as osteoclasts. The function of osteoclasts was assessed by measuring the areas of pits absorbed. Inflammatory cytokine genes expressions, such as interleukin (IL)-1b, IL-6, and
tumor necrosis factor (TNF)-a, were examined by RT-PCR analysis using murine peritonealmacrophages. Experimental periodontitis was performed in Sprague-Dawley rats orally
infected with A. naeslundii.
Results: TRAP-positive multi-nuclei cells and the areas of pits induced by peptidoglycan
were significantly greater than controls ( p < 0.01). Gene expression levels of IL-1b, IL-6, and
TNF-a induced by A. naeslundii PGN were stronger than controls. In experimental periodontitis,
bone loss of A. naeslundii-infected rats was comparable to that of rats induced by
Porphyromonas gingivalis, which has been reported to be a periodontal pathogenic agent,
being significantly greater than that of the sham group ( p < 0.01).
Conclusions: These results suggest that peptidoglycan of A. naeslundii is an important virulence
factor in the development of periodontitis.
