Porphyromonas gingivalis -Specific Immunoglobulin G Prevents P. gingivalis -Elicited Oral Bone Loss in a Murine Model

Active immunization with Porphyromonas gingivalis whole-cell preparations has been shown to prevent P. gingivalis infection and oral bone loss. Employing passive antibody transfer and opsonization, we demonstrate with this study that immunization-elicited P. gingivalis-specific immunoglobulin G facilitates clearance of P. gingivalis in a subcutaneous chamber model and prevents P. gingivalis-elicited oral bone loss.
