Abstract
Objectives:  Heat shock protein (HSP) can be utilized as a vaccine to cross‐protect against multiple pathogenic species. The present study was performed to evaluate Porphyromonas gingivalis heat shock protein 60 (HSP60) as a vaccine candidate to inhibit multiple bacteria‐induced alveolar bone loss.Material and methods:  Recombinant P. gingivalis HSP60 was produced and purified from P. gingivalis GroEL gene. Rats were immunized with P. gingivalis HSP60, and experimental alveolar bone loss was induced by infection with multiple periodontopathogenic bacteria.Results:  There was a very strong inverse relationship between postimmune anti‐P. gingivalis HSP immunoglobulin G (IgG) levels and the amount of alveolar bone loss induced by either P. gingivalis or multiple bacterial infection (p = 0.007). Polymerase chain reaction data indicated that the vaccine successfully eradicated the multiple pathogenic species.Conclusions:  We concluded that P. gingivalis HSP60 could potentially be developed as a vaccine to inhibit periodontal disease induced by multiple pathogenic bacteria.
