Association between Gram-Negative Enteric Rods, Porphyromonas gingivalis and Changes in Clinical Parameters in Chronic Periodontitis: An Observational Study
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...
متن کاملBeta-lactamase in gram-negative rods: the relationship between penicillinase and R plasmids in gram-negative rods.
Concomitant with the extensive use of antibiotics, the number of multiple antibiotic-resistant strains has been increasing. Since resistance is mainly mediated by R plasmids, we undertook to investigate the characteristics of R plasmid-determined beta-lactamase in 6 Gram-negative rods. The beta-lactamase produced by each organism was classified by its substrate: type P which attacks penicillins...
متن کاملPositive correlations between presence of gram negative enteric rods and Porphyromonas gingivalis in subgingival plaque.
The association between Gram negative enteric rods and Porphyromonas gingivalis in periodontal diseases has received little attention in the literature. Thus, the aim of this study was to investigate the associations between Gram negative enteric rods, Porphyromonas gingivalis and clinical parameters of periodontal disease. The prevalence of Gram-negative enteric rods and P. gingivalis were exa...
متن کاملLeukotoxic Activity of Aggregatibacter actinomycetemcomitans and Periodontal Attachment Loss
Aggregatibacter actinomycetemcomitans is a Gram-negative periodontitis-associated bacterium that expresses a toxin that selectively affects leukocytes. This leukotoxin is encoded by an operon belonging to the core genome of this bacterial species. Variations in the expression of the leukotoxin have been reported, and a well-characterized specific clonal type (JP2) of this bacterium with enhance...
متن کاملRole of Exopolysaccharide in Aggregatibacter actinomycetemcomitans–Induced Bone Resorption in a Rat Model for Periodontal Disease
Aggregatibacter actinomycetemcomitans a causative agent of periodontal disease in humans, forms biofilm on biotic and abiotic surfaces. A. actinomycetemcomitans biofilm is heterogeneous in nature and is composed of proteins, extracellular DNA and exopolysaccharide. To explore the role played by the exopolysaccharide in the colonization and disease progression, we employed genetic reduction appr...
