| Abstract: | In this study,LNA-TaqMan probe-based real-time PCR was established using specific primers and probes according to the P72 gene of African swine fever virus(ASFV).The results showed that the LNA-TaqMan probe-based real-time PCR had higher sensitivity,and the minimum detection limit was 3.9 copies/μL.The LNA-TaqMan probe-based real-time PCR was no cross-reaction with various pathogens such as swine fever virus,porcine reproductive and respiratory syndrome virus,and porcine circovirus type 2.The intra-and inter-assay coefficient of variation was less than 1%,with good repeatability.The results of 56 clinical samples were consistent with the results of qPCR recommended by OIE,and the coincidence rate was 100%.The LNA-TaqMan probe-based real-time PCR established in this study had ideal sensitivity,specificity,and repeatability,which provides a new technology choice for the detection of ASFV. |
