Fig. 2.

Transmission rate estimated for Culex quinquefasciatus mosquitoes injected with WNV, based on sample type at 7 dpi (dark-gray bars; N = 38) and 10 dpi (light-gray bars; N = 33^†). ^†SG were only dissected from 15 out of the 33 mosquitoes at 10 dpi and that only 6 mice were successfully exposed to WNV. Error bars represent the 95% binomial confidence intervals. Asterisks (*) indicate significant comparisons at 10 dpi based on a Fisher exact [23] test after Holm correction for multiple testing [24]. Abbreviations: dpi, Days post-infection
