Detection of dengue virus type 2 in Aedes albopictus by nucleic acid hybridization with strand-specific RNA probes.

摘要

A molecular hybridization technique with radiolabeled, strand-specific RNA probes was developed to detect dengue virus type 2 RNA in pools of infected Aedes albopictus mosquitoes. One infected mosquito in a pool of 25 could be detected, corresponding to a dengue virus type 2 titer of 2.75 log10 50% tissue culture infectious doses.
