The Effects of Transmissible Spongiform Encephalopathies on Humans

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. 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.

Humans are susceptible to many different diseases and unfortunately, these transmissible spongiform encephalopathies have death written all over them.
Transmissible Spongiform Encephalopathies 2
Should people really fear eating beef because of the possibility of contracting bovine spongiform encephalopathy? Probably not since one can only contract this disease through the consumption of contaminated meat. If a non-contaminated part of an infected cow is consumed, the person would not contract this disease. If one is unfortunate enough to consume a piece of contaminated meat, it is basically his/her death sentence because his/her brain will slowly deteriorate through abnormal prions that pass the immune system as a normal prion.
The meats that consumers eat are slabs of a cow’s muscle tissue and the infectious meat is only found in the nerve tissue. Of course there is the possibility of having some of the contaminated meat passed on to the meat that consumers eat when the cows are cut, but the chances are very slim. Since this disease is contracted through eating contaminated meat, the site of infection should be in the digestive tract, yet this disease eats away at the brain and nervous system.
The abnormal prions from the contaminated meat invade the nervous system to reach the brain, where they eat away and create holes that make the brain look like a sponge. The person slowly loses his/her
