Fig. 3: Effect of incubation period on the vector competence of North American Cx. pipiens mosquitoes for USUV.
From: North American Culex pipiens mosquitoes are competent for Usutu virus transmission
a Percentage of Cx. pipiens mosquitoes positive for USUV in the bodies, legs, and wings, and saliva at 10 (n = 31; data taken from Fig. 2), 14 (n = 22), and 21 (n = 24) DPI out of number bloodfed following exposure to a bloodmeal containing USUV Netherlands 2016. b USUV titer (log10 PFU/mosquito) in the mosquito bodies. c USUV titer in the mosquito legs and wings. d USUV titer in the mosquito saliva. Circles represent individual samples, horizontal lines represent the mean, error bars represent the standard deviation, and dashed lines represent the limit of detection (bodies: 1.4 log10 PFU/mosquito, legs and wings: 1.2 log10 PFU/mosquito, saliva: 0.4 log10 PFU/mosquito). Negative samples are graphed at half the limit of detection. ***P < 0.001, **P < 0.01, *P < 0.05.
