A new method for rapid detection of BSE pathogens invented by Austria

Introduction: scientists from Kepler University, Austria, have developed a high sensitivity fluorescence microscope and a special antibody The combination of the two can quickly determine whether the living cattle contain the pathogen of BSE Most of the pathogens of BSE are concentrated in the brain and spinal cord of cattle, and the content of BSE in the blood of cattle is extremely rare Many scientists around the world are engaged in the study of BSE detection in live cattle, but no effective method has been found so far Scientists from the Institute of physiology at Kepler University have developed a high-sensitivity fluorescence microscope, which can detect tiny molecules in the blood that could not be seen before, so as to determine the pathogen of BSE in the blood of cattle Hans Georg Schindler, director of the Institute of physiology at Kepler University, said that researchers have also developed an antibody with dye molecules that can emit a certain color light When the antibody is added to the blood sample, it will attach to the diseased protein With the help of the new high sensitivity fluorescence microscope, the pathological proteins can be found according to the specific color light Shendler said that using this new method can accurately and reliably determine the pathogen in the blood in a few minutes with only one drop of blood, which is much better than the existing method In addition, the new method can also be used to determine harmful substances such as edible water or food According to Schindler, this "pioneering" method can not only eliminate the need for mass killing of live cattle when mad cow disease occurs, but also be used in people in the future to detect pathogens of various diseases in human blood as early as possible But schendler predicts that it will take another year and a half to two years for the new method to be widely used for the detection of BSE, and about five to 10 years for the detection of early human diseases According to media reports here, the government of Austria's upper Austrian state, where Kepler university is located, attaches great importance to this achievement, saying that it will allocate more research funds "to prevent this technology from flowing abroad."
