Abstract
A new amdoparvovirus, named raccoon dog and fox amdoparvovirus (RFAV), was identified in farmed sick raccoon dogs and arctic foxes. Phylogenetic analyses showed that RFAV belongs to a new species within the genus Amdoparvovirus of the family Parvoviridae. An RFAV strain was isolated in Crandell feline kidney cell culture.
Highlights
A new amdoparvovirus, named raccoon dog and fox amdoparvovirus (RFAV), was identified in farmed sick raccoon dogs and arctic foxes
The Study During July–December 2012 and 2013, sick raccoon dogs and arctic foxes, which were farmed for fur products on 6 farms in Jilin and Liaoning provinces, China, were received for quarantine inspection at the Fur Animal Disease Laboratory, Institute of Special Animal and Plant Sciences, Chinese Academy of Author affiliations: State Key Laboratory for Molecular Biology of Special Economical Animals, Institute of Special Animal and Plant Sciences, Chinese Academy of Agricultural Sciences, Changchun, China
Because signs in the sick animals sent for quarantine inspection were similar to those in Aleutian mink disease, we first used Aleutian mink disease virus (AMDV)-specific counter-immunoelectrophoresis (CIEP) (5) to test serum samples of six 3-month-old sick raccoon dogs from farm A
Summary
Because signs in the sick animals sent for quarantine inspection were similar to those in Aleutian mink disease, we first used AMDV-specific counter-immunoelectrophoresis (CIEP) (5) to test serum samples of six 3-month-old sick raccoon dogs from farm A. DNA extracted from blood of two 3–7-month-old sick raccoon dogs from farm C was RFAV DNA PCR positive, and serum samples from these animals were CIEP positive. Two 7-month-old raccoon dogs from farm D appeared healthy but on necropsy showed cyanosed splenomegaly Their blood and spleens were RFAV DNA positive, and serum was CIEP positive. Of the 29 sick raccoon dogs, two 3–7-month-old animals were both canine parvovirus 2 and RFAV DNA positive by PCR in blood or spleen samples. One kidney sample from a 3-monthold fox of 3 tested on farm F showed renal enlargement and was RFAV DNA PCR positive.
