AB - The P12A gene fragments and 3C gene fragments
of O/China 99 strains of foot and mouth virus were ligated into bilateral tandem
Vaccinia virus promoter P7.5 which could initiate expression of EGFP
gene and the expression box p-EGFP-N1-P7.5-P12A-3C was constructed. The expression
box was ligated to the linear vector pUC119-TK after KpnI enzyme digestion by
blunt end ligation to obtain the recombinant plasmid pUC119-TK-EGFP-P7.5-P12A-3C.
The homologous recombination took place in the BHK-21 cell between the recombinant
plasmid and the Capripox virus attenuated strain by deleted TK gene.
The PCR identification, the Western blot analysis and immunological experiment
on mice were carried out. The results showed that the recombinant strain could
be subcultured in BHK-21 cell for 10 passages, expressing P12A-3C gene
which was 2900 bp by sequence analysis, the Western blot analysis demonstrated
that the expressed protein of recombinant plasmid pUC119-TK-EGFP-N1-P7.5-P12A-3C
in BHK-21 cells infected GTPV AV41 could be specifically recognized by the hyperimmune
serum to type O FMDV. Immunity assay showed that the expression protein had
immunogenicity in mice. All the results showed that the Goat Pox virus attenuated
strain which could express P12A-3C gene of type O FMDV was obtained.
