Porcine parvovirus (PPV) is a major causative agent of reproductive failure in swine, which currently affects the swine industry worldwide. Although PPV was identified several years ago, little is known about how it overcomes host innate immunity. In this study, we used quantitative real-time PCR and a luciferase reporter assay to determine whether PPV infection induces type I interferon (IFN-¦Á and IFN-¦Â) and whether PPV infection blocks dsRNA-induced IFN-¦Â promoter activation in cell cultures. The results indicate that PPV does not induce type I interferon and that the NS2 protein of PPV could blocks dsRNA-induced IFN-¦Â promoter activation.
