Key result
Real-time PCR detects duck circovirus at a ~10-fold lower limit than conventional PCR.
Why the study?
Development of diagnostic tests for duck circovirus infections was needed to improve detection and quantification of viral DNA in affected ducks.
Population
101 bursa of Fabricius samples from dead or sick ducks aged 1 to 12 weeks from 37 flocks
Comparison
Conventional PCR test vs SYBR Green-based real-time PCR test for DuCV detection
Design
Observational study developing and comparing PCR diagnostic methods

May enhance duck circovirus surveillance in research; leaves open field validation before diagnostic adoption.
Observational (n=101)
Real-time PCR provides a more sensitive method for detecting and quantifying duck circovirus compared to conventional PCR.
Fringuelli et al. (2005) conducted an observational in Duck circovirus (DuCV) infection (n=101). Real-time PCR test vs. Conventional PCR test was evaluated on Detection limit and detection rate of DuCV DNA. A newly developed real-time PCR test for duck circovirus showed a 10-fold lower detection limit than conventional PCR in the presence of cellular DNA and detected more positive samples.
