E. Coli Pathogenic Bacteria

2. Why do you think Mrs. Garner's students did not become ill, while Ms. Hines' kids did?

In ground beef you can get E. coli because they slaughter the cow and then the E. coli from there intestine gets on the ground meat and they mix the meat and then that gives it a higher risk of spreading it.(Staff Mayo Clinic) In unpasteurized milk it comes from the udder of the cow and then it gets into the milk. (Staff Mayo Clinic) In fresh food it comes from the farms that can contaminate the farm. The most vulnerable to this is lettuce and spinach. (Staff Mayo Clinic) In contaminated water there can be E. coli because it untreated and there is feces in it.(Staff Mayo Clinic) Also personal contact which means that adults can give it to their kids because they do not wash their hands after using the bathroom.(Staff Mayo Clinic) Also it passed in restaurants because cooks or people working back their do not wash their hands. E. coli causes the hemolytic-urine syndrome, which is a blood and kidney disease in children. It can also cause Uninary tract infections and bladder infections or it can lead to sepsis. There is another cause Thrombotic thrombocytopenic Purpura. This is a rare blood disease. It causes clots to form in small blood vessels throughout the body. This usually causes through the infectious parts of E. coli.

E. coli bacteria affects children and the elderly along with people with weak immune systems.

E.coli outbreaks have steadily grown over the last few decades. An expansion in big farming has led to E. coli not only being found in meat, but vegetation as well, due to waste runoff. This has increased our need for adequate antibiotics that can fight bacteria, like E. coli. The best way to pinpoint which antibiotics work is by measuring their ability to create antimicrobial agents or zones of inhibition. When a paper disc that has been saturated in an antibiotic is inserted in a solution of E.coli and medium, the zone of inhibition will be noted as the clear ring that forms around the disk. The antibiotics efficacy is then determined by measuring each disk zone of inhibition, and comparing these measurements to the zone measurements of an untreated specimen. If an antibiotic is to be deemed sufficient for treating E. coli it should show a zone of inhibition that is at least double the size of the untreated specimen.

Escherichia coli are gram negative, rod shaped bacteria that are often used in laboratory studies and are usually harmless, residing in the human digestive tract as part of the normal flora. E. coli 0157:H7 is a pathogenic strain of E. coli that was first identified as a cause of disease in the United States in 1982, during an investigation into an outbreak of gastrointestinal illness. The organism is also called enterohemorrhagic E. coli (EHEC) because it causes abdominal pain with diarrhea that may contain blood. It lives in the intestines of healthy cattle and can contaminate meat during slaughter. It is believed that the widespread use of antibiotics by American farmers has

E. coli or Escherichia coli are a kind of bacteria that affects the intestinal or the digestive system of a human being, which can even lead to death. It is one of the subgroup of fecal coliform bacteria. E. coli O157:H7 is that toxic microorganism or bacteria which causes the intestinal disease in the human beings which is most likely to last about a week. The common symptoms of these diseases are that the patient will have diarrhea with blood (Clermont, Bonacorsi and Bingen 2000). However, the serve cases of this disease may lead to kidney problems, which can lead to death especially when the patient is a child or an elderly person. That is, it can act severely in those patients who have does not have a strong immune system. Some types of E. coli are normally found in the intestines of people and animals

E. coli or Escherichia coli is a prokaryotic cell found the in lower digestive track of mammals and other warm blooded animals. E. coli is an easy bacteria to work with as it doubles quickly and is relatively easy to grow, millions of cells can be grown in several hours. E. coli is an ideal bacteria in the lab because it does not require its temperature to be too hot, too cold, or too precise. A general warm temperature is perfect for this bacteria. E. coli is also easy to care for it does not need a specific type of nutrient, in a lab setting it can be feed any agar, making the bacteria over all cheaper to care for. Strains of E. coli can also operate in aerobic or anaerobic environments.

