Fig. 3From: Infection, dissemination, and transmission efficiencies of Zika virus in Aedes aegypti after serial passage in mosquito or mammalian cell lines or alternating passage in both cell typesSalivary gland infection and transmission rates of Ae. aegytpi infected with host cell-adapted Zika virus. Salivary glands infection rates of Ae. aegytpi challenged with host cell-adapted Zika virus at a 14 days and b 21 days after infectious blood meal (Kruskal-Wallis test, X2 = 1.129, df = 3, P ≥ 0.05 and X2 = 1.858, df = 2, P ≥ 0.05, respectively). Transmission rates of Ae. aegypti challenged with host cell-adapted Zika virus at c 14 days and d 21 days after infectious blood meal (Mann-Whitney U-test, Z = 1.449, P ≥ 0.05 and Z = − 0.062, P ≥ 0.05, respectively).
