Y4 fragment was cloned into a PMD18-T vector and the nucleotide sequence determined. Partial sequencing of the CPV-VP2-Y3? Y4 DNA fragment showed 99% nucleotide homology with that of the canine parvovirus,strain CPV/HN-1.

• 将分离到的犬细小病毒VP2 Y34基因片段克隆到PMD1 8 T载体 ,其病毒基因组CPV VP2 Y34序列测定结果显示与作者在GENEBANK发表的肺病变犬细小病毒CPV HN 1株有 99%25同源性
