[Study of the possibilities of contamination and transmission by the mosquitoes Culex pipiens f. molestus Fors, a pathogen of West Nile fever].

Experimental studies have demonstrated that the mosquitoes Cx. p. f. molestus fed with virus-containing suspensions, by using an artificial membrane and hygroscopic surface, are infected in 60 to 100% cases and transmit the accepted pathogen of West Nile fever (WNF) to newborn albino mice on blood sucking. The mosquitoes of this species maybe involved in the spread of the pathogen of WNF during its epidemic outbreaks.
