Transmissible spongiform encephalopathy

Transmissible spongiform encephalopathies (TSEs), or Prion diseases, are a group of neurodegenerative disorders which include but is not limited to kuru, Creutzfeldt-Jakob disease (CJD), Gerstmann-Sträussler-Scheinker (GSS) syndrome, and fatal familial insomnia in men, natural scrapie in sheep, goats and mufflons. The first records of neurodegenerative disease which would later be linked to Prions were made about two hundred years ago. It was in the 1950’s it was discovered that Prion disease could

had studied a deadly brain disease in cattle known as Bovine Spongiform Encephalopathy (BSE) with a fatal variant human disorder called Creutzfeldt-Jacob Disease (CJD). Dorrell announced that the scientists had determined the consumption of beef was the likely explanation for Creutzfeldt-Jacob Disease. Scientist also concluded a new claim that both diseases were forms of another disease known as Transmissible Spongiform Encephalopathy (TSE) which is described to cause a formation of holes on your

The Effects of Transmissible Spongiform Encephalopathies on Humans Abstract Humans have to deal with many different diseases and the ones most disliked are the ones with no cures. Like cancer, transmissible spongiform encephalopathies have no cure, but they are more rare. These diseases are prion diseases which cause the brain to deteriorate. Prions are proteins that sometimes behave like viruses, which mean that they should have some form of nucleic acid, but since they don’t, they cause abnormalities

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 worldwide; in the states there are only about 300 cases a

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

Chronic Wasting Disease (CWD) is a brain disease in deer related animals that produces small lesions in the brains of diseased animals (CWD-Info 2013). Lesions are an area of severe tissue change in the brain (CWD-Info 2013). The lesions can range from harmless to very serious cases (CWD-Info 2013). Infectious parts of CWD are neither bacteria or viruses, but are thought as prions (CWD-Info 2013). Prions are dangerous proteins without nucleic acids (CWD-Info 2013). The prions break down the tissue

Deactivation of Prions in the Healthcare Setting Prions are infectious agents composed entirely of a protein material which is transmissible to other prion proteins leading to disease in a manner that is epidemiologically comparable to the spread of viral infection. Prions composed of the prion protein are believed to be the cause of transmissible spongiform encephalopathies among other diseases. All known prion diseases are untreatable and fatal. . Prions, however, are infectious by their effect

severity, swiftness with which it ends life, and its ability to exist undetected without symptoms for decades unless one’s family history is known. Fatal Familial Insomnia, (FFI), is a neurodegenerative prion disease classified as a Transmissible Spongiform Encephalopathy, (TSE), meaning that it is genetically transmitted (Belay, 1999, p. 284). FFI is autosomal dominant (Xie et al., 2013, p81-90), meaning that an individual with A or AA alleles, a component of a gene pair, could carry this gene (Ireland

In the last 13 years, cases of Chronic Wasting Disease have increased to over 25% in bucks and over 10% in does (Marien). With CWD being such a deadly disease, the rising percentage of cases has led to decreasing deer populations. Because the spread of CWD has resulted in many deaths, fewer hunting tags are allowed in affected areas to help the deer herd get healthy again. It is possible, though, that as the populations grow back, CWD may also become more prevalent. Actually stopping this tragic

The United States is an ecologically rich and diverse nation. Ever since the United States became a country so many years ago, they have remained one of the places that everyone from all over the world strives to make a living in. But what if in the future the United States couldn't offer people the basic needs of life such as water, food, land, and clean air? Well that harsh reality isn't too far away after all. Due to the increase in land and water usage in the United States it has become a
