Zika virus is a newly emergent mosquito-borne flavivirus that has caused recent large outbreaks in the new world, leading to dramatic increases in serious disease pathology including Guillain-Barre syndrome, newborn microcephaly, and infant brain damage. Although mosquitoes are thought to be the primary mosquito species driving infection, the virus has been isolated from dozens of mosquito species, including and species, and we lack a thorough understanding of which mosquito species to target for vector control. We exposed , , and mosquitoes to blood meals supplemented with two Zika virus strains. Mosquito bodies, legs, and saliva were collected five, seven, and 14 days post blood meal and tested for infectious virus by plaque assay. Regardless of titer, virus strain, or timepoint, , , and mosquitoes were refractory to Zika virus infection. We conclude that , , and mosquitoes likely do not contribute significantly to Zika virus transmission to humans. However, future studies should continue to explore the potential for other novel potential vectors to transmit the virus.
寨卡病毒是一种新出现的经蚊子传播的黄病毒,最近在新大陆引发了大规模疫情,导致包括吉兰-巴雷综合征、新生儿小头畸形和婴儿脑损伤在内的严重疾病病理情况急剧增加。尽管蚊子被认为是传播感染的主要蚊种,但该病毒已从包括[具体蚊种1]和[具体蚊种2]在内的数十种蚊子中分离出来,而且我们对哪些蚊种是病媒控制的目标缺乏全面了解。我们让[具体蚊种3]、[具体蚊种4]和[具体蚊种5]蚊子吸食添加了两种寨卡病毒毒株的血餐。在血餐后第5天、第7天和第14天收集蚊子的身体、腿部和唾液,通过蚀斑测定法检测其中的传染性病毒。无论病毒滴度、毒株或时间点如何,[具体蚊种3]、[具体蚊种4]和[具体蚊种5]蚊子对寨卡病毒感染均具有抗性。我们得出结论,[具体蚊种3]、[具体蚊种4]和[具体蚊种5]蚊子可能对寨卡病毒向人类的传播贡献不大。然而,未来的研究应继续探索其他新型潜在病媒传播该病毒的可能性。
