摘要: 骆驼痘( Camelpox,CML)是一种广泛流行的骆驼病毒性传染病,它主要发生于中 东和东北非的大规模骆驼群,给骆驼产业造成了巨大的经济损失。该研究通过对GenBank中 所公布的13个骆驼痘病毒分离株全基因组核苷酸序列进行同源性比较,选取其ATIP基因保守 序列,筛选出了一套特异性引物和探针,建立了相应的实时荧光PCR检测方法。结果表明,该 方法特异性强、重复性好、灵敏度高,其最低检测限度为7.8 copies/μL。

Abstract: Camelpox(CML)is a widespread infectious viral disease of camels that occurs mostly in the Middle East and in North East Africa on a substantial scale and causes huge economic losses to the camel industry. In the present study,the homology comparison of the complete genome nucleotide sequences of 13 camelpox virus isolates published in GenBank were performed,then a set of specific primers and a specific probe based on their conserved sequences of the ATIP gene were designed and a real⁃time fluorescent polymerase chain reaction(PCR)assay was developed. The results showed that this method had high specificity,good repeatability,high sensitivity,and its minimum detectable limit was 7.8 copies/μL.
