To supplement the results of thermal resistance of bovine Parvovirus (Haden strain, BPV) published at an earlier time, we carried out assays at 60° C (moist heat) aimed at comparing the thermal resistance of BPV with that of the hepatitis B virus (HBV). What we know about the resistance of HBV at a temperature of 60°C is mainly based on data collected within the context of blood product pasteurization. The results suggest that at a temperature of 60°C, BPV shows at least the same thermal resistance as HBV. Thus, BPV - which is easier to handle - can be considered a good test virus when it comes to verifying the HBV efficacy of thermal disinfection techniques. BPV is unusually resistant against a dry heat of 100°C, with the inactivation value largely depending upon the residual moisture of the lyophilisate. As a result of reducing the residual moisture from 2% to less than 1%, the exposure time has to be prolonged by ca. 2.5 times to achieve the same virucidal effect.
