BACKGROUND: Zika virus (ZIKV) has been isolated from many mosquito species in nature, but it is believed that the main vectors in urban environments are species of the genus Aedes. Here, we detected and isolated ZIKV in samples from Aedes aegypti, Aedes taeniorhynchus and Culex quinquefasciatus, collected during the Zika epidemic in Vitória, southeast Brazil. Using quantitative real-time polymerase chain reaction, ZIKV detection was performed in mosquito samples collected from February to April 2016. RESULTS: Overall, six pools of mosquitoes were positive for ZIKV: four of Cx. quinquefasciatus, one of Ae. aegypti and one of Ae. taeniorhynchus. Their genomes were sequenced. CONCLUSIONS: These results support and strengthen the hypothesis that other mosquito species can also be involved in ZIKV transmission.
