| Abstract | Summary The development and transmission of yellow fever virus in Aedes aegypti mosquito were studied after feeding or intrathoracic inoculation. Five different viral strains were examined: two vaccinal strains, one strain isolated from man in South America, two African wild strains isolated respectively from ticks and mosquitoes. Depending on the examined wild strains, the results show great differences in the time of latency in the mosquito before it transmits the virus to the suckling mouse. It appears that the virus strains isolated in South America have a much longer time of latency than the African ones. Vaccinal strains do not develop in the mosquito fed on infected suckling mouse (table I, column 3). On the other hand, the mosquito is infected when intrathoracically inoculated. In that case transmission to suckling mouse is possible. These experiments reveal the part of the intestinal barrier in the infection of A. aegypti mosquitoes, when fed with vaccinal strains. A comparative study of these five viral strains was made in vitro in A. aegypti-cloned cells but with no greatly different specific results. |
