Cytokine Degradation by Biofilms of Porphyromonas gingivalis
Current Microbiology, 1998The aim of this study was to determine whether biofilms of Porphyromonas gingivalis could proteolytically degrade the cytokines interleukin (IL)-1beta, IL-6, or IL-1 receptor antagonist (IL-1ra). Biofilms were grown on membrane filters on the surface of Wilkins-Chalgren blood agar. The biofilms were removed from the plates, and solutions containing 2.5

Pleiotropic pigmentation mutants of Porphyromonas gingivalis
Microbial Pathogenesis, 2000Porphyromonas gingivalis is a Gram-negative, black pigmented oral anaerobe associated with adult periodontitis. The adherence of the bacterium to junctional epithelial cells is the first step in infection and colonization. The molecular mechanisms and genetics of colonization are, as yet, not well understood, although it has been demonstrated that P ...

Putative Respiratory Chain of Porphyromonas gingivalis
Future Microbiology, 2010The electron transfer chain in Porphyromonas gingivalis, or periodontopathogens, has not yet been characterized. P. gingivalis, a strict anaerobic bacteria and the second colonizer of the oral cavity, is considered to be a major causal agent involved in periodontal diseases. Primary colonizers create a favorable environment for P.

Effect of Transferrin on the Growth of Porphyromonas gingivalis
Journal of Dental Research, 1991This study describes the effect of transferrin as an iron source on the growth of Porphyromonas (formally Bacteroides) gingivalis. Bacterial growth was monitored spectrophotometrically. All strains of P. gingivalis tested grew well in medium containing transferrin. The growth of P.

Structural studies on Porphyromonas gingivalis proteins
2023[eng] We investigated the structure function relationship of PorX by combined biophysical experiments and enzymatic assays. As a regulator of the type 9 secretion system (T9SS) of the human pathogen Porphyromonas gingivalis (PG), PorX is responsible for PG virulence[1] and as drug target could be the key in disease prevention.
