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

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

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

data on the growth of Escherichia coli (E. coli) and to monitor how it grows under certain conditions. It has been demonstrated that the levels of glucose and dissolved oxygen were found to affect the rate of growth of E. coli proportionally with a lack of oxygen resulting in the lowering of the pH. In this experiment the growth of E. coli was studied at constant temperature (37 0C) at which it grows ideally. Experimental results for the growth of Escherichia coli showed good agreement with theory

Well what scientist recently discovered is that this certain mutated bacteria actually will color urine to help diagnose medical diseases. So perhaps this mutated E. coli can make diagnosing certain issues a quicker process than before. One disease this E. coli mutant helps diagnose is diabetes.
