The aim of this study was to develop a droplet digital polymerase chain reaction (ddPCR) method to detect African swine fever virus (ASFV). The methods of ASFV real-time PCR and ddPCR were established and optimal reaction conditions were confirmed. Each method was evaluated for linearity, limit of detection, and specificity. The results indicated that ASFV ddPCR had a high degree of linearity ( ≥ 0.998) and specificity. The detection limit was 10 copies/reaction, which was approximately a 10-fold greater sensitivity than real-time PCR. This sensitive method could be used as an efficient molecular biology tool to diagnose ASFV, which is very important for preventing the spread of diseases across borders.
本研究的目的是开发一种用于检测非洲猪瘟病毒（ASFV）的液滴数字聚合酶链反应（ddPCR）方法。建立了ASFV实时PCR和ddPCR方法，并确定了最佳反应条件。对每种方法的线性、检测限和特异性进行了评估。结果表明，ASFV ddPCR具有高度的线性（≥0.998）和特异性。检测限为10拷贝/反应，其灵敏度比实时PCR高约10倍。这种灵敏的方法可作为诊断ASFV的有效分子生物学工具，这对于防止疾病跨境传播非常重要。
