Abstract Background The use of food-grade lactococci as bacterial carriers to DNA delivery into epithelial cells is a new strategy to develop live oral DNA vaccine. Our goal was to develop a new plasmid named pValac for antigen delivery for use in lactococci. The pValac plasmid was constructed by the fusion of i a eukaryotic region allowing the cloning of an antigen of interest under the control of the pCMV eukaryotic promoter to be expressed .
