ABSTRACT
A pairs of primers were designed according to the fusion protein(F)gene sequences of canine distemper virus(CDV)in GenBank.A 369 bp fragment aimed signal peptide fragment of F gene was amplified.The PCR products from viscera samples,blood,urine of fur animals including foxes,minks and raccoon dogs,which collected in the years 2005-2007,were cloned to pMD18-T Vector and sequenced.We obtained 13 positive signal peptide fragments from wild-type strains.The results indicated there was obviously genetic diversity between the wild-type strains and CDV3 and other vaccine strains.The homology with CDV3 is 80.7%-83.2%in nucleotide,and 64.8%-71.3%in amino acid.The analysis for the hydrophobic regions indicated the function of signal peptide fragment may be changed.This study can offer aca- demic data to research of CDV genetic variation and epidemiology.
