Mean number of virus in different organs of
SARBA at day 10 post-infection. We exposed mosquitoes to an infectious blood-meal with CHIKV, DENV-2 or WNV at a titer of 108 MID50/ml. Mosquitoes were dissected to isolate organs (midgut, wings and salivary glands) for RNA extraction and virus quantification by quantitative RT-PCR. In brackets, the number of mosquitoes analyzed.
