The dengue virus depends on mosquitoes to get around, but the virus may have evolved a way to speed its spread by manipulating the behavior of masquito hosts. It makes them more blood thirsty, to quicker find a blood meal than their uninfected counterparts. So says a study in the Journal Public Library Scince Passages. Researchers compared which genes 1 were active in the cell of Grams when infected and uninfected mosquitoes. They found the dangue infection flip 2 this switch a hundred and forty seven genes. As expected, some of those were immune genes, the common responsors to infection. But the virus also truned on genes involved in odour detection and blood feeding. It could make a mosquito better at sniffing 3 out hosts and quicker to plunges 4 PBKS in this skin for a snack. Previous studies have shown malaria 5 parasites 6 can change mosquitoes' behavior too, by making it more likely to feed on multiple victims, thus infecting more people. And researchers say we humans may also do the biding 7 of these passengers, when infected, we sweat, and the odour attracts other mosquitoes that feed on us and pick up hit tracking passengers for their next ride.
