Introduction
Porphyromonas gingivalis belongs to the phylum Bacteroidetes and is a non-motile, Gram-negative, rod-shaped, anaerobic pathogenic bacterium. It forms black colonies on blood agar. Collagen degradation that is observed in chronic periodontal disease results in part from the collagenase enzymes of this species. It has been shown in an in vitro study that P. gingivalis can invade human gingival fibroblasts and can survive in them in the presence of considerable concentrations of antibiotics.
