The mutations found in these mosquitoes could pose an 'unprecedentedly serious threat' if they spread further, scientists warn.
Wednesday in Science Advances, might add yet another concern to an already serious problem.
The research was led by scientists from Japan’s National Institute of Infectious Diseases, the country’s equivalent to the National Institute of Allergy and Infectious Diseases in the U.S. They studied samples ofmosquitoes recently collected throughout Asia, looking specifically for mutations in their voltage-gated sodium channel gene.
Lab experiments also found that these combination mutation-carrying mosquitoes were much harder to kill, with “substantially higher levels of pyrethroid resistance than any other field population ever reported,” the team wrote. In the title of their paper, they describe their results as the “discovery of super-insecticide-resistant dengue mosquitoes in Asia.”Kick back and unwind with an audiobook.
