Porphyromonas gingivalis is recognized as an important etiological agent in adult periodontal disease. There is growing evidence that P. gingivalis is related to other chronic and systemic diseases such as cardiovascular diseases and adverse pregnancy outcomes. P. gingivalis expresses many virulence factors such as hemagglutinins, fimbriae, lipopolysaccharides, capsular material and proteases that have been implicated in its pathogenesis. We are currently sequencing four strains of P. gingivalis. The availability of complete whole genome sequences from multiples strains of P. gingivalis will be important for comparative genomics. Such analysis will enable us to detect the gain or loss of genes including virulence genes, to compare metabolic pathways, and to provide insights into mechanisms of pathogenicity.​
