E Coli And Its Effects On The Environment

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)

Microorganisms are both beneficial and harmful. These microorganisms are important to humans because they play a role in the ecology of life, by decomposing wastes, both natural and man-made, such as creating nitrogen fertilizer at the root zones of certain crops. Other several pathogens that can cause serious harm, even immediate death due to the diseases or disease causing products they produce. Overall, microorganisms play an important role in life.

Before, biologists assumed all microbes are bad for the human body (automatically thought of pathogens), caused many diseases and harm our body fundamental systems. In addition, the biologists think that our body is already built which had all the functions required to maintain our health. However, the attitude has changed over the last decade. The biologists characterized the most prevalent species of microbes in the body, and found out that these collective microbes do not threaten us, and they also are important part of human bodies.

we are curing disease. As we use antibiotics, the rapidly mutating microbes grow resistant. While

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.

Chapter 9 of the literature shows the spread of bacteria called E. Coli 0157:H7 as well as its negative effects. E. Coli 0157:H7 was found in the beef and 25 million pounds had already been eaten. The food poisoning was spreading rapidly and 200,000 people got sick. Schlosser claimed that since there is bad in the meat that is why people are getting an ill eating hamburger. Americans were getting afraid and constantly people were getting infected, especially children, elderly, and people with impaired immune systems. According to the literature,“...progressed to diarrhea that filled a hospital toilet with blood… drilling holes in his skull to relieve pressure, inserting tubes in his chest to keep him breathing, as Shia toxins destroyed his

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

Bacteria are a very small, self-sufficient, one-celled organism that thrives in a variety of environments. However, many bacteria thrive in the mild 98.6 health body environment, some of these environmentally content bacteria in your body are actually good for you; its only 1% that isn’t.

During our class discussion last week, we discussed Microbes Help Grow Better Crops, by Richard Conniff. In the article by Richard Conniff, he states that, “Adding bacteria to a crop to prevent human disease could be the start of a whole new path to food safety.” This statement by Richard Conniff explains to us the idea of preventing diseases by adding bacteria to a crop. As a result, we will be able to prevent most human diseases from existing in the first place. We as a society haven’t implemented the idea about adding bacteria to crops yet, but suggesting ideas that can help prevent problems for us as a whole is the first step to making our future better for us. Diseases such as, salmonella and E-coli can be prevented with the new understanding

Microbes are everywhere and anywhere. Microbes can be found from on surfaces of our daily lives to microbes we encounter and spread on. Microbes have been always since life started in this planet. According to a BBC article about Earth, “…an older microbe came to light…to be a remarkable 3.5 million years” (BBC). As stated, microbes may be considered to have been here long before any other living organism, which means these microbes have evolved through time as well. With evolving comes the different types of bacteria that may benefit us and also harm us. Harmful bacteria such as Lyme disease and the Plague which both derive from an infected insect with different bacterium. These two different disease made different approaches to our history

Breaking news, 107 persons contacted Escherichia coli (E. coli) bacterial infection after visiting a petting zoo at a North Carolina County fair . . . a 2-year-old boy died.¹ E. coli bacterial infection is a growing concern for public health officials in the North Carolina Department of Health and Human Services and other local health departments. This is the most recent condition on E. coli outbreaks in North Carolina. In 2004, E. coli O157:H7 infection was responsible for making 108 visitors to the North Carolina State fair’s petting zoo ill.¹ This condition posed a serious health risk to the unsuspecting petting zoos’ patrons. Kids are more susceptible to these kinds of infections, because they are more prone to touching animals on display; then touching their mouths, noses, and eyes, which can lead to autoinfection. Most people are unaware of the infectious danger that lurks in the innocent coats of these cute furry creatures.

Life is full of bacteria that can be beneficial and harmful at the same time. They are the smallest living things that can be found everywhere in the air, soil, water, and even in our body. We actually share our body with many bacteria. Therefore, without the good bacteria we could die because the good bacteria can help digest the food we eat and protects us from bad bacteria that make us sick. On the other hand, living with those organism can be harmful and can cause many diseases. Some of these diseases are produced when bacteria attack the tissues in a plant or animal. Also, it can attack organisms by releasing chemicals. Therefore, they can cause damage to a persons body. These pathogenic organisms are able to reproduce rapidly and split into two identical copies of themselves.

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.
