What is beef spongiform encephalopathy?

Beef spongiform encephalopathy is a brain disease that affects cattle. It is also known as a disease of crazy cows. The very nature of this disease is not fully understood, but scientists believe that it is caused by a protein called prion rather than some kind of bacterial infection or virus. This protein gradually causes the tissue in the brain to become mushroom, which eventually leads to death. Beef spongiform encephalopathy can be extended to people who eat the meat of infected cattle, and in animals and humans it is always deadly.

When the cattle is infected with this disease, the first thing that changes is their behavior. They can become aggressive or nervous. After a while they begin to develop motor problems and may have problems with walking or position. Eventually they begin to lose weight and waste away.

When people have illness, their motor skills are getting worse and they can gradually lose memory. When the disease first begins, they have emotional or psychiatric problems and changes in their behavior.Sometimes they can become depressed or can be angry with their family members.

It may take years after exposure to symptoms to appear in both humans and animals. Scientists believe that the disease is transmitted by the food of the brain tissue of an infected animal. Sometimes a small amount of brain tissue may occur in minced beef, and usually people withdraw this disease. It is very difficult for beef spongiform encephalopathy to be transferred to humans, even if they eat contaminated tissue.

cows also contrast beef spongiform encephalopathy by eating sick brain tissue, and this happened because many animals for animals were made using the remaining parts of cattle. Laws have been passed to limit the use of this type of feed, and these measures were relatively successful in reducing events around the world of beef spongiform encephalopathy.

Most cases have been reported in the UK and in JEdnom of the moment was a huge epidemic, with thousands of new infected cattle every week. The first cows ever acquired this disease were infected in the age of 70, but until the middle of the 80s were not ill. British beef spongiform encephalopathy epidemic achieved peak in 1992 and 1993.

Most human cases were also British citizens. Scientists say that people can reduce their chances of developing illness by focusing on steaks and roast than minced beef, because these meat are much less likely to be contaminated. There is no way to test this disease until someone dies, but scientists can usually zero as a probable diagnosis based on symptoms.
