Abstract

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
