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 F gene was amplified by reverse transcription polymerase chain reaction (RT-PCR) from CDV-GZ1 strain. The amplified fragment was cloned and analyzed. The results showed that the length of CDV-GZ1 F gene was 1989 bp. It contained five potential N-glycosylation locations based on the derived amino acid sequences. The homology of coding amino acid between this strain and American 00-2601 and domestic HL strain was 91.6% and 91.1% respectively, it showed that they had common ancestor.
