A research team from the start-up company InsectSense and Wageningen University (Netherlands) has shown that bees can be trained to recognize the SARS-CoV-2 coronavirus and be positive within seconds. Insects can replace traditional diagnostic methods, in which it is difficult to test.
Because it is very sensitive smell, This Domestic bee (Apis mellifera) can identify Coronavirus SARS-CoV-2 immediately. In other words, they can “sniff” the virus.These capabilities insect Can be used for clinical diagnosis Coronavirus disease, Infections caused by pandemic pathogens, especially in countries without pandemic pathogens Molecule/antigen test enough. Bees can be trained to recognize the coronavirus within minutes and respond faster than any laboratory test. Scientists say they are very accurate, but of course very thorough research is necessary to participate. Hymenoptera Under management Pandemic.
A Dutch research team led by scientists from a biotech start-up company determined that honeybees can recognize the SARS-CoV-2 coronavirus. Insect sensesWorked closely with colleagues from the Insect Laboratory of Wageningen University and Paul Sabatier University in Toulouse, France. Scientists coordinated by Professor Wim van der Poel, Professor of Virology at the University of the Netherlands, adopted a method called “Bee“, so that multiple bees can be trained at the same time and diagnosed by “spreading” them biological sensor. Scientists purchased bees from local beekeepers and trained them 150 times to identify SARS-CoV-2 through the following methods: Conditioned reflex Ø Pavlovian reflectionNamed after Ivan Pavlov, a Russian scientist who studies animal behavior.
First, the bees are “utilized” into the machine made by InsectSense, and then exposed to the SARS-CoV-2 coronavirus sample (both are Visoni of Infected man).Get rewards immediately after contact with samples syrup, Which is implied by extracting features Annoying Ø Booked. After repeating the operation several times, only in the case of exposure to the virus, the bees were drawn out of the tree trunk without being rewarded. In fact, the protrusion of the leaf tongue is a positive signal for SARS-CoV-2.Scientist at Press release Bees are very good at diagnosis, rarely False positive E False negative, Although the analysis results were not disclosed.
Interview From ReutersDirk de Graaf, a bee expert at Ghent University in Belgium, said that he believes that this technology cannot replace traditional systems to diagnose COVID-19, at least not in the near future. “This is a good idea, but I would rather use classic diagnostic tools to run tests than bees for testing. The scientist said: “I am a loyal bee lover, but apart from testing for COVID-19, I The bees are also used for other purposes. The professor added that insects have participated in many such experiments in the past, such as identifying Explosive, Other Hazardous Chemicals E disease, But the application in the clinical environment is still very complicated.Of course, bees have an excellent sense of smell when detecting chemicals, such as Pheromones he smell The light emitted by the flowers can even be detected far away from the hive.
