E. Coli Bacteria Case Study

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

According to data, the natural antibiotics worked better for defending against Bacillus cereus. The Oregano Oil and the Garlic had tied for first and proved to have the largest zone with a length of 18 millimeters between the disc and the bacteria after 48 hours of growth. For a bacteria such as “Food Poisoning” the final result was shocking that the least amount of growth was for the man made antibiotics because they were specifically made to fight these types of Bacteria. The final result for Gentamicin had proved it to have a much smaller zone of inhibition with a zone of just 12 milimeters after the 48 hour time period. The growth of the penicillin was the lowest of them all with the very small zone of 0 millimeters after the 48 hours.

Escherichia coli, or better known as E. Coli, is one of the most commonly studied single-cell organisms because it is easier to manipulate and it is abundant. Some E. Coli strains can be pathogenic, but most are harmless. They can help benefit digestive health by filling niches in place of more harmful microorganisms. Because it is a diverse group of related microorganisms, it can be difficult to find the boundaries defining the species. Some strains are natural while others are genetically created in labs, which can be observed in aspects of an organism (Schussler).

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

The antibiotics will have different zones of inhibition on different bacteria. Also, a range of concentrations of the nutrients in the bacteria will change the bacterial growth.

The aim of this investigation was to find out which antiseptics were most effective at preventing the growth of bacteria.

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.

At the end of 2006 both Iowa and Minnesota suffered an out break of E.Coli from Taco Johns. The restaurants that were affected were in Cedar Falls, Albert Lea, and Austin. In December of 2013 Iowa health officials recorded that at least 50 of its residents became ill with E. coli and 27 from Minnesota. January of the following year the Food and drug administration stated that the FDA was close to identifying the source of the E. coli break out. According to the FDA 81 individuals became ill. 26 of those ill were hospitalized with E. coli infections and two even developed hemolytic uremic syndrome.

1 and 3). This antibiotic is effective against both gram positive and negative bacteria, so it would be effective against Staphylococcus epidermidis. This antibiotic is able to kill bacteria by interfering with the cell wall synthesis, weakening it, and causing its death. However, just like with Penicillin, some bacteria have become resistant to this antibiotic (6). The hypothesis stated that Staphylococcus epidermidis would be susceptible to Ampicillin because although some bacteria have become resistant this one has not (7). According to the class data, two of the tests resulted in in susceptibility, one resulted in an intermediate effect, and the rest were resistant (see Figs. 2 and 5). It seems that Staphylococcus epidermidis is in the process of becoming resistant to Ampicillin because of the varied data. However, the group data did not support the hypothesis that the bacteria would still be

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.

Phones hold an alarming amount of bacteria on them, being that every 8 in 10 phones hold pathogenic bacteria. A pathogenic bacteria is a type of bacteria that will get a person sick and can be potentially life threatening. A common type of pathogenic bacteria found on phones is e.coli. E.coli is a bacteria that can be obtained from uncooked meats, unsanitized water, and anything fecal contaminated. Although e.coli can be a dangerous bacteria outside of the body, it plays an essential role in the large intestine, and it produces vitamin k which cannot be found in foods. One solution to killing bacterias like e.coli are to use disinfectant sprays. The problem with disinfectant sprays is that one will never actually know if they are working or

While Shapiro et al. was not able to recommend antimicrobial prophylaxis with amoxicillin Nadelman et al. devised

Antibiotics are important for the treatment of bacterial infections, and it is therefore important to know how different antibiotic works in different contexts. Different kinds of bacteria are affected to different degrees by different antibiotics, and it may therefore be useful to know which antibiotic that attacks the bacteria. The purpose of this report is to analyze how antibiotics including Chloramphenicol and Ampicillin affect the growth rate of bacteria Escherichia coli and Bacillus subtilis. Which antibiotic is the most effective or least effective in inhibiting the growth rate of these two bacteria respectively?

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.
