May improve PCV3 detection in swine; leaves open routine diagnostic adoption pending validation.
Porcine circovirus 3 (PCV-3) is a newly emerging virus that poses a potential threat to the swine industry. We developed a sensitive assay utilizing droplet digital PCR (ddPCR) to detect PCV-3. Specificity of the assay was confirmed by the failure of amplification of DNA of other relevant viruses. The detection limit for ddPCR was 1 copy/μL, 10 times greater sensitivity than TaqMan real-time PCR (rtPCR). Both methods showed a high degree of linearity, although TaqMan rtPCR showed less sensitivity than ddPCR for clinical detection. Our findings indicate that ddPCR might offer faster and improved analytical sensitivity for PCV-3 detection.
