Interest is high in mosquito microbes and viral pathogens due to their effects on human health. A bacteria called Wolbachia, can infect insects including mosquitoes with unpredictable and interesting results. It has been shown that infection of mosquitoes with Wolbachia can inhibit Dengue virus in mosquitoes.
Brazilian scientists* have found as strain of Wolbachia that can reduce or block transmission of Zika virus. These laboratory results will require further testing. Infecting mosquito populations with Wolbachia is not necessarily straightforward. With additional field testing and research, Wolbachia may be an additional tool in the battle against Zika.
