This invention is directed to preparation and expression of synthetic genes encoding polypeptides containing protective epitopes of botulinum neurotoxin (BoNT). The invention is also directed to production of immunogenic peptides encoded by the synthetic genes, as well as recovery and purification of the immunogenic peptides from recombinant organisms. The invention is also directed to methods of vaccination against botulism using the expressed peptides.

Recombinant vaccine against botulinum neurotoxin

This invention is directed to preparation and expression of synthetic genes encoding polypeptides containing protective epitopes of botulinum neurotoxin (BoNT). The invention is also directed to production of immunogenic peptides encoded by the synthetic genes, as weel as recovery and purification of the immunogenic peptides from recombinant organisms. The invention is also directed to methods of vaccination against botulism using the expressed peptides.

Antibodies which neutralize botulinum neurotoxin serotype F are produced using biologically active botulinum neurotoxin instead of toxoid for immunization and exploiting the importance of cross reaction between various serotypes to obtain immune responses, or monoclonal antibodies, to additional serotypes of interest. Methods of preparation and uses of the neutralizing botulinum neurotoxin antibodies are described.
