摘要: A combined reverse-transcription polymerase chain reaction (RT-PCR) method was developed for the detection and differentiation of wild-type vaccine strains canine distemper virus (CDV). pair primers (P1/P2) used to detect both CDV vaccines. Another (P3/P4) only strains. 335bp fragment amplified from genomic RNA 555bp specifically No amplification achieved uninfected cells, cells infected with parvovirus, coronavirus, or adenovirus. The RT-PCR detected effectively differentiated by two separate RT-PCRs. can be clinical epidemiological surveillance. phylogenetic analysis hemagglutinin gene local revealed that seven isolates all belonged Asia-1 lineage, were clustered closely one another at same location. These results suggested genotype is circulating currently in domestic dogs China.
