...Ask and Answer Paper: Understanding Prions Ask and Answer Paper: Understanding Prions Steven English Ask and Answer Paper: Understanding Prions 1 As its name suggests, Pasteur's germ theory of disease simply states that microbes are the cause of disease. Though it seems obvious now, it was revolutionary at the time of its inception and is central to our modern understanding and treatment of diseases. It replaced the commonly held and relatively complex 'humoral theory' with a simpler concept that boiled down to a relationship between microorganism and host (“Germ Theory,” n.d.). But as our understanding of the disease process grows with more and more diseases continuing to be discovered, we find that while viruses and microorganisms might be the main cause they aren't the only way in which disease can spread. Prions are one such challenge to this simple germ-disease paradigm. In this paper, the following questions about prion diseases (focusing primarily on kuru and Creutzfeldt-Jakob disease) will be examined: “What are they and what does their discovery mean for our understanding of disease and evolution?” The prion protein (PrPC) is a protein seemingly found in the brains of almost all vertebrate animals which...

...Report on: BSE Crisis Misconception of Risks & Flaws within the system Abstract The BSE or the mad cow epidemic was a major crisis in British history. The BSE disease was first identified in cattle in 1986. Though the cause of the disease is not known till now, but how the disease spread was known at initial stage. Contamination of BSE into cattle happens due to consumption of BSE contaminated MBM. There was a scientific assumption that BSE might not be transmitted to human, but there was a risk of contamination to human also. But policy-makers’ perception of risk was wrong and they were consistently assuring people that beef is safe to eat, and BSE is not transmissible to human. There existed a great divergence about the perception of risks between the scientists, policy-makers and the public. Message of risk was not communicated to public in fear of irrational over reaction or risks to the industry. Scientific risk assessment was understated and misinterpreted by the policy-makers’ risks assessment on economic views, and the public was kept unaware about the risks. The flaws and shortcomings that existed in the then system aggravated the crisis. It had become necessary to separate scientific risks assessment from the political risk assessments. The outbreak of the epidemic in 1996 after 10 years of denial brought disaster to the British beef industry and created sense of betrayal and mistrust among the public. To re-establish the confidence a wide range of reforms...

...Bad Bug Book Handbook of Foodborne Pathogenic Microorganisms and Natural Toxins Introduction Food safety is a complex issue that has an impact on all segments of society, from the general public to government, industry, and academia. The second edition of the Bad Bug Book, published by the Center for Food Safety and Applied Nutrition, of the Food and Drug Administration (FDA), U.S. Department of Health and Human Services, provides current information about the major known agents that cause foodborne illness. The information provided in this handbook is abbreviated and general in nature, and is intended for practical use. It is not intended to be a comprehensive scientific or clinical reference. Under the laws administered by FDA, a food is adulterated if it contains (1) a poisonous or otherwise harmful substance that is not an inherent natural constituent of the food itself, in an amount that poses a reasonable possibility of injury to health, or (2) a substance that is an inherent natural constituent of the food itself; is not the result of environmental, agricultural, industrial, or other contamination; and is present in an amount that ordinarily renders the food injurious to health. The first includes, for example, a toxin produced by a fungus that has contaminated a food, or a pathogenic bacterium or virus, if the amount present in the food may be injurious to health. An example of the second...

...Preface A well-developed knowledge of clinical microbiology is critical for the practicing physician in any medical field. Bacteria, viruses, and protozoans have no respect for the distinction between ophthalmology, pediatrics, trauma surgery, or geriatric medicine. As a physician you will be faced daily with the concepts of microbial disease and antimicrobial therapy. Microbiology is one of the few courses where much of the "minutia" is regularly used by the practicing physician. This book attempts to facilitate the learning of microbiology by presenting the information in a clear and entertaining manner brimming with memory aids. Our approach has been to: 4) Create a conceptual, organized approach to the organisms studied so the student relies less on memory and more on logical pathophysiology. The text has been updated to include current information on rapidly developing topics, such as HIV and AIDS (vaccine efforts and all the new anti-HIV medications), Ebola virus, Hantavirus, E. coli outbreaks, Mad Cow Disease, and brand-new antimicrobial antibiotics. The mnemonics and cartoons in this book do not intend disrespect for any particular patient population or racial or ethnic group but are solely presented as memory devices to assist in the learning of a complex and important medical subject. We welcome suggestions for future editions. 1) Write in a conversational style for rapid assimilation. 2) Include numerous figures serving as "visual memory tools" and summary charts...
