The invention discloses fluorescent quantitative RT-PCR (reverse transcriptase-polymerase chain reaction) primers, probes and a method for detecting PRRSV (porcine reproductive and respiratory syndrome virus). According to the fluorescent quantitative RT-PCR primers and probes for detecting the PRRSV, the primers comprise an AM-PRRSV primer pair and an EU-ORF1a primer pair, and the probes comprise an AM-V-PRRSV-P probe, an AM-C-PRRSV-P probe and an EU-PRRSV-P probe; and the fluorescent quantitative RT-PCR method for detecting the PRRSV comprises the steps as follows: the primers and the probes are utilized to perform multiple fluorescent quantitative RT-PCR amplification, fluorescence signals are collected after the amplification, the fluorescence signals which have amplification curves are positive, and the method is characterized in that an RT-PCR amplification system comprises the primers and the probes. The fluorescent quantitative RT-PCR primers, the probes and the method for detecting the PRRSV can detect and distinguish PRRSV American type classical strains, HP-PRRSV and European type strains simultaneously, and has the advantages of high specificity, high sensibility, high degree of automation, speediness, simplicity, convenience and the like.
