Prion Diseases Essay

cannibalism has began the pattern of deadly prions that slowly begin to eat away at your brain and cause many life long diseases for many generations. This is all caused by a deadly little prion, which can be referred to as Spongiform Encephalies (Kuru: The Dynamics of a Prion Disease: Dr. Bindon), causes the brain to become spongy and have holes while dterteating the neurological functions along with the body (Kuru: The Dynamics of a Prion Disease: Dr. Bindon). Prions are able to come in many deadly forms

Variant Creutzfeldt-Jakob disease is an infectious and transmittable form of a prion, although extremely rare it still becomes highly fatal if infected. This disease can also be classified as a Transmissible Spongiform Encephalopathy (TSE) that is gained through exposure to the Bovine Spongiform Encephalopathy (BSE) from contaminated cattle or meat. As this is not a prominently spread disease around the world and considering it was only recognised in 1996 it has only held 175 cases in the United

and control disease around the world. Traditionally, a communicable disease is caused by one of three foreign agents: bacteria, parasites, viruses. While quite different, these four agents have much in common, including their adherence to Koch’s germ theory, their reliance on human hosts, and methods of transmission. In the last twenty years or so, however, the scientific community has encountered a fifth type of pathogen that is completely different in size, composition, and the disease it causes

Prion diseases or transmissible spongiform encephalopathies (TSEs) are a family of rare progressive neurodegenerative disorders that affect both humans and animals. They are distinguished by long incubation periods, characteristic spongiform changes associated with neuronal loss, and a failure to induce inflammatory response. The proteinaceous infectious particles, prion was identified by an American neurologist Stanley B. Prusiner and colleagues in 1982derived from the words protein and infection

Mad Cow Disease Bovine spongiform encephalopathy (BSE), better know as Mad cow disease is a relatively new disease. Most sources state that BSE first showed up in Great Britain in 1986 [Dealler p.5] but some say it popped up in 1985 [Greger p.1]. However the official notification was not until 21 June, 1988 [Dealler stats. p.1]. Spongiform encephalopathies are invariable fatal neurodegenerative diseases and there is no treatment nor is there a cure for this disease [Greger p.1]. The recent

(CJD) is a rare and incurable neurodegenerative fatal brain disease. The disease rapidly and severely affects the brain and progressively disables an individual by gradually destroying their memory, vision, ability to think and move voluntarily and function independently. It is one variety of transmissible spongiform encephalopathies (TSEs) and is categorized under a group of brain disorders known as prion diseases (Kraft, 2014). This disease is very rare affecting about one person in every one million

Prion Protein (PRNP) is encoded by a gene, which contains a highly unstable region of five tandem octapeptide repeats. An octapeptide repeat is a fragment from the protein which is composed of eight amino acids joined by peptide bonds, repeatedly copied along the amino acid chain. Within PRNP; these are tandem meaning that the octapeptide sequences are in such an arrangement that they are lined up one behind the other (Mastrianni, 2009). Prion diseases or transmissible spongiform encephalopathies

Because of the mysterious nature of the disease, the origin of scrapie and the damage it causes the body can only be theorized. The three main theories of scrapie and its structure’s effect on the symptoms it causes sheep and goats all present potential information about the disease and its cure (Scrapie Fact Sheet. August 2001: http://www.animalagriculture.org/scrapie/AboutScrapie/FactSheet.htm) The uncertainty

Although mad-cow disease is always fatal, it is not really much of a worry in the United States. There have only been four cases of mad-cow disease ever recorded in the United States. In every case, the United States Department of Agriculture has intervened and recalled tons of beef, 10,400 lbs. in the first case to be exact, in order to insure that the meat did not reach the plates of United States citizens. In Canada, however, there have been 19 cases of mad-cow disease. This differs considerably
