摘要: 随着基因Ⅰ型非洲猪瘟(GenotypeⅠ ASFV)在我国开始流行,使我国对ASF的诊断、预防和控制更具挑战性。本研究使用中国动物疾病预防控制中心(CADC)推荐使用的B646L引物与探针,结合针对GenotypeⅠ ASFV EP402R基因保守特异性区域设计引物与探针,建立了一种在诊断ASF的同时可对ASFV进行GenotypeⅠ ASFV鉴别的快速检测方法,并对其灵敏性、特异性进行检测。结果显示,该方法具有良好的灵敏性以及特异性,可有效用于ASFV的临床诊断以及GenotypeⅠ ASFV的监测。

Abstract: With the beginning of Genotype I African swine fever (Genotype I ASFV) epidemic in China, it makes the diagnosis, prevention and control of ASF in China more challenging. In this study, primers and probes of B646L recommended by China Animal Disease Control Center (CADC) was used, combined with primers and probes designed for the conserved specific region of GenotypeⅠ ASFV EP402R gene, to establish a rapid detection method that can identify GenotypeⅠ ASFV while diagnosing ASF, and its sensitivity and specificity were tested. The results show that the method has good sensitivity and specificity and can be effectively used for the clinical diagnosis of ASFV and the monitoring of GenotypeⅠ ASFV.

Key words: African swine fever, genotype I ASFV, real-time fluorescence quantitative PCR, EP402R, B646L
