Fluorescent quantitative PCR primers and probes for porcine epidemic diarrhea viruses

The invention discloses fluorescent quantitative PCR (polymerase chain reaction) primers and probes for porcine epidemic diarrhea viruses. An upstream primer and a downstream primer are shown as SEQIDNO: 1-2; a probe P1 is shown as SEQIDNO: 3; a probe P2 is shown as SEQIDNO: 4; the 3' end of sequences of the probe 1 and the probe 2 are combined with a fluorescent quenching group; and the 5' end of sequences of the probe 1 and the probe 2 are combined with different fluorescent reporter groups. The primers are relatively high in specificity and sensitivity, can detect out variant PEDV (porcine epidemic diarrhea viruses), and can detect and differentiate a variety of clinical samples so as to quickly differentiate epidemic PEDV strains; the operation is simple and practical.
