FIG 2 — A successive noninfectious blood feed does not significantly impact transmission potential for DENV-4. Data are for Aedes aegypti (ORL) 14 days after infectious blood feeding with the DENV-4 Haiti (H) (red) or the DENV-4 laboratory (L) (blue) strain (1 feed) and after a subsequent noninfectious blood feed 4 days later (2 feeds). (A) Infection rates of midgut and saliva samples; (B) midgut infection intensity; (C) saliva infection intensity. Dots represent individual mosquito samples, with medians and 95% confidence intervals per group combined from three biological replicates. *, P value of <0.05 via Fisher’s exact test for infection rates and Kruskal-Wallis and Dunn’s post hoc tests (midgut) or one-way ANOVA (saliva) for infection intensity.
