Transcript of Mad Cow Disease

Bovine Spongiform Encephalopathy a.k.a. Mad Cow Disease The disease is caused by prions. Prions are made of protein in a misfolded form. Mad Cow Disease isn't easy to characterize or destroy. Cattle get the disease from eating infected food, such as food that has rendered parts of infected animals inside of it. Yes, cattle graze, but their diets may be enhanced with protein from another animal. Cattle can't get sick right away from eating the prions. It can take up to several years for Mad Cow Disease to develop. The human variant of this disease is called Creutzfeldt-Jakob disease. It is a brain disease that is incurable and always fatal. This disease causes the brain to develop holes and takes on a spongy texture. You can develop CJD randomly or from a genetic mutation, completely unrelated to Mad Cow Disease. Symptoms (in humans) In cows the symptoms are alike, they include weight loss despite having an appetite and lack of milk production. Include the following: dementia memory loss personality changes hallucinations speech impairment jerky movements changes in gait rigid posture and seizures Technically, you can't get Mad Cow Disease, because you aren't a cow. Around 270 people have died worldwide from CJD since it was first identified around ten years ago. No one has contracted it in the United States. Approximately 188,600 cows have died worldwide from MCD. This was made by Allysah and Margaux.
