Infection, dissemination, and transmission rates of rRVF-wt and rRVF-ΔNSm in Aedes aegypti 14 days post infection.

1Number of mosquitoes containing detectable virus by plaque assay divided by the number of mosquitoes exposed to infectious blood meal.2De = number of mosquitoes with RVFV antigen in head tissues divided by number of mosquitoes exposed to infectious blood meal.3Di = number of mosquitoes with RVFV antigen in head tissues divided by number of infected mosquitoes.4Te = number of mosquitoes with RVFV-positive saliva by plaque assay divided by number of mosquitoes exposed to infectious blood meal.5Td = number of mosquitoes with RVFV-positive saliva by plaque assay divided by number of mosquitoes with disseminated infection.6Titer expressed as log10 pfu/mL.7n = 3; titer expressed as log10 pfu/mosquito; average is the log10 geometric mean; sd = standard deviation.8rRVFV-wt n = 21; rRVFV-ΔNSm n = 7; titer expressed as log10 pfu/mosquito; average is the log10 geometric mean; sd = standard deviation.*Rate difference between virus types is statistically significant.
