Diagnosis of mad cow disease by urination

Introduction: the cause of spongiform encephalopathy such as mad cow disease is the variation of prion's egg Up to now, this kind of egg in the brain of cattle and human can not be reliably detected in the blood sample of the diseased organism, so it is very difficult to diagnose However, using the method of experts from hadassa Medical College in Israel, people can easily detect a special protease structure in urine samples, so as to infer the existence of prion protein What's more, this test can confirm whether the organism is infected with the disease long before symptoms appear The research results of experts in neuroscience of hadassa medical college were published in the Journal of biochemistry in June It is reported that the medical school recently carried out a successful test: 50 urine samples of cattle infected with BSE were sent from the UK, mixed with healthy urine samples of cattle, and all 50 samples were detected without knowing the exact number of sick cattle samples This convenient and cheap urine test method will bring good news to the animal husbandry affected by mad cow disease In the past, once a case of BSE was found in an area, due to the lack of simple and reliable detection methods, all cattle in this area were often killed to avoid the spread of the disease But now, there is no need to kill a large number of healthy cattle through urine sample testing, avoiding the huge economic loss of animal husbandry In addition, in the past, people in the epidemic area of mad cow disease have been banned from donating blood because of the fear that there has been a mutation in the blood Now, the urine sample test method can easily return the clean to the healthy epidemic area population, and is conducive to the early warning of patients However, experts from hadassa Medical College point out that the presence of variant prion protein in urine will cause people to be alert to the spread of BSE through urine.
