E-Coli Bacteria

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

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

One of hundreds of strains of the tiny germ Escherichia coli, E. coli O157:H7 is a newly-visible cause of food carried/held and waterborne sicknesses. Although most strains of E. coli are harmless and live in the intestines of healthy humans and animals, this strain produces a powerful poisonous chemical and can cause extreme illness. E. coli O157:H7 was first recognized as a cause of illness during an outbreak in 1982 traced to contaminated hamburgers. Since then, most infections are believed to have come from eating undercooked ground beef.

There are major effects in the United States and Europe to help identify the role of microbial communities in the human body. The colon requires a balance of microbial agents that assist with various functions of the body. An imbalance can lead to C.diff., irritable bowel disease (IBD), irritable bowel syndrome (IBS), neurological disorders, and obesity just to list a few. Many of these problems have grown to an epidemic proportion. Both the United States and Europe have started projects aimed at the microbial communities of the body and their roles in our health.

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.

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.

2. List what it is caused by (specific scientific and common names of the organism: Escherichia coli

The E. coli bacteria are a native flora of humans and animals intestinal track, and it is

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.

Assume you’re at home your eating peanut butter and jelly sandwich. You turn on your television, and found out that the peanut butter you were eating was recalled. The new anchor explained that the brand that you consumed had E. coli. The anchor also explained the potential effects of E. coli bacteria. Later that day, you experience severe diarrhea, vomiting, and severe abdominal pain. The first thing that may come to mind is “What caused the E. Coli outbreak?” On the other hand, you may be thinking “Why didn’t the company take any precautions to reduce the potential outbreak? “The above questions are only important when evaluating the food industry. To reduce the food borne illness one follow the safest guidelines to protect public

Escherichia Coli, or E. coli, resides in the large intestine where it assists digestion and make up essential molecules like Vitamin K. For the most part, E. Coli poses no threat although there are few disease causing strains that can cause mild to severe food poisoning by finding its way into food supply (Timmons, Trzepacz, Duboinis-Gray). Enteropathogenic Escherichia coli, or EPEC, is a strain of diseasing causing E. Coli that is the leading cause of death in children with diarrhea in many parts of the world. EPEC colonizes in the intestine allowing the host to be invaded which can spread from person to person (Pearson, Wong fok Lung, Hartland, Giogha). Another strain of disease causing E. Coli also causes diarrhea in children is the DEC

During this report the demonstration will establish an awareness to the audience, which discovers the statics and findings of the results based on samples from a mathematical strategy perception. This possibly identifies the conclusion of the significant evidence of exposure with the amount and levels of unwanted consumption of E. coli in the Village of Sierra Leon’s drinking water. During the 5 weeks the missionaries have to achieve safer drinking water for the village, through three types of sampling using one hundred for the first and second tests, and twenty for the final evaluation. The population discovery consists of various elements such as the mean, median, and mode. That offers presentation for the average center tendencies.

There are some factors with microbial that play a part in our bodies. There is a virus called Escherichia Coli bacteria, E-Coli for short, that in culture, they thrive

Escherichia Coli is a bacterium that usually lives in the intestinal tract of a healthy individual. Most forms of E. Coli are harmless, but some can cause severe illnesses. E. Coli is known for contaminating foods and beverages. E. Coli can be on ground beef if not cooked all the way. That is why they’re strict food safety laws are enforced. Chefs are not allowed to handle ground beef and then vegetables. These laws prevent an outbreak from happening. Although, cross contamination happens more often than realized. The most common type of harmful E. Coli is O157:H7. It causes illnesses and in some cases death. The CDC also warns against another Shiga toxin-producing E. Coli (STEC). This form of E. Coli is called Non-O157 STEC.

In this lab experiment, students had to create a growth curve for E. coli. The E. coli growth curve would illustrate the progression of the population of E. coli a set time period. In this case, the growth curve depicted the population of E. coli over a 12-hour period. The growth curve for E. coli was created from the absorbance levels, the optical density(OD), recorded from the spectrophotometer.
