Escherichia Coli : An Important Food Borne Zoonotic Pathogen

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).

AIM – The aim of the experiment is to determine the relative effectiveness of several anti-microbial substances on developing pathogens. (E. coli)

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

O157:H7 strain of E. coli that sickened 40 people in eight states (Glausiusz 1). Additionally,

For the seven interviews that the team conducted, three of the cases had eaten hamburger or ground beef, no cases had drunk raw milk, only one case had traveled outside Michigan, no restaurant or social event was identified in common, all of the cases had consumed lettuce, and six had eaten alfalfa sprouts. Appendix A shows the line listing of people who became ill with E.coli or E.coli symptoms from June 15 to July 15. Based on those findings no obvious linkages between patients were found. Appendix B shows the epidemic curve for this outbreak. The epidemic curve showed that the onset of illness among cases occurred from June to July with largest number occurring on June 22nd. Based on the appendix D, DNA fingerprinting

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 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.

Scientifically speaking, Escherichia coli is a pathogen that is a bacteria that is Prokaryotic in nature. This bacteria presents itself as a gram-negative, non-spore-forming rod. This pathogenic bacteria releases toxins that invade the intestinal tissues and in cases of cystitis invade the tissues of the kidneys. The bacterium becomes attached by fimbriae to the epithelium tissue in the body then it causes inflammation of those affected cells.

E. coli usually resides in the intestines of humans and is beneficial to humans and animals. Most of the E. coli strains are not harmful, although some of the E. coli variants are pathogenic in nature and cause various intestinal problems (CDC, 2015). Meat usually contains bacteria,

One of the most common causes of food-borne illness is the bacteria Escherichia coli (PETA, 2011) that can be transmitted through ingestion of contaminated food and water and may cause diarrhea and vomiting. The most common manifestation of the infections caused by the bacteria is the gastroenteritis, an inflammation of the intestines that is a result from bacterial toxins that leads to vomiting and diarrhea, and urinary tract infections. The discovery of E. coli was made through the German bacteriologist Theodor Escherich where the bacteria was named after. It was considered to be an important public history (Marler Clark 2015). These bacteria usually lodge in the intestines of different animals including chickens where they are considered

coli strains can affect all parts of the human body. The bacteria is mainly spread through

The presentation for our group was to discuss E.coli 1057:H7. Each member of the group was responsible for focusing and explaining their assigned task for the disease. This presentation includes the signs and symptoms, environmental location, transmission, unique characteristics, prevention and treatment.

Escherichia coli are commonly found in lower intestine of warm blooded animals. Most E. coli are harmless. The bacteria can be grown easily and its genetics are relatively simple and easy to study, making it the best-studied prokaryotic organism. Certain strains of E. coli can produce toxins that can cause food poisoning when eating unwashed vegetables. (Wikipedia, 2010)
