Detection and Differentiation of Vaccine and Wild-type Strains of PPRV by Duplex Real-time RT-PCR
摘要
Abstract
To differentiate vaccine virus and wild-type peste des petits ruminants virus(PPRV)by duplex real-time RT-PCR,one pair of primers and two TaqMan probes were designed based on the comparison of PPRV genome sequences available in GenBank. The duplex real-time RT-PCR results showed that the detection limits for vaccine strain and wild-type strains were both 10 copies per reaction. The developed assay also showed high ampliifcation efifciency,linearity and speciifcity in discriminating the two PPRV types. A total of 136 clinical samples tested by the conventional RT-PCR were run again by the duplex real-time RT-PCR. The results were conifrmed subsequently by sequencing the positive conventional RT-PCR products. This reliable and rapid duplex real-time RT-PCR assay would be feasible and attractive for diagnostic laboratories,both for clinical purpose in active surveillance and for epidemiological investigations.关键词
