Infection, dissemination, and transmission rates of rRVF-wt and rRVF-ΔNSm in <i>Aedes aegypti</i> 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.
