Dengue fever is one of the fastest-growing mosquito-borne diseases in the world, causing illness and economic challenges in many countries. Current mosquito control methods, such as insecticides, are often costly, less effective over time, and harmful to the environment. An alternative approach uses naturally occurring bacteria called Wolbachia, which live inside insects. When certain Wolbachia strains are introduced into mosquitoes, they can reduce the insects’ ability to spread viruses like dengue. In our study, we compared the genetic makeup of several Wolbachia strains to identify new candidates that may work better for controlling dengue. We discovered that a strain called wCin2USA1 has strong potential because it shares important features with two strains already used successfully, while also having unique advantages. These include genes that help prevent mosquitoes from reproducing normally when carrying different Wolbachia strains, which can reduce mosquito populations. Our findings suggest that wCin2USA1 could be developed as a new, environmentally friendly tool to help reduce dengue transmission.
