Alternative transmission routes have been described for Zika virus (ZIKV). Here, we assessed for the first time the venereal transmission of ZIKV between Aedes aegypti under laboratory conditions.
Orally-infected mosquito females were able to transmit the virus to males venereally, and males inoculated intrathoracically were capable of infecting females during mating. The genome of venereally-transmitted virus recovered from males was identical to that of ZIKV ingested by mated females.
We conclude that venereal transmission between Aedes mosquitoes might contribute to Zika virus maintenance in nature.
寨卡病毒(ZIKV)存在多种可能的传播途径。本研究首次在实验室条件下评估了埃及伊蚊(Aedes aegypti)之间的性传播。
经口感染的雌性蚊子能够通过性途径将病毒传播给雄性蚊子,而经胸部接种的雄性蚊子在交配时能够感染雌性蚊子。从雄性蚊子中恢复的性传播病毒的基因组与交配雌性蚊子摄入的 ZIKV 相同。
我们的结论是,埃及伊蚊之间的性传播可能有助于寨卡病毒在自然界中的维持。
