BACKGROUND: A DNA vaccine expressing glycoprotein C (gC) of duck plague virus (DPV) was evaluated for inducing immunity in ducks. The plasmid encoding gC of DPV was administered via intramuscular (IM) injection and gene gun bombardment.
RESULTS: After immunization by both routes virus-specific serum antibody and T-cell responses developed. Vaccination of ducks by IM injection induced a stronger humoral, but weaker cell-mediated immune response. In contrast, a better cell-mediated immune response was achieved by using a gene gun to deliver DNA-coated gold beads to the epidermis with as little as 6 μg of DNA.
CONCLUSIONS: This demonstrated that both routes of DNA inoculation can be used for eliciting virus-specific immune responses. Although DNA vaccine containing DPV gC is effective in both intramuscular injection and gene gun bombardment, the latter could induce significantly higher cell-mediated responses against DPV.
