Abstract

The authors previously characterized a partial nucleic acid sequence for a novel virus, Phasi Charoen virus (PhaV), which was isolated from Aedes aegypti larvae in Thailand, and PhaV appears to belong to the family Bunyaviridae based on phylogenetic analysis of amino acid sequences. In this study, we examined whether adult female mosquitoes in Thailand are infected by PhaV, and they found that over 20% of adult female mosquitoes were infected by PhaV. These viruses were genetically similar to strains. This result suggested a high prevalence of PhaV in adult female mosquitoes.

 

Key words: PhaV, bunyavirus, female mosquito, high prevalence.
