Antimicrobial constituents of Artemisia afra Jacq. ex Willd. against periodontal pathogens
The phytochemical investigation of an ethanol extract of Artemisia afra, led to the isolation of six known compounds, Acacetin (1) 12α,4α-dihydroxybishopsolicepolide (2), Scopoletin (3) α-amyrin (4), Phytol (5) and a pentacyclic tri-terpenoid Betulinic acid (6). The isolated compounds were …

Differential Stimulation of Monocytes to Secrete Secretory Leukocyte Protease Inhibitor by Lipopolysaccharide of Periodontal Pathogens
… studies from our lab demonstrated that LPS of periodontal pathogens suppresses neutrophil's ability to secrete super oxide ions and also shown it to interfere with neutrophil chemotaxis. These factors are believed to aid the pathogens to remain "stealthy" and avoid killing by the mononuclear …

Inhibition of Monocyte Chemotaxis and Chemokine Macrophage Inflammatory Protein-1 Alpha, and Interleukin-8 Secretion by Lipopolysaccharide Isolated from Periodontal Pathogens
<p>The vast majority of periodontal pathogens are classified as gram negative bacteria. These bacteria have an outermost membrane consisting of lipopolysaccharide (LPS), a molecule that can act as an endotoxin and elicit an immune response. The lipopolysaccharide structure consists of three major …

Comparison of Antibacterial Activity of Ozonated Olive Oil and Chlorhexidine Gluconate
… with chlorhexidine gluconate (CHX) against periodontal pathogens, Porphyromonas gingivalis and Aggregatibacter Actinomycetemcomitans. Materials and Methods: The antibacterial activity of two antiseptics, OzOO and CHX, and, two controls, olive oil and normal saline was assessed by disk …

Microbiology of periodontal disease in Singapore and the discovery of a bacterial intron in Actinobacillus actinomycetemcomitans
Ethnicity is a risk factor for periodontal disease. The occurrence of major periodontal pathogens in a total of 410 periodontally healthy and diseased subjects in the ethnic Chinese in Singapore were determined. Actinobacillus actinomycetemcomitans cdt; Porphyromonas gingivalis prtC and Tannerella …

DNA-DNA Checkerboard Hybridization to Identify Bacteria in Human Plaque Samples
… used anaerobic cultural procedures. Some periodontal pathogens are either uncultivable or very difficult to grow, such as<em> Prevotella intermedia, P. nigrescens</em>, and <em>Eubacterium brachy</em>. Digoxygenin probes were prepared for 15 oral bacteria. These probes were used with a …

Relationship of Periodontal Status and Periodontal Infection with Coronary Artery Disease // Връзка на пародонталния статус и пародонталната инфекция с коронарната болест
… the relationship between the severity of periodontal disease, measured by clinical indicators of periodontal status, and the severity of coronary disease, measured by the SYNTAX score, in 199 patients. The influence of infection with three known periodontal pathogens: Aggregatibacter …

Neutrophil extracellular traps in periodontitis
… NET release. In addition, an extensive panel of periodontal pathogens was screened for two potential virulence traits that may confer a survival advantage when challenged with NETs. Deoxyribonuclease (DNase) secretion, capable of degrading NETs, and resistance to killing by histone, a core …

Oral epithelium in the pathogenesis of periodontitis
… line (H400) in order to investigate responses to periodontal pathogen stimulation (P. gingivalis and F. nucleatum) in terms of NF-\(\kappa\)B activation, differential gene expression and cytokine production. The pathogenesis of periodontitis suggests that susceptible patients exhibit a …

Association Between Periodontitis and Hyperglycemia and Metabolic Syndrome Components
… study the roles of C-reactive protein (CRP) and periodontal pathogens (Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis).</p> <p>RESEARCH DESIGN AND METHODS : Participants in the National Health and Nutrition Examination Survey III aged 20 years and older who received …

Complement evasion strategies of human pathogens - the evolutionary arms race
… is centrally involved in host defense against pathogens, its overactivation or deregulation may excessively amplify inflammation and contribute to immunopathology. Periodontitis, an oral infection-driven chronic inflammatory disease, has been linked with complement disruption by periodontal …

Metagenomic analysis of the periodontal and peri-implant microbiome: a link between health and disease status
… and disease profiles of the oral microbiome in periodontal and peri-implant diseases by 16S rRNA gene sequencing, to have a broader and more overall view of the trends of the oral microbial community. Data have shown the greatest bacterial richness in health sites, where Lautropia appeared as a …

Antimicrobial Activity of Human Leukocyte Defensin HNP-4 Against Gram-negative Bacteria
… actinomycetemcomitans (A.a.) and other periodontal pathogens are gram-negative. These bacteria are resistant to HNP 1-3. Defensin-resistance may contribute to the ability of these bacteria to cause disease. There have been no studies of HNP-4 activity against oral bacteria, because HNP-4 …

Aetiological links between oral pathogens and dementia.
… studies support an association between periodontal disease and Alzheimer’s disease (AD). Poorly managed oral hygiene together with the immunosuppressed status of demented patients appears central to this hypothesis as together they contribute not only to an increased incidence of oral …

Pronthocyanidin-Rich Cranberry-FractionInduced Alteration of Periodontal Pathogen Lipopolysaccharide Functions
… of urinary tract colonization by bacterial pathogens. The proanthocyanidin rich cranberry fraction has long been speculated to possess the capacity to reduce the production of inflammatory mediators by LPSstimulated macrophages and gingival fibroblasts and to inhibit host extracellular …
