Results showed that strains F48E9 and Xiny were inadequately virulent to cause piglet illness or death. However, the virus agents are detectable in the pig body. F48E9 can cause the death of SPF chickens but Xiny caused no pathology in such chickens. Keywords: Newcastle disease virus;pig;SPF chicken;pathogenicity;interspecies transmission
