Fig. 2From: Experimental studies on comparison of the vector competence of four Italian Culex pipiens populations for West Nile virusWNV replication in Cx. pipiens population collected from Frascati. Comparison of WNV mean titre in infected females of Cx. pipiens from Frascati calculated both by qRT-PCR (a) and by titration on VERO cells (b). Cx. pipiens females were exposed to an infectious blood-meal containing 7.97 PFU/mL of WNV; samples of 5-10 fed females were collected at different days post infection and individually analysed for the presence of WNV in body, legs plus wings and in salivaBack to article page
