  • antigenic composition
    Patent number: 8784831
    Abstract: The present invention provides an antigenic composition, the composition comprising at least one recombinant protein. The recombinant protein comprises at least one epitope. The epitope is reactive with an antibody which is reactive with a polypeptide having the sequence set out in SEQ. ID. NO. 3 or SEQ. ID. NO. 5. The invention also provides methods and compositions for the production of the recombinant protein. Also provided are methods for the diagnosis, treatment and prevention of P. gingivalis infection.

  • Porphyromonas gingivalis recombinant proteins and truncations
    Patent number: 7204991
    Abstract: The present invention relates to soluble P. gingivalis polypeptides derived from PG32 and PG33 and to polynucleotides encoding these polypeptides. The P. gingivalis polypeptides and nucleotides can be used in compositions for use in raising an immune response in a subject against P. gingivalis and treating or preventing or reducing the severity of the condition known as periodontitis or in other conditions related to infection with P. gingivalis.
