Abstract: The studies showed that Yunnan strain of Aedes albopictus could be infected and multiply dengue (DEN) and Japanese encephalitis (JE) viruses in their bodies by ingesting blood-virus meal,or biting viremic chickens.Infected female mosquitoes were capable of transmitting DEN and JE virusesto suckling mice and chickens by biting and blood-sucking.Their transmission rates to suckling mice were22.22% for DENI, 37.50% for DEN2, 25.00% for DEN3, 44.44% for DEN4 and 37.50% for JE onthe 10th day after infection, and transmission rates to chickens were 100% for DEN4 and 66.67% forJE on the 10th day after infection.These results indicate that Ae.albopictus mosquitoes have the potential to play a role in the maintenance and transmission of DEN and JE viruses in nature.
摘要: 云南株白纹伊蚊通过吸食含病毒的血餐或叮吸有病毒血症的小鸡血,能感染登革和乙型脑炎病毒,并能在蚊体内增殖。感染蚊经叮咬吸血,能将这两种病毒传播给乳鼠或小鸡。雌蚊感染后第10天,对乳鼠的传播率登革1、2、3、4型和乙型脑炎依次为22.22%、37.50%、25.00%、44.44%和37.50%;对小鸡的传播率登革4型和乙型脑炎分别为100%和66.67%。实验结果表明,白纹伊蚊在登革和乙型脑炎病毒保存和传播中起重要作用。
