Fig. 4: Effect of USUV dose on the vector competence of North American Cx. pipiens mosquitoes using an artificial bloodmeal.
From: North American Culex pipiens mosquitoes are competent for Usutu virus transmission
a Percentage of Cx. pipiens mosquitoes positive for USUV in the bodies at 10 DPI out of number bloodfed following exposure to a bloodmeal containing USUV Netherlands 2016 at various doses (log10 PFU/mL). Data for the 7.9 log10 PFU/mL group is taken from Fig. 2. Infection rate: (# of positive mosquito bodies/total number tested) * 100. b USUV titer (log10 PFU/mosquito) in the mosquito bodies at each dose. c USUV titer in the mosquito legs and wings at each dose. d USUV titer in the mosquito saliva at each dose. Circles represent individual samples, horizontal lines represent the mean, error bars represent the standard deviation, and dashed lines represent the limit of detection (bodies: 0.4 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.
