Abstract
In this study, we describe a novel and rapid method for the construction of a full-length infectious clone (pPPV). The constructed clone contained an engineered EcoRv site that served as a genetic marker and was shown to be infectious when transfected into a monolayer of PK-15 cells. The rescued virus (rPPV) of the infectious clone was found to be indistinguishable from wild-type virus BQ in terms of its biological properties. The generation of this PPV infectious clone provides a potentially powerful tool with which to elucidate the molecular pathogenesis of PPV.
