E. Coli

Paper Summary:

This a detailed, and well researched paper discussing how e. coli can be prepared and used for study of Molecular genetics. The author looks at how e.coli lends is an ideal candidate for this area because it is such a simple organism. The paper also examines how scientists have been immeasurably helped in their progression of learning about the fundamentals of molecular genetics by the fact that E. coli can be induced into competence through a number of methods. The paper includes numerous illustrations.

From the Paper:

"Most of us, when we think of Escherichia coli at all, tend not to have very pleasant associations with the organism. It is in fact among the organisms that are most likely to affect (and infect) households. While E. coli is actually an integral part of the normal gastrointestinal flora, certain strains can cause diarrhea, fever and vomiting by one of three ways: by giving off toxins, by directly invading the mucosal lining of the intestinal wall, or by adhering to the intestinal wall. A person infected with E. coli may also have malaise or overall weakness and abdominal cramps. And a new virulent strain of E. coli, which is passed to humans via contaminated and improperly stored or prepared food, can cause a fatal kidney condition a finding that has prompted public health and food industry officials to suggest changes in the meat-inspection process, including the irradiation of some ground beef. But the bad name that E. coli deserves as a very nasty bug that infects humans must be offset by the fact that study of this organism has vastly increased our understanding of the field of molecular genetics. This paper outlines some of the most important basic principles of this field by focusing on the specific findings that studying E. coli have allowed scientists to derive."
