Resumo: O'nyong-nyong virus (ONNV) - chikungunya virus (CHIKV) are closely related alphaviruses that cause human disease in Africa - Asia. Like most alphaviruses, CHIKV is vectored by culicine mosquitoes. ONNV is considered unusual as it primarily infects anopheline mosquitoes; however, there are relatively few experimental data to support this. In this study, three strains of ONNV - one strain of CHIKV were evaluated in Anopheles gambiae - Aedes aegypti mosquitoes - in four cell lines. As predicted, CHIKV was not infectious to An. gambiae, - we observed strain-variability for ONNV with respect to the ability of the virus to infect An. gambiae - Ae. aegypti. The species specificity in vivo was reflected by in vitro experiments using culicine - anopheline-derived cell lines.
