Abstract: Peptides generated from a random library that are bound by a monoclonal antibody to Chlamydial glycolipid exoantigen (GLXA) and thus mimic this antigen are disclosed. Peptides that correspond to antigen-binding regions of an anti-idiotypic antibody (mAb2) specific for anti-GLXA antibody (Ab1) which act as molecular mimics of GLXA are also disclosed used as immunogens to induce broadly reactive genus-specific anti-chlamydial antibodies. These peptides and immunogenic DNA encoding the mAb2-like peptides, microparticle or nanoparticle formulations and other formulations of these peptides are disclosed as are methods for immunizing subjects to obtain genus-specific anti-chlamydial antibodies and to treat or prevent Chlamydia-associated or induced rheumatoid arthritis.

Abstract: The invention relates to a method of treating Alzheimer's disease in a mammal comprising administering to the mammal an anti-microbial agent having anti-Chlamydia pneumoniae activity. The invention also relates to a method of diagnosing Alzheimer's disease in a mammal comprising measuring the serum anti-Chlamydia pneumoniae antibody titer in a patient suspected of having Alzheimer's disease.

Abstract: Subsequent to reports that Chlamydia pneumoniae (Cpn) was present in the CSF of a subset of multiple sclerosis (MS) patients, a 20-mer peptide from a protein specific to C. pneumoniae (Cpn) which shares a seven amino acid motif with a critical epitope of myelin basic protein (MBP), a major central nervous system antigen targeted by the autoimmune response in MS was identified. This bacterial peptide induces a Th1 response accompanied by severe clinical and histological experimental autoimmune encephalomyelitis in Lewis rats, a condition closely reflective of many aspects of MS. Various non-encephalitogenic peptide analogues and derivatives are disclosed and are useful for inhibiting such Th1 responses, inducing protective Th2 responses, and for treating a subject having MS or delaying onset of preventing MS in a subject at risk.

Abstract: A genus specific chlamydia vaccine is provided which comprises an anti-idiotype antibody capable of producing in an animal an anti-anti-idiotypic antibody which recognizes a glycoplipid exoantigen (GLXA) of chlamydia. The vaccine is produced by producing an idiotypic antibody to GLXA which, in turn, is utilized t produce the anti-idiotypic antibody comprising the vaccine.

Abstract: A genus specific chlamydia oral or injectable vaccine is provided which comprises an anti-idiotype antibody capable of producing in an animal an anti-idiotypic antibody or Fab fragment thereof enclosed in microspheres formed of a pharmacologically acceptable polymer is capable of producing in an animal an anti-anti-idiotypic immune response (serum antibody, secretory antibody or T-cell responsee) which recognizes a glycolipid exoantigen (GLXA) of chlamydia. The oral or injectable vaccine is produced from an idiotypic antibody to GLXA which, in turn, is utilized to produce the anti-idiotypic antibody.