E. coli bacteria normally lies in the intestinal tract of people and animals. In most cases, E. coli is a harmless bacterium and even serves as an essential part of a healthy human intestinal tract. However, there are multiple types of E. coli and some are pathogenic, meaning they can cause illness. Pathogenic E. coli strains are categorized into six pathotypes: STEC, EHEC, ETEC, EPEC, EAEC, EIEC, and DAEC. Pathogenic forms of E. coli bacteria are able to infiltrate, grow and live in a variety of foods and beverages. Once a food or beverage is contaminated and then consumed, the individual who has consumed it is at risk of an E. coli infection.

coli bacteria is a type of bacteria that can live in the intestines of animals and humans. However, there are some types of the E. coli bacteria, particularly E. coli 0157:H7, that can cause intestinal infections. Symptoms of this type of infection include dehydration, abdominal cramps, fever and bloody diarrhoea. These symptoms can endure 2-8 days after exposure to the bacteria. Since these symptoms generally resolve after a few days to a week, most cases of E. coli 0157:H7 infection can be treated at home.

E. coli are usually harmless, but can cause urinary tract infections, respiratory illnesses and other illnesses. This bacterium is also beneficial to humans and are part of our natural intestinal microflora, but E. coli can also lead to mild to serious illnesses in the human body. Disease causing E. coli are grouped according to the ways they cause illnesses. Escherichia coli is spread when people consume at-risk foods, these include foods such as undercooked ground beef, produce that have come into contact with fecal matter, contaminated water and unpasteurized dairy and juice products. This bacterium can also spread from person to person by unwashed hands, contaminated surfaces (fomites) and pond water.

Escherichia coli, oe e.coli, is a safe bacteria found in the large intestine, but also a dangerous bacteria outside of the body. While inside the body the bacteria produces vitamin K which cannot be obtained from food. Therefore e.coli is an essential bacteria in the human body. This bacteria is also a facultative anaerobe meaning it can live with and without oxygen. This means that it can thrive inside of the body, but it can also thrive outside of the body. When e.coli is outside of the body it is very dangerous. E.coli can be found in uncooked meats, unpeeled vegetables, unwashed fruits, and everything contaminated with feces. Dr. Harrlet Burge (2011) stated that e.coli can survive in water for up to 100 days and can remain in soil for as many as 15 weeks. Once the e.coli bacteria infects a human being, the person will experience diarrhea and abdominal pain, both from the bacteria

How does the effectiveness of natural remedies ability to inhibit growth of E. coli compare to that of antibiotics?

All people are at risk of contracting the E. coli disease but some are at a higher risk than others. A person is at risk when they swallow the bacteria through food or water that is infected with the E. coli bacterium. Eating meat that is undercooked or consuming unpasteurized milk and raw milk products can also put a person at risk for the disease (Lim et al., 2010). People with low immune systems, the very young and elderly are very susceptible to contracting E. coli infection (Lim et al., 2010). Then people who are exposed to poor water systems and contaminated environments where E. coli bacterium can survive are also at high susceptibility to contract the disease (Lim et al., 2010). When a person is infected with E.coli disease there is a period of time before symptoms starts to appear. Each case is different and symptoms vary. Once a person is exposed to this bacterium, then incubation begins. The time period for incubation is approximately a period of two to ten days. However the whole disease, barring serious complications and

Escherichia coli (E.coli) is a relatively large, rod shaped, gram-negative, fecal coliform most commonly found in the GI tract of warm blooded animals. There are several species of E. coli, most of which are harmless, but some are pathogenic. The most common pathogenic strain is Shiga toxin-producing E. coli, which come from the gut of farm animals and some wild game. Consumption of unpasteurized milk or meat that has not been disinfected spreads the bacterium. Symptoms include stomach cramps, diarrhea, fever and vomiting.

Escherichia Coli is a bacterium that inhabits the gastrointestinal tract of both humans and animals. E. coli isn’t always a harmful bacterium. Some are actually crucial to a healthy intestinal tract because this bacterium assists with the production of Vitamin K2 and stops pathogenic bacteria from interacting and establishing inside the intestines (Gould, 2010). A person maybe exposed to E. coli through water or food that maybe contaminated or from raw meat such as ground beef or raw vegetables. Lack of good hygiene is another way that E. coli infections can spread especially in places such as hospitals or day care centers. While a healthy adult with an E.coli infection will most likely recover within five to seven days, those who are at risk include young children, elderly and those with a weak immune system.
