What is mad cow disease? Cow in Scotland with disease discovered



A neurological disease involving cattle was found in a cow on a farm in Scotland. Bovine madness, also known as bovine spongiform encephalopathy, is rapidly spreading and damaging the central nervous system of infected cows and killing them, according to the Center for Disease Control and Prevention. The disease causes unpredictable behavior in cows that are infected because it breaks the tissues in their brains.

The case found in Scotland has been isolated, the BBC reported. It occurred on a farm near the Huntly area and after the case was discovered, a movement ban was imposed on the herd on the farm.

The disease was found in an animal after it was dead, before it was converted into food, or came into contact with other foods for consumption, the BBC reported. There is still an investigation about where the disease might have originated.

This case is one of less than 20 found in the United Kingdom since 201

1. Regular tests are being conducted to screen animals for the disease, which can spread rapidly

In 1995, there were 14,562 cases of BSE in the United Kingdom and significantly fewer cases in the following years. How the disease spreads is not well understood by those who are studying the disease. It is known that the disease is transmitted by proteins called prions. What is unknown is how exactly it is transmitted so that another cow becomes ill with the disease.

Researchers believe the prion is made from a normal prion protein and becomes a bad protein that is harmful to the cows. In the 1970s, it probably started doing the rounds of cows, but the researchers are not quite sure.

According to CDC, there are indications of different types or strains of BSE or mad cow disease. There is the classic BSE found in the UK, and then possibly H and L strains, which are more common in the United States and Canada.

There is very little risk to humans because the cows were isolated and were not
