Porphyromonas gingivalis W50 (ATCC 53978) possesses the gene for fimbriae; however,
the surface-expressed fimbriae are sparse and have not been previously isolated and …

Interactions between Porphyromonas gingivalis and gingival epithelial cells were
investigated. Gingival epithelial cells were cultured from surgically removed gingival tissue …

Fimbriae are major adhesive components on the cell surface of Porphyromonas gingivalis.
In this study, we evaluated the role of fimbriae in coaggregation with Streptococcus oralis …

Background: Porphyromonas gingivalis., a key pathogen in periodontitis, is able to adhere to
and invade the pocket epithelium. Different capsular antigens of P. gingivalis have been …

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 …

Porphyromonas gingivalis cells coaggregated with Prevotella intermedia cells. The
coaggregation was inhibited with l‐arginine, l‐lysine, Nα‐p‐tosyl‐l‐lysine chloromethyl …

While classical studies on host-parasite interactions have considered a “virulence factor” to
be a molecule (s) that exerts a detrimental effect (that is, toxin) on a host cell, recent …

In this study, we examined the effects of selected environmental factors on the adhesion of
Porphyromonas gingivalis fimbriae, an important structure involved in attachment of the …

To further investigate the relationship between fimbriae and the hemagglutinating adhesin
HA-Ag2 of Porphyromonas gingivalis, three spontaneous mutants of the type strain ATCC …

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) …
