Bed Nets That Target Parasites, Not Just Mosquitoes

How next-generation bed nets could stop malaria by killing the parasites inside mosquitoes, not just the mosquitoes themselves. Transcript Bed nets have long been a cornerstone of vector control. Coated with insecticide, they serve a dual purpose: preventing bites and killing mosquitoes. But what if those nets could do more – not only kill the mosquitoes, but for those they don't kill because of increasing insecticide resistance, at least kill the parasites hidden inside them? Researchers assembled a library of antiparasitic compounds active against the form of the parasite in the mosquito midgut. They identified 81 promising compounds, some of which were already in clinical development. Of those, 22 were found to be effective against these early stages of parasite development in the mosquito and, therefore, capable of preventing onward transmission.  One class of compound stood out: ELQs, or endochin-like quinolones. These could be absorbed through the mosquito's legs in tests, therefore viable for use in a mosquito net. The researchers suggest that ELQs could offer a promising new strategy for malaria control, working alongside traditional methods to reduce malaria cases and deaths.
