Genetically Engineered Mosquitoes Prevented the Growth of Malaria-causing Parasites in Their Gut

P. Mozter,  Nature World News 2022,  2022.

Scientists have created mosquitoes that inhibit the development of malaria-causing parasites in their stomachs, therefore decreasing disease transmission to people. The genetic change allows mosquitoes to create substances in their intestines that inhibit parasite development, making parasites less likely to reach the mosquitoes’ salivary glands and be transmitted in a bite before the insects die, as per ScienceDaily. The Transmission: Zero team at Imperial College London developed the breakthrough so that it may be used with current “gene drive” technologies to distribute the alteration and substantially reduce malaria transmission. The team is planning field experiments, but first, they will rigorously verify the new modification’s safety before merging it with a gene drive for real-world testing.
