The association of vascular reactivity between diabetes and periodontal disease has not been clarified. Gingival blood flow was measured by laser Doppler flowmetry for 31 weeks in Wistar rats, Wistar rats orally challenged with Porphyromonas gingivalis (Wistar rats + Porphyromonas gingivalis), Goto-Kakizaki rats, and Goto-Kakizaki rats orally challenged with Porphyromonas gingivalis (Goto-Kakiz...

materials and methods the subjects included 27 male and 3 female patients with advanced chronic periodontitis. the mean age of the patients was 47.6 ± 2.0 years old. p. gingivalis was isolated from the samples and identified by various diagnostic tests, including gram staining, indol test, and fluorescent test. minimum inhibitory concentration (mic) of the essential oil against isolated p. ging...

Porphyromonas gingivalis is considered as a major etiological agent in periodontal diseases and implied to result in gingival inflammation under orthodontic appliance. rag locus is a pathogenicity island found in Porphyromonas gingivalis. Four rag locus variants are different in pathogenicity of Porphyromonas gingivalis. Moreover, there are different racial and geographic differences in distrib...

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...

The oral bacterial species Porphyromonas gingivalis, a periodontal pathogen, has plastic genomes that may be driven by homologous recombination with exogenous deoxyribonucleic acid (DNA) that is incorporated by natural transformation and conjugation. However, bacteriophages and plasmids, both of which are main resources of exogenous DNA, do not exist in the known P. gingivalis genomes. This cou...

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...

ABSTRACT Porphyromonas gingivalis is implicated in chronic and aggressive periodontitis. This bacterium has numerous virulence factors and one is the fimbriae, which is quite important for bacterial colonization. Fimbriae are appendices that anchor to the bacterial wall and are comprised of the protein fimbriline encoded by the fimA gene. Thus far, six genotypes have been identified, fimA I to ...

Introduction: Biofilm formation on implants is the primary factor for implant loss. Porphyromonas gingivalis a highly virulent pathogen that contributes to development of periodontal disease and failure.
