Abstract
The present invention relates to a new vaccine delivery system. In particular, the present invention includes compositions and methods of integrally transformed non-pathogenic, commensal bacteria that can express a nucleic acid molecule of a foreign polypeptide, wherein the nucleic acid molecule that encodes the foreign polypeptide is stably integrated into genomic DNA of the bacteria. The foreign polypeptide includes a vaccine antigen that elicits an immunogenic response, an inhibitor of a pathogen, or an immune booster or modulator.
Claims8
An integrally transformed non-pathogenic, commensal bacterium that expresses a synthetic nucleic acid molecule encoding a foreign fusion polypeptide comprising a C. difficile antigen and a signal polypeptide therein, wherein the synthetic nucleic acid molecule is stably integrated into genomic DNA of the bacterium, wherein the bacterium is Streptococcus mitis, and wherein the synthetic nucleic acid molecule comprises a TcdA/TcdB fusion construct having SEQ ID NO:81.
