Abstract: Two pairs of primers were designed and synthesized based on the sequence of the Onderstepoort strain of canine distemper virus reported in GenBank,and the N gene was amplified by reverse transcription polymerase chain reaction(RT-PCR) from CDV-GZ1 strain in Guizhou.The amplified fragment was cloned and analyzed.The results showed that the length of N gene was 1572 bp.The homology of coding amino acid between this strain and CDV Shuskiy and 01-2689 strain was 98.9% and 97.1% respectively,while above 95% among other domestic strain.It illustrated that N protein have highly conservation property.
