RESUMO
Carnivore protoparvovirus 1 (CPPV-1) is widespread among free-living carnivores, and CPPV-1 infection may directly or indirectly impact on the population of endangered carnivore species. In this study, we used molecular screening of viral capsid protein 2 (VP2) from 2015 to 2017, to assess the prevalence of CPPV-1 infection in 9 live-trapped (LT) and 17 vehicle collision (VC)-affected free-living leopard cats (Prionailurus bengalensis chinensis). In addition, we conducted the phylogenetic analysis to evaluate the possible transmission of CPPV-1 between domestic carnivores and leopard cats. We identified the circulation of feline parvovirus and variants of canine parvovirus (CPV), including CPV-2a, CPV-2b, and CPV-2c, in the free-living leopard cat population. The partial sequences of different variants of VP2 obtained from the leopard cats were identical with those obtained from the domestic dogs and cats in Taiwan. Our result suggested that CPPV-1 was currently transmitted between domestic carnivores and leopard cats in Taiwan. A plan of conservation measures based on vaccination program for domestic carnivores, strict controls on populations of free-living dogs and cats and limiting road development only to low-risk areas for leopard cats should be encouraged.
