The Effects of Transmissible Spongiform Encephalopathies on Humans Essa

The Effects of Transmissible Spongiform Encephalopathies on valet de chambreAbstractHumans have to deal with many different maladys and the ones most disliked ar the ones with no cures. Like cancer, transmissible spongiform encephalopathies have no cure, but they ar more rare. These diseases are prion diseases which cause the brain to deteriorate. Prions are proteins that sometimes birth like viruses, which mean that they should have some form of nucleic acid, but since they applyt, they cause supernormalities. The nervous system contains many normal prions, but when an abnormal prion comes along, it transforms all the normal prions into abnormal ones. Bovine spongiform encephalopathy is found in cattle, but it can be transmitted to humans. The Creutzfeldt-Jakob disease affects the senile for reasons unknown, mend Kuru affects those who practice cannibalism. Scrapie is found only in sheep and the Chronic Wasting indisposition is found in deer and red deer. As of right now, Kuru and Scrapie are non known to infect humans.Prion diseases affect many animals, such as cattle, sheep, deer, elk and humans. All mammals have prions, which are proteins that are found abundantly in the nervous system. The brain contains the most prions and is therefore dominantly affected by disease. The prion disease found in cattle is called bovine spongiform encephalopathy, or mad terrify disease. Humans contract this disease by eating infected cows. The elderly usually contract the Creutzfeldt-Jakob disease for reasons unknown, and Kuru, which is extremely rare nowadays, is contracted by cannibalism. Scrapie infects sheep and the Chronic Wasting Disease infects deer and elk. Though there is no link to either Scrapie or Chronic Wasting Disease infecting humans, it is ... ...missible Spongiform Encephalopathies 6References American vet Medical Association. (2002, May).
