The Escherichia Coli bacterium was discovered in 1885 by bacteriologist Theodor Escherich. He found the bacteria in the human colon and showed that some strains of Escherichia Coli were responsible for infant diarrhea and gastroenteritis. The Escherichia Coli was originally named Bacterium Coli. The name was changed to honor Theodor Escherich. E coli are normally harmless and are part of the normal flora found in the lower intestines of humans and healthy cattle. Some E. coli serotypes are known

their food intake is through meat and dairy products and it’s not a lie when people say the food industry is a bunch of shady people. Past generations have been able to eat raw beef without even considering consequences like e-coli‚ but at this point in the United States e coli is the least of our worries. It is time to stand up against the food industry and make a change for the better of our world‚ and our future generations. The United States is a country where food is being mass-produced. We

General information: What is E.coli? Escherichia coli‚ or commonly referred to as E.coli is a foodborne pathogen that normally inhabits in the intestinal track of humans and animals. It is the most common and wide spread infecting organism and is in the family‚ Enterobacteriaceae. Enterobacteriaceae is a large family of Gram-negative bacteria‚ meaning the bacteria appear pinkish or red. How fast and how does it spread? The main way that E.coli can spread is through food and water supply. Common

Escherichia coli also known as E. Coli‚ is a type of bacteria which thrives in polluted water. Many people will come in contact with this type of bacteria in their lifetime. In fact‚ E. coli is normally found in the intestine of humans and animal where it plays a significant role in the digestive system. The bacteria can also be found in raw meat and uncooked vegetables as well as polluted water. Most of the strain of E. coli are harmless therefore they will not cause illness if consumed. “One of

1) TITLE (2pt): Testing antimicrobial props in soaps 2) INTRODUCTION (6 pts): In this experiment we wanted to test how effective different types of soaps against E. Coli. For this experiment we were interested in looking at antimicrobial soaps vs. non-antibiotics soaps in their effectiveness to kill E. Coli. The protocol that we used was the Kirby Bauer technique. This technique was used to test the antimicrobial properties of each soaps. (“Kirby-Bauer” 2015). 3) METHODS (6 pts): We first started

This article is about public and private swimming pools being contaminated with E. coli. Chlorine is not doing its job in sanitizing the human waste in the swimming pool. Human waste seems to refuse being sanitized. The Centers for Disease Control (CDC) concluded that the E. coli came from one major primary source; swimmers pooping in the swimming pool. Researchers say such contamination is due to swimmers not rinsing themselves off before going in the pool. Scientists say a person carries about

RESULTS AND DISCUSSION E. coli and S. aureus were tested to determine effectiveness of photodynamic inactivation with the use of methylene blue as photosensitizer and blue LED as alternative light source. Table 1 shows the resulting number of colonies for each replicate of every treatment per bacteria tested. Each of the treatments was averaged to get the mean number of colonies per treatment. All experimental setups were produced in quintuplicate‚ however only three of the five replicates were
