Ecoli
Escherichia coli (E. coli) is notorious for its adverse effects on the human body. A bacterium that normally lives in the stomach, some strains of E. coli can cause illness such as diarrhea. The strains most harmful to human beings include E. coli O157:H7 (Mayo Clinic Staff, 2011). Food and water contaminated with these harmful strains of E. coli are usually the means by which the bacteria is transmitted; adults usually recover but some patients with weakened immune systems including the elderly and children may die from an E. coli infection (Mayo Clinic Staff, 2011). Therefore, it is important to understand the role and various manifestations of the E. coli family of bacteria. Less is known about the potential benefits of E. coli. Some strains of E. coli are touted as beneficial intestinal flora, much like probiotics such as acidophilus. For example, Ruud (2001) notes that the health benefits of the Nissle strain of E. coli include a stimulation of the immune system, a reduction in irritable bowel syndrome symptoms, a reduction in ulcerative colitis, and a reduction of inflammatory bowel disorder. In addition to these potential health benefits, E. coli may also combat Crohn's disease as well as celiac disease (Ruud, 2011).
E. coli is used to create indigo because the bacteria plays host for the proteins used to create it. E. coli JA300 and its cyclohexane-resistant mutant, OST3410 were found to carry the genes that produce indole and its by-product indigo (Douky, Toyoda & Aono, 2002). Lee & Lee (2003) call E. coli a "model organism for the expression of heterologous proteins," and "an ideal organism for testing new analytical technologies because of the...

Fast Food advertising has been allowed to profess anything, from the 'healthy quality' of their food to the food company's contribution to homeless kids. While fast food giants are quick to take any of their detractors to court for any erroneous allegations made by members of the public, it doesn't stop these same companies from committing libel themselves through their promotions. However, most fast food companies steer clear of making
Given a mosquito's vastly shorter life span, preventing the spread of the infection to more human hosts greatly reduces the number of viable parasites in existence (CDC 2009). 10) There are several reasons that viral infections are more difficult to treat and diagnose than bacterial infections. For one thing, viruses are not truly alive, and this makes it difficult to kill them. They are essentially packets of genetic information in tough
Water Privatization How Privatization of Water is Bad for the World Water is a scarce resource, a fact that is becoming more evident as time goes on and pollution becomes more evident. There are many instances where privatization has been beneficial; bureaucratic red tape often makes policy making a headache for consumers, and some eagerly advocate for privatization of certain resources. Privatization often has advantages, but in many instances it also realizes
In 2002, "President Bush signed into law the Public Health Security and Bioterrorism Preparedness and Response Act of 2002, which, among other things, eliminated the need to convene an advisory committee to amend the list of diseases" listed as quarantineable (Misrahi, Foster, Shaw, & Cetron 2004). This law became significant during the SARS scare. Before 2002 "the list of federal quarantinable diseases in the United States had not been revised
Christian Biotechnology: Not a Contradiction in Terms Presented with the idea of "Bioethics" most people in the scientific community today immediately get the impression of repressive, Luddite forces wishing to stifle research and advancement in the name of morality and God. Unfortunately, this stereotype too often holds true. If one looks over the many independent sites on the Internet regarding bioethics, reads popular magazines and publications, or browses library shelves for
