Porphyromonas gingivalis is one of the principal organisms associated with adult
periodontitis. Bacterial surface proteins such as fimbriae and gingipain hemagglutinin …

Porphyromonas gingivalis, a Gram-negative oral anaerobe, interacts with epithelium lining
the gingival sulcus. Continuing our studies on the role of gingipain cysteine proteinases in P …

Porphyromonas gingivalis has been implicated as an etiologic agent of adult periodontitis.
We have previously shown that P. gingivalis can degrade the epithelial cell-cell junction …

Porphyromonas gingivalis is a periodontal pathogen capable of invading primary cultures of
normal human gingival epithelial cells (NHGEC). Involvement of P. gingivalis fimbriae in the …

Proteolytic enzymes produced by Porphyromonas gingivalis are thought to play critical roles
in the pathogenesis of periodontitis. The aim of this study was to investigate the effect of …

The adherence of Porphyromonas gingivalis to host cells is likely a prerequisite step in the
pathogenesis of P. gingivalis-induced periodontal disease. P. gingivalis binds to and …

Porphyromonas gingivalis, a Gram‐negative oral anaerobe, is associated with periodontitis,
a disease that in some form affects up to 80% of the adult population in the USA. The …

Cysteine proteases, including Arg-gingipain of Porphyromonas gingivalis, have been
implicated as important virulence factors in periodontal diseases. These enzymes are also …

Porphyromonas gingivalis fimbriae are classified into six types (types I to V and Ib) based on
the fimA genes encoding FimA (a subunit of fimbriae), and they play a critical role in …

The mechanisms by which Porphyromonas gingivalis, a gram-negative anaerobic
bacterium, is pathogenic for the periodontium remain largely hypothetical. Invasion of host …
