Key result
Novel real-time fluorescence PCR assay increases PCV3 detection by ~40% versus previous methods.
Why the study?
Porcine circovirus type 3 (PCV3) is an emerging virus worldwide, necessitating development of sensitive and specific molecular detection assays.
Does a newly developed real-time fluorescence PCR assay improve the detection rate of PCV3 compared to previously reported methods in clinical samples?
Does a newly developed real-time fluorescence PCR assay improve the detection rate of PCV3 compared to previously reported methods in clinical samples?
Absolute Event Rate: 28% vs 20%
A newly developed real-time fluorescence PCR assay offers high sensitivity and specificity for detecting porcine circovirus type 3, outperforming previous methods in clinical samples.
May aid PCV3 surveillance in swine; leaves open translation to routine diagnostics without further validation.
BACKGROUND: Porcine circovirus type 3 (PCV3) has been an emerging porcine virus spread around the world. The conserved DNA sequence of PCV3 enabled good performance in molecular biological assays. RESULT: In this study, we developed a real-time fluorescence PCR assay for the detection of PCV3. The conserved region within Capsid genome of PCV3 was selected for the design of primer pairs and probes. After optimizing, a primer pair and probe was screened, providing high sensitivity (10 copies/μL) and specificity (no cross reaction with other porcine viruses or common bacterium). In addition, this method was applied in the detection of 110 clinical samples, and the performance was compared with other previously reported PCR and real-time PCR methods. This method provided higher detection rate. CONCLUSION: A real-time fluorescence PCR assay has been developed for the detection of PCV3, with high sensitivity and specificity, exhibiting good performance in detecting clinical samples.

Yuan et al. (2020) studied Porcine circovirus type 3 (PCV3) infection (n=110). Real-time fluorescence PCR assay vs. Common PCR and previously reported real-time PCR methods was evaluated on Detection of PCV3 in clinical samples. The newly developed real-time fluorescence PCR assay for PCV3 demonstrated high sensitivity (10 copies/μL), high specificity, and a higher detection rate in clinical samples compared to previously reported PCR methods.
