Incrimination of shrews as a reservoir for Powassan virus
Abstract
Goethert and colleagues use a host-specific retrotransposon targeted real time PCR assay on questing nymphal ticks to identify a reservoir for Powassan virus lineage 2 (or deer tick virus). Infected ticks were found to have preferentially fed on shrews, as opposed to white-footed mice as was expected, suggesting that they may be a reservoir host for this virus.
