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 …

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 …

Isogenic mutants of Porphyromonas gingivalis which differ in the expression of fimbriae
were used to examine the contribution of fimbriae in invasion of a human oral epithelial cell …

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 …

Porphyromonas gingivalis, a periodontal pathogen, can invade primary cultures of gingival
epithelial cells. Optimal invasion occurred at a relatively low multiplicity of infection (ie, 100) …

The invasion of gingival epithelial cells by certain pathogenic periodontal bacteria may
account for their presence within diseased gingival tissue. To dissect the initial steps of a …

The adherence of Porphyromonas gingivalis to cell surfaces of periodontal tissues may play
an important role in its pathogenicity. In this study, 12 strains of P. gingivalis, including both …

Interaction between the major fimbriae of Porphyromonas gingivalis and gingival epithelial
cells is important for bacterial adhesion and invasion. In this study, we identified integrins as …

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 …
