By using primers based on the sequence of the VP2 gene of canine parvovirus (CPV), we established a rapid and specific assay for identification of the virus from fecal specimens based on the polymerase chain reaction (PCR). By use of a pair of primers, a specific 226-bp sequence was amplified by the PCR. All strains of CPV tested gave a specific amplification product by the PCR, while neither porcine parvovirus nor host cell did so. The PCR assay can detect fewer particles of CPV than the conventional methods, being able to detect CPV from fecal specimens in a rapid manner, provided that gel filtration of the samples through a spun column was done to remove inhibitory substances from the fecal specimens. These results suggest that the PCR assay can detect the presence of CPV in dogs early enough to prevent secondary infection by CPV in veterinary hospitals.
