The relationship between rheumatoid arthritis and poor oral health has been recognised for many decades. The association between periodontal infection and the risk of developing RA has been the subject of epidemiological, clinical and basic science research in recent times. Converging and reproducible evidence now makes a clear case for the role of specific periodontal infective pathogens in in...

There is an error in the fourth sentence of the Abstract. The correct sentence is: This increase was entirely CD36/SR-B2-dependent, as there was no significant change in lesion burden between infected and uninfected Cd36 o /Ldlr o mice.

Induction of mucosal immune responses against Porphyromonas gingivalis within the oral cavity of dogs was studied by immunizing with pH-sensitive fusogenic polymer (MGluPG)-modified liposome-associated cell lysate. Dogs immunized with P. gingivalis cell lysate-containing MGluPG-modified liposomes by intraocular (eye drop) route displayed significant levels of P. gingivalis cell lysate-specific ...

Multilocus sequence typing and fimA genotyping were performed on Porphyromonas gingivalis isolates from 15 subjects with "refractory" periodontitis. Several sequence types were detected for most individual pockets. The variation indicated recombination at the recA and pepO genes. The prevalence of fimA genotypes II and IV confirmed their association with periodontitis.

OBJECTIVE Although the exact reason is not known, encapsulated gram-negative Porphyromonas gingivalis strains are more virulent than non-encapsulated strains. Since difference in virulence properties may be due to difference in cytokine production following recognition of the bacteria or their products by the host inflammatory cells, we compared cytokine production following stimulation with ba...
