Rapid detection of BSE in vivo invented by Germany (12.22)

OA show ('918 '); bergingen Ingelheim pharmaceutical company in Leifa, Germany, recently disclosed that the company has invented a rapid detection method of BSE, which can quickly find out whether cattle are infected with BSE without killing them So far, it is only after killing the cattle and testing the brain tissue that we can determine whether they are infected with BSE There is also a risk that some infected but unexposed sick cattle will be slaughtered and eaten as healthy cattle The new rapid detection method can quickly determine whether the cattle have been infected by the blood test of live cattle This shows that the sale of slaughtered sick cattle can be completely eliminated in the future Yanott, general manager of vetmedia, a subsidiary of Bergen Ingelheim pharmaceutical company, said the method they developed was similar to the blood glucose test used to check diabetes First, the mad cow anti enzyme separated from the diseased cattle was treated with luminescent agent, then it was mixed with the blood sample taken from the tested cattle, and then all the interfering components such as bacteria and virus were cleaned with a kind of "detergent" The enzyme treated with luminescent agent will search for the pathogen of BSE in blood samples, once found, it will be identified immediately In this way, the inspectors "can judge according to the staining method" whether the subject has been infected with BSE This new method costs 150 marks per test, which is 50 marks cheaper than the current method In addition, the test only takes 20 minutes to get results Yanott said they "have three to four weeks to finish the whole lab work." If all goes well, the new method will be "officially put into use by the end of summer 2001" QKD (author:)
