Zika Virus in Salivary Glands of Five Different Species of Wild-Caught Mosquitoes from Mexico

Zika virus (ZIKV) is a mosquito-borne pathogen, and Aedes aegypti has been identified as the main vector of the disease. Other mosquito species in the Aedes and Culex genera have been suggested to have the potential for being competent vectors based on experimental exposition of mosquitoes to an infectious blood meal containing ZIKV. Here, we report the isolation in cell culture of ZIKV obtained from different body parts of wild-caught female mosquitoes ( Ae . aegypti , Ae . vexans , Cx . quinquefasciatus , Cx . coronator , and Cx . tarsalis ) and whole male mosquitoes ( Ae . aegypti and Cx . quinquefasciatus ) in Mexico. Importantly, this is the first report that shows the presence of the virus in the salivary glands of the wild-caught female mosquitoes species, Cx . coronator , Cx . tarsalis , and Ae . vexans . Our findings strongly suggest that all the species reported herein are potential vectors for ZIKV.
