USUV titers in bodies and saliva of Cx. pipiens after oral exposure to infectious chicken or human blood. a, b Cx. pipiens pipiens and c, d Cx. pipiens molestus were incubated at 28 °C, and virus titers were determined 14 days post-infection. Data points represent individual mosquitoes exposed to USUV. Lines among the dots indicate the mean viral titers. Error bars show the standard error of the mean (SEM). A non-significant difference is indicated by ns (p > 0.05; Mann–Whitney U test)
