E. coli is a very common discussion and sickness known around the world today. Many people hear about E. coli and immediately assume the worst. E. coli is a virus everyone should be aware of more than just the name and how it actually works. E. coli has many strains that it is related to but the one that is focused on in this paper is the 0157H7. The discussion of this paper is to inform people on what E. Coli is, how it creates the toxins to create the virus 0157H7, how it works in the body, what it specifically effects in the body, how it is protected against the gut acids, the reactions our bodily functions respond to the virus, and how the immune system will respond to it. It will also help what we understand about Bovines disease and the people who are not infect as well as why they are not infected. Furthermore show what makes their system more effective in preventing the 0157H7 from overrunning their system versus how we are affected by it. E. Coli also known as Escherichia coli, is a gram-negative bacteria that can survive in an environment with or without air and, depending on the environment, may or may not produce thin hair-like structures that allow the bacteria to move and to attach to human cells. This bacterium commonly lives in the intestines of people and animals all over the world. There are over 700 strains of E. coli . This bacterium is needed to breakdown cellulose and it also assists in the absorption of vitamin K. As long as the E. coli strain stays in the small intestine and in the colon they will not cause any infections because they are non- pathogenic but once they leave they can cause numerous bodily infections and reactions such as bladder infections, diarrhea, and also cause the release of poisons to cause you intestines to inflame. E. coli was given its name in 1885, after a man who is credited for being the first pediatric infectious disease physician, Theodor Escherich.

The strain of E. coli known as 0157H7 is one of the main strains that is identified and is broken down as such; the first number represents the molecules on the bacteria’s surface of the gram negative bacteria which is identified through numerous tests. After the number 0157 which is a specific stereotype strain, it is followed by a letter, in this case, being the letter "H" which are the protein antigens and lastly followed by a number identifier “7”. The protein antigens are different types of flagella that make the bacteria motile . This specific strain is the main harmful form that attacks humans mostly to children and the elderly. This particular virus kills on average 70000 people a year. E.
