COMPOSITIONS AND METHODS OF ENHANCING IMMUNE RESPONSES TO ENTERIC PATHOGENS

摘要

Vaccine vectors capable of eliciting an immune response to enteric bacteria and methods of using the same are provided. The vaccine vectors include a polynucleotide encoding a PAL polypeptide. The PAL polypeptide may be expressed on the surface of the vaccine vector. The vaccine vector may also include a second polypeptide encoding an immunostimulatory polypeptide such as a CD 154 polypeptide or an HMGB1 polypeptide.
