Development of RT-PCR for detecting virulent strains of waterfowl-origin avian paramyxovirus type 1

An RT-PCR method was developed to detect virulent strains of waterfowl-origin avian paramyxovirus type 1(vwAPMV-1).The primers were designed according to the sequences of the fusion protein gene of vwAPMV-1s available at the GenBank.The result showed that the 400 bp of specific fragments were amplified in vwAPMV-1.However,negative results were obtained from Pasteurella multocide,EDS,DEV,IBDV,H9N2 influenza virus,DHV-1 and low virulent strains of waterfowl-origin avian paramyxovirus type 1.And,the 10pg of vwAPMV-1 RNA was amplified by the sensitivity test for the RT-PCR.The results indicated that the RT-PCR could be used for vwAPMV-1 detection.
