摘要: 为查明4份疑为患细小病毒病军犬的病原及其特性,为进一步的免疫研究奠定基础,本试验将4份送检的犬肠道内容物过滤后分别接种猫肾细胞(F81),培养5 d后,未出现细胞病变的带毒盲传。同时提取病料的总DNA,用犬细小病毒的VP2特异性引物进行PCR扩增,PCR阳性产物克隆至pMD18-T载体测序,并与已知参考毒株序列进行比对及系统发育分析。测序结果表明,用F81细胞分离到4株细小病毒;经VP2基因比对分型结果表明,4株细小病毒毒株均属CPV-2a,分别命名为CPV-JQ、CPV-CM、CPV-M和CPV-KM。

Abstract: To ascertain the pathogen and characteristics of 4 strains canine parvovirus, and establish foundation for further immunization research,the intestinal tract content of 4 different pathogenic dogs were inoculated into the feline kidney F81 cells after aseptic processing. We extracted the total DNA and amplified the VP2 gene with specific primers, then sequenced and typed with typical canine parvovirus’strains. 4 strains of CPV were isolated with F81 cells and the results of typing the VP2 genes showed that 4 canine parvovirus strains all belonged to CPV-2a, respectively named CPV-JQ, CPV-CM, CPV-M and CPV-KM.
