title: [Construction and identification of recombinant BHV-1 expressing foot and mouth disease virus VP1 gene].
abstract: OBJECTIVE
  In order to construct the recombinant bovine hepervirus-1 (BHV-1) which expressed foot and mouth disease virus (FMDV) VP1 gene, we constructed a BHV-1 gE gene transfer vector by inserting the synthetic VP1 gene of FMDV (O/China/99) under the immediate-early promoter of cytomegalovirus.
  
  
  METHODS
  The mixtures of parental virus (BHV-1/gE(-)/LacZ+) DNA and transfer vector was transfected into bovine turbinate cells using calcium phosphate-mediated transfection. Then the propagated viruses were harvested. The recombinant BHV-1 (designated BHV-1/gE(-)/VP1) was obtained by selection for white virus plaques.
  
  
  RESULTS
  PCR results showed that VP1 gene was successfully inserted into the genome of BHV-1/gE(-). The expression of VP1 in infected cells was proved by indirect immunofluorescence assay and Western blotting.
  
  
  CONCLUSIONS
  The research provided a basis for development of BHV-1 vector vaccines for FMD and other important bovine infectious diseases.
