Abstract:
ORF1 and ORF2 gene of porcine circovirus type 2 were cloned by PCR with the specific primers designed according to genome of PCV2 (AY035820). Following extraction and digestion, PCR products were subsequently inserted into universal transfer vector plECMV (deleted partial gE and gI of pseudorabies virus) to generate recombinant transfer plasmid pIEORF1-ORF2. The genomic DNA of PRV TK-/gE- /LacZ+ strain and pIEORF1-ORF2 were co-transfected into IBRS-2 cells with lipofectin, and recombinant virus TK- /gE- /gI- /ORF1-ORF2+ was selected by PCR with ORF1 gene and ORF2 gene primers respectively. The recombinant virus was analyzed with Southern blotting and Western blotting. The results indicated that ORF1 and ORF2 gene of PCV2 had been inserted into the genome of TK- /gE- /LacZ+ strain and the expressed ORF1-ORF2 fusion protein could react with PCV2 positive sera. Result of virus titers detection showed the insertion of ORF1 and ORF2 gene did not influence propagation of recombinant virus.
