Porphyromonas gingivalis strain diversity.

Porphyromonas gingivalis is implicated in the etiology of chronic periodontitis. Genotyping studies suggest that genetic variability exists among P. gingivalis strains; however, the extent of variability remains unclear and regions of variability remain largely unidentified. To assess P. gingivalis strain diversity, we previously used heteroduplex analysis of the ribosomal operon intergenic spa...

Genome Sequence of Porphyromonas gingivalis Strain A7436.

Porphyromonas gingivalis is strongly associated with periodontitis. P. gingivalis strain trafficking and tissue homing differ widely, even among presumptive closely related strains, such as W83 and A7436. Here, we present the genome sequence of A7436 with a single contig of 2,367,029 bp and a G+C content of 48.33%.

Porphyromonas gingivalis strain variability and periodontitis.

To determine if there is variability in virulence among strains of Porphyromonas gingivalis in human periodontitis, their distribution in a group of subjects with clear indicators of periodontitis and in a healthy, age-matched control group was examined. The presence of heteroduplex types of P. gingivalis in the two groups was determined with a PCR-based assay. This assay relied on detection of...

Genome Sequence of Porphyromonas gingivalis Strain AJW4.

Porphyromonas gingivalis is associated with oral and systemic diseases. Strain-specific P. gingivalis invasion phenotypes have been correlated with disease presentation in infected laboratory animals. Here, we present the genome sequence of AJW4, a minimally invasive strain, with a single contig of 2,372,492 bp and a G+C content of 48.27%.

Porphyromonas gingivalis

Editorial Periodontal diseases have long been associated with an increased, yet moderate, risk for the development of atherosclerosis and coronary heart disease. The postulated mechanism underlying this association is the low grade systemic inflammatory response to pathogens engaged in chronic periodontal infection, such as Porphyromonas gingivalis, which may facilitate atheroma formation and t...
