Abstract:

In order to develop a multiplex RT-PCR method for detecting three genotypes of bovine parainfluenza virus type 3 (BPIV3), according to the hemagglutinin-neuraminidase protein genomic sequences of three BPIV3 genotypes obtained from GenBank, three pairs of specific PCR primers were designed. A multiplex RT-PCR detecting three genotypes of BPIV3 was established and optimized. The results showed no cross-reactivity with IBRV, BRSV, BVDV, M.bovis, PPRV, B.melitensis, B.abortus, bovine P.multocida serotype A and bovine P.multocida serotype B. In this study, the amplification produced a series of specific fragments with lengths of 150 bp (BPIV3a), 253 bp (BPIV3b) and 342 bp(BPIV3c), respectively. The limit detection of three recombinant plasmids were 0.89×104, 0.92×104 and 1.53×104 copies/μL. This multiplex RT-PCR method was high specificity and simplicity of operator. It was applied to detect clinical samples and could rapidly detect three genotypes of BPIV3.
