157:H7 or also know as E Coli, is a food born pathogen that can cause serious illness to humans at any age. The E Coli can also lead to death if left untreated. There are many symptoms with the E Coli. And one of the most obvious symptoms is having a bloody diarrhea (Not all forms of E Coli have the same symptoms).…
The principal structure of the digestive system is an irregular tube, open at both ends, called the alimentary (al-i-MEN-tar-ee) canal or the gastrointestinal (GI) tract.…
A number of other problems may be associated with colitis. These are more likely when the disease is active and include skin…
In 2013, a study on bacterial E. Coli was performed, by Jabus G. Tyerman, to observe how the bacteria reacted with different types of antibiotics. This study was performed over a 60-day period in order for the researchers to obtain some significant data. The…
