OBJECTIVES The aim of this study was to determine the prevalence of the different fimA genotypes of Porphyromonas gingivalis in adult Spanish patients with chronic periodontitis, patients with gingivitis and periodontally healthy subjects, and the relationship between these genotypes and other periodontopathogenic bacteria. STUDY DESIGN Samples of subgingival plaque were taken from 86 patient...

The correlation between Gram negative enteric rods and Porphyromonas gingivalis in periodontal diseases has received little attention in the literature. The objective of this study was to investigate the association between gram negative enteric rods and Porphyromonas gingivalis and changes in clinical parameters in chronic periodontitis subjects. Occurrence of Gram negative enteric rods, Porph...

Necrotic dental root canal infections are polymicrobial infections dominated by anaerobic bacteria. The number of different species in one canal is usually low, approx. 4-7 species. The species isolated most frequently belong to the genera Prevotella, Porphyromonas, Fusobacterium, Peptostreptococcus, Eubacterium and Streptococcus. The frequency of isolation of black-pigmented Gram-negative anae...

background and objectives: gingival and periodontal diseases are associated with specific bacterial infections. the main aim of the study was to know whether the periodontitis is associated with an increased risk for acute myocardial infarction (ami) and to know the distribution of porphyromonas gingivalis in patients with acute myocardial infarction associated with chronic periodontitis and ac...

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.

Two distinctive types of fimbriae have been identified in Porphyromonas gingivalis. In this report, we demonstrate that minor fimbriae are involved in P. gingivalis autoaggregation and colonization. A mutant with a deficiency in minor fimbriae can bind to a saliva-coated surface but does not form microcolonies as the wild-type strain does.
