DNA vaccination entails administration of the DNA itself encoding antigen to direct synthesis of the antigen directly in the target organism. The target organism's immune system recognizes the antigen, and generates humoral (antibody)- and/or cell-mediated immune response. DNA vaccines afford numerous advantages over conventional vaccines, including ease of production, stability and transport. ⋯ DNA vaccination is beginning to be explored for many pathogens of veterinary interest. The status of DNA vaccines in poultry, livestock and companion animals is reviewed here. While examples of DNA vaccines being tested in the veterinary field are not numerous, the early studies highlight the potential DNA vaccinology offers in veterinary medicine.
