Abstract: The invention describes an adjuvant composition comprising an antimicrobial agent, in particular an azalide, wherein the antimicrobial agent acts as an adjuvant. More particularly, the adjuvant composition is a vaccine adjuvant. The invention further describes a vaccine comprising several components comprising (a) at least one antigen and (b) at least one antimicrobial agent, in particular an azalide, wherein the azalide acts as an adjuvant. An adjuvant composition or vaccine of the present invention is useful in the prevention and treatment of diseases caused by a pathogenic agent, a cancerous cell, or an allergen.

Abstract: The present invention relates to novel bacterial isolates identified by their 16S rRNA DNA, that cause periodontal disease in companion animals, and vaccines comprising such bacteria. Also provided are methods for treating and preventing periodontal disease and kits for detecting and treating periodontal disease kits for detecting and preventing periodontal disease.

Abstract: Methods to measure the duration of adequate immune memory for animal vaccines involving a retrospective analysis utilizing veterinary vaccine administration histories and clinical histories, and markers of immunity of animals in the field to derive a vaccine's duration of adequate immune memory.

Abstract: The present invention relates to novel bacterial isolates identified by their 16S rRNA DNA, that cause periodontal disease in companion animals, polynucleotide sequences contained therein, polypeptides encoded by such polynucleotide sequences and vaccines comprising such bacteria, polynucleotides, or polypeptides. Also provided are methods for treating and preventing periodontal disease and kits for detecting and treating periodontal disease kits for detecting and preventing periodontal disease. In addition, methods for assessing the efficacy of a vaccine against periodontal diseases in an animal are provided.
