Escherichia Coli And Its Effects On Our Health

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

Esherichia coli also known as E. coli is a bacterium that lives in your gut. (1). it was founded by Theodore von Esherich in 1888. There are many people that can get the bacteria. Also there are thousands of strands of E.coli. Six E. coli O157 outbreaks were identified during 2007. Four of the outbreaks involved foodborne transmission. (Eshericha Coli). Six Minnesota cases and one Wisconsin case with the same or closely-related PFGE subtype of E. coli O157:H7, and an additional Minnesota case of Shiga-toxin producing E. coli that was not culture-confirmed, attended the Minnesota State Fair in August. All but one of the cases showed cattle or visited the cattle

Escherichia coli are rod shaped, gram negative bacteria often found in the gut of humans and other warm-blooded mammals (Jacques & Ngo, 2004). It is transmitted primarily through faecal contaminated food and water. Most strains of E. coli are not harmful to humans, however some strains are pathogenic and can cause symptoms including diarrhoea (Unknown, 2012).

BACKGROUND – E. coli is a food-borne bacterium that inhabits the bowels of warm blooded creatures such as humans and animals. If the individual is infected by E. coli, some symptoms can be “diarrhea, gas, abdominal cramping, fatigue, fever and vomiting.” (Pietrangelo”) If someone is infected with this bacterium, anti-biotics, which is explained by Oxford Dictionaries as “A medicine (such as penicillin or its derivatives) that inhibits the growth of or destroys microorganisms” can successfully treat the disease if it is outside of the digestive tract.

Escherichia coli O157:H7 causes 73,000 illnesses in the United States annually. A review of E. coli O157 outbreaks reported to Centers for Disease Control and Prevention (CDC) to better understand its epidemiology. E. coli O157 outbreaks revealed that in that period, 49 states reported 350 outbreaks, representing 8,598 cases, 1,493 (17%) hospitalizations, 354 (4%) hemolytic uremic syndrome cases, and 40 (0.5%) deaths. Clinical laboratories began examining more stool specimens for E. coli O157. In 1994, E. coli O157 became a nationally notifiable infection, and by 2000, reporting was mandatory in 48 states. Escherichia coli O157:H7 was first recognized as a pathogen in 1982 during an outbreak investigation of hemorrhagic colitis.

E. Coli is both a necessary bacteria in the human digestive tract and a very harmful toxin

Escherichia Coli, located in one of the main organs known as the large intestine, is a type of bacteria that helps digestion. (Trzepacz, Timmons, and Duobinis-Gray, 2016) For Escherichia Coli to remain stable and alive, it needs specific necessities. These needs are known as the following: Energy, vitamins, and similar compounds. Escherichia Coli is found everywhere!

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.

E. coli is a bacterium capable of being transmitted from one person to another. To ensure that the bacteria used in this experiment were not transmitted to other places, items, or organisms, several safety protocols were followed.

The orgimsms involved in Escherichia coli 0157 is an anaerobic bacterium which is shaped like a rod and is Gram-negative. Escherichia is a foodborne pathogen which causes a variety of disease in humans worldwide. Cattle are the reservoir to the diseases. Between 1% and 50% of healthy cattle carry or shed E.coli by means of their faeces. The cattle can also contract the infection after slaughter as conmtanation can occur during slaughter or while the beef is being proceed into products suitable for human consumption. In the United states the most common way of transmission of the disease is through consuming contaminated food and water. Although it is also frequently spread from person to person impartial in communities where there is a high concentration of children such as child care services and primary schools.

Escherichia coli (E. coli) is a bacteria usually found in warm blooded organisms such as human and animal intestines. Although there are large groups of E.coli, most strains are harmless. Other strains of the bacteria may cause diarrhea, respiratory illnesses and food poisoning. Some strains such as O157:H7 can cause kidney failure or severe anemia. Exposure to E.coli can be in the form of food, water, undercooked meat and even raw vegetables. Symptoms may include: nausea and vomiting, severe stomach cramps and stomach tenderness, diarrhea containing blood.

Escherichia coli (E.coli) has been a public health issue since the 1980s and is a major concern in food contamination in products like beef, dairy, and fresh produce. E.coli 0157:H7 itself is not invasive but it produces a Shiga toxin which attacks the host small blood vessels in the kidney. This makes the kidneys work harder which can destroy red blood cells and lead to hemolytic anemia (lowered number of red blood cells produced). The incubation period for E. coli ranges from three to eight days. The infection often causes severe bloody diarrhea and abdominal cramps, but can also cause non-bloody diarrhea or no symptoms. E.coli may greatly affects children and the elderly.

Every year over 96,000 people contract E.Coli, 3,200 of those people are hospitalized for E.Coli, and over 31 people die each year from E.Coli (Food News). E.Coli (otherwise known as Escherichia coli O157:H7) is a disease that is spread in many ways, the most common way being raw and uncooked food in the restaurant being served to the customer. Another way E.Coli is spread is through contact human/animal feces. E.Coli can be prevented, here are some ways to do so; Cook all meats to at least 160 degrees fahrenheit, wash your hands with warm water and soap (especially after touching raw meats), wash off all kitchen supplies thoroughly, use only pasteurized dairy and juice products, use/drink treated water, If you travel to another country that may have unsafe water don’t use tap or ice water, avoid raw fruits and veggies (Web MD).

I had recently experienced the terror that is referred to as E. Coli. I can tell you all about how it is much worse than the flu, although I will also be talking about this one girl I stumbled upon on the internet also. She had a life threatening experience that you can definitely experience if you go untreated when finding out that you have E. Coli. She had it for 19 days straight when I had been extremely lucky that I had only had it for eight days. I know that I definitely did not feel lucky, but doing this project has let me realize that I was very fortunate. Some people just chalk it up as the stomach flu like my mother and aunt did, but my grandmother knew it was something more than that. She ended up taking me to Med Express which is not a very good place to go if you want to get a work release on the same day or week by the way. On top of the issues I had at the doctor it was nonstop viral- like symptoms that only got worse until they got better.

E. coli O157:H7 is a gram negative, rod shaped bacteria that is being found in many foodborne and waterborne illnesses. It is also called Hemorrhagic colitis, the acute disease caused by E. coli (EHEC) because it causes abdominal pain, and bloody diarrhea. It generally lives in the intestines of healthy humans and is generally harmless. It is also found in healthy cattle and can contaminate meat during slaughtering, as it produces a toxin that can cause illness. The E.coli O157:H7 is rare variety of E. coli that produces large quantities of one or more related, potent toxins that cause severe damage to the lining of the intestine. The Verotoxins that cause the disease are also called shiga toxins, because they were acquired from the Shigella strain. It is believed that the widespread use of antibiotics by American farmers has promoted the transfer of antibiotic resistance genes and pathogenicity islands that has led to the creation of new pathogenic strains such as E. coli O157:H7.
