Abstract: The present invention relates to vaccines for control of Borrelia infections in animal and human populations. In particular, the present invention provides compositions and methods comprising recombinant bacteria engineered to express one or more Borrelia burgdorferi antigens for use as Lyme disease vaccines. In some embodiments, the recombinant bacteria are freeze-dried.

Abstract: The present invention relates, e.g., to an isolated peptide consisting of the sequence MKKDDQIAAAIALRGMA (SEQ ID NO:1) or an active variant thereof, wherein the peptide or active variant can bind specifically to an antibody induced by a causative agent of Lyme disease (a pathogenic Borrelia), e.g. in a sample from a subject having Lyme disease. Also disclosed are linear multimeric peptides that contain the peptide represented by SEQ ID NO:1 as well as one or more additional peptide epitopes from other Borrelia proteins that can also bind specifically to an antibody as above. Compositions and diagnostic kits comprising a peptide of the invention are described, as are diagnostic assays using the peptide(s).

Abstract: The present invention is drawn to an immunogenic composition comprising OspC polypeptides from Lyme Disease causing Borrelia. In one embodiment, the immunogenic composition of the present invention comprises at least one OspC polypeptide or immunogenic fragment thereof from each of Borrelia burgdorferi OspC families A, B, I and K. In another embodiment, the immunogenic composition of the present invention comprises at least one OspC polypeptide or immunogenic fragment thereof from each of Borrelia afzelii OspC families A and B.

Abstract: Novel chimeric nucleic acids, encoding chimeric Borrelia proteins comprising OspC or an antigenic fragment thereof and OspA or an antigenic fragment thereof, are disclosed. Chimeric proteins encoded by the nucleic acid sequences are also disclosed. The chimeric proteins are useful as vaccine immunogens against Lyme borreliosis, as well as for immunodiagnostic reagents.
