  • Publication number: 20230355734
    Abstract: Provided herein are recombinant Factor H Binding Protein B (FhbB) chimeric proteins comprising several different mutant variants of the Treponema denticola Factor H binding protein B (FhbB). The mutant variants cannot bind Factor H. The chimeric proteins are used to vaccinate subjects against periodontal disease either systemically and/or by direct application of antibodies generated against the chimeric proteins to the oral cavity (e.g. the gums) of a patient to prevent and/or treat periodontal disease.

  • Publication number: 20220152180
    Abstract: Provided herein are chimeric recombinant polypeptides (chimeritopes) for use in vaccines against Anaplasmosis, in assays for diagnosing Anaplasmosis and in assays for measuring antibody titers induced by vaccination. The chimeritopes comprise, for example, antigenic segments of three Anaplasma proteins (OmpA, AipA and Asp14) and a non-antigenic segment of a Borrelia Osp protein (e.g. OspC) that is 10 amino acids in length, proline rich and random coil in conformation. Compositions comprising the chimeritopes, optionally in combination with additional Anaplasma proteins of interest, are also provided, as are methods of using the compositions as vaccines and diagnostic tools.

  • Patent number: 10466240
    Abstract: Chimeric polyvalent recombinant proteins for use as vaccines and diagnostics for Lyme disease (e.g. in canines and humans) are provided. The chimeric proteins comprise epitopes of the loop 5 region and/or the alpha helix 5 region of outer surface protein C (OspC) types and/or OspE types. The OspC types may be associated with mammalian Borrelia infections.

  • Patent number: 10266571
    Abstract: Antigenic polypeptides comprising linear immunodominant epitopes of Borrelia outer surface protein A (OspA) or Borrelia outer surface protein C (OspC) are useful as vaccines against Lyme disease, and as diagnostics for detecting Borrelia infections. The OspA and OspC antigenic polypeptides typically comprise a plurality of peptides representing epitope containing regions from multiple distinct phyletic groups. The antigenic polypeptides may also include epitopes from both Borrelia OspA and Borrelia OspC.

  • Patent number: 10086057
    Abstract: Stage-specific Borrelia antigens for diagnosing, treating and/or preventing Lyme disease are provided. The antigens include chimeric Borrelia antigen constructs and mutant recombinant proteins comprising OspC and OspE epitopes, respectively. The antigens are used in multiprotein assays that differentiate early, middle and late stage infection, and/or in vaccine preparations.
