Novel fimbrilin PGN_1808 in Porphyromonas gingivalis
Porphyromonas gingivalis, a periodontopathic gram-negative anaerobic bacterium, generally expresses two types of fimbriae, FimA and Mfa1. However, a novel potential fimbrilin, PGN_1808, in P. gingivalis strain ATCC 33277 was recently identified by an in silico structural homology search. In this study, we experimentally examined whether the protein formed a fimbrial structure. Anion-exchange ch...
متن کاملPorphyromonas 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...
متن کاملPorphyromonas 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...
متن کاملPorphyromonas gingivalis fimbriae
Marginal periodontitis is not a homogeneous disease but is rather influenced by an intricate set of host susceptibility differences as well as diversities in virulence among the harbored organisms. It is likely that clonal heterogeneity of subpopulations with both high and low levels of pathogenicity exists among organisms harbored by individuals with negligible, slight, or even severe periodon...
متن کاملDraft Genome Sequence of Porphyromonas gingivalis Strain Ando Expressing a 53-Kilodalton-Type Fimbrilin Variant of Mfa1 Fimbriae
Periodontopathic Porphyromonas gingivalis strain Ando abundantly expresses a 53-kDa-type Mfa1 fimbria. Here, we report the draft genome sequence of Ando, with a size of 2,229,994 bp, average G+C content of 48.4%, and 1,755 predicted protein-coding sequences.
