摘要：[Objective] In this study, the quantitive detection of PCV2 （porcine circovirus type 2） in vitro was achieved. We aimed to establish two kinds of TaqMan real-time PCR methods based on PCV20RF1 and ORF2 respectively and compare them. [Method] According to the relatively＇conserved sequences of PCV20RF1 and ORF2 registered in GenBank, two pairs of specific primers and TaqMan probes were designed and synthesized. Then the recombinant plasmids containing the whole sequences of PCV20RF1 and ORF2 were constructed to draw the standard curves through optimizing the reaction system and conditions. And thus two kinds of TaqMan real-time PCR detection methods based on the whole sequences of ORF1 and ORF2 respectively were constructed for PCV2. [Result] For the two established standard curves, the Ct values showed a good linear relationship with the loga- rithms of copy numbers of templates （F2〉0.99）. The amplification efficiency ranged from 90% to 110%. The amplifications all had a good repeatability with variation coefficients within groups all less than 5%. Moreover, the amplifications all had a good specificity. When the sequences of porcine parvovirus （PPV）, porcine circovirus type 1 （PCV1）, swine pseudorabies virus （PRV）, porcine reproductive and respiratory syndrome virus （PRRSV） were used as templates, the target sequence was not amplified. The amplifications also had a high sensitivity. The ORF1 detection method could reach 1.0x10T copies/;ul, and the ORF2 detection method could reach 1.0×10^2 copies/μl. The two established real-time PCR detection methods were used to detect the 80 clinical samples respectively. The results showed the magnitudes of 72 amplified samples were basically consistent between the 2 detection methods, while the magnitudes of the other 8 amplified samples were inconsistent. Then the 8 samples were detected with SYBR Green I real-time PCR method established based on the sequence of PCV2-1ike factor P1 by Wen et aL The PCV2-1ike factor P1 was ampl
