Tembusu virus (TMUV; Ntaya serocomplex) was detected in two pools of mosquitoes captured near Sangkhlaburi, Thailand, as well as from sera from sentinel ducks from the same area. Although TMUV has been isolated from several mosquito species in Asia, no studies have ever shown competent vectors for this virus. Therefore, we allowed mosquitoes captured near Sangkhlaburi to feed on young chickens that had been infected with TMUV. These mosquitoes were tested approximately 2 weeks later to determine infection, dissemination, and transmission rates. developed high viral titers after feeding on TMUV-infected chicks and readily transmitted virus to naïve chickens. In contrast, seemed less susceptible to infection, and more importantly, zero of five with a disseminated infection transmitted virus by bite, indicating a salivary gland barrier. These results provide evidence for the involvement of mosquitoes in the transmission of TMUV in the environment.
