Abstract: Two sets of specific primers were designed according to the sequences of Newcastle diseases virus (NDV) and duck plague virus (DPV) in GenBank. It was shown that all samples containg NDV and DPV could be amplified into two specific bands, 419 bp for NDV and 602 bp for DPV by this duplex PCR, but no specific band was amplified from other avian pathogenic virus and bacteria. As little as 0.4 pg of NDV RNA and 126 pg of DPV DNA could be detected by this duplex PCR.

Key words: Newcastle diseases virus; duck plague virus; duplex PCR
