摘要: 犬瘟热是由犬瘟热病毒引起的犬科烈性传染病,给患病动物带来重大危害。本研究基于犬瘟热病毒的NP蛋白基因设计特异性引物,利用RT-PCR获得287 bp目的片段,经TA克隆并测序。结果表明,该片段与NCBI上公布的犬瘟热病毒NP序列(登录号:EU716322)同源性达到98%。利用该特异性的RT-PCR方法,检测杭州市及周边部分地区犬瘟热的流行情况,结果表明,整个杭州及周边地区犬瘟热病毒总阳性检出率为6.7%,杭州城区阳性个体数最多,阳性率最高达到18.8%,其他地方(临安、台州、舟山)阳性率较低。该研究为犬瘟热的综合防制提供基础数据。

Abstract: Canine distemper caused by canine distemper virus (CDV) is acute infection disease of canine, which caused severe losses. In this study, specific primers recognized CDV nucleoprotein were designed, the 287 bp production was amplified by RT-PCR. This production was cloned by TA cloning and sequenced, the results showed that there was a high homogeneity of 98% in nucleotide with canine distemper virus NP sequence (accession number: EU716322) published in the GenBank. Epidemic of canine distemper in Hangzhou and other cities nearby was investigated by this specific RT-PCR. The results showed that total positive detection rate of CDV was 6.7%, the number of positive individuals in Hangzhou city was largest and positive detection rate was most up to 18.8%, positive detection of other cities (Linan, Taizhou, Zhoushan) were lower. The study is basic to prevention and treatment of canine distemper.
