Zika virus (ZIKV) is widely distributed in Brazil and the Northeast Region (NE) is the most affected zone, showing the highest incidence of microcephaly associated with ZIKV congenital infections worldwide. We report attempts to infect three populations of Culex quinquefasciatus from severely affected sites in the NE and Southeast Region (SE) of Brazil with three strains of ZIKV isolated from these localities. An Aedes aegypti population from the SE was used as a positive control. All tested Cx. quinquefasciatus populations were refractory to the ZIKV isolates. For these reasons, we believe Cx. quinquefasciatus should not be considered a potential vector of ZIKV in Brazil.
寨卡病毒(ZIKV)在巴西广泛传播,东北地区(NE)是受影响最严重的区域,在全球范围内,该地区与寨卡病毒先天性感染相关的小头畸形发病率最高。我们报告了用从巴西东北部和东南部地区(SE)受严重影响地点分离出的三株寨卡病毒感染来自这些地区的三群致倦库蚊的尝试。来自东南部的一群埃及伊蚊用作阳性对照。所有测试的致倦库蚊种群对寨卡病毒分离株均具有抗性。基于这些原因,我们认为致倦库蚊不应被视为巴西寨卡病毒的潜在传播媒介。
