Abstract: According to the published genome sequences of PRRSV, one pair of spec cprimers were designed toamplify ORF5 gene of L211 strain of GAMS U province by RT-PCR. The ampl}ied fragment was cloned into pFastBacHTAdonor plasmid. The recombinant pFastBacHTA was identified lry digestion with clonuclease enzyme, PCR amplificationand sequencing.Then the purified plasmidwas transformed intDH10Bae-host cells, producing specifc trarsposition withBacmid to yield the recombinant shuttle vehicles, rBacmid-ORF5. The baculovirus cpression vector was successfully corerstrutted, which would be useful for proluction of gene vaccination in future.

Key words: Porcine reproductive and respiratory syndrome virus, ORF5 gene, Cloning, Baculovirus expression
