Oral pathogenesis of Aggregatibacter actinomycetemcomitans.

Microbial Pathogenesis, 2017
Aggregatibacter actinomycetemcomitans (A. actinomycetemcomitans) is a Gram-negative, facultative anaerobic bacillus that causes periodontal diseases such as localized aggressive periodontitis (LAP) and. consequently. bone resorption. The potential virulence factors of this organism are powerful leukotoxin, lipopolysaccharide (LPS), cell surface ...

Aggregatibacter actinomycetemcomitans: From Basic to Advanced Research.

Advances in Experimental Medicine and Biology, 2022
Aggregatibacter actinomycetemcomitans is a major periodontal pathogen that was identified firstly in actinomycotic lesions and later in advanced forms of periodontal diseases as well as in oral cavity of healthy subjects. The particular pathogenicity of this specie makes it a target for extensive studies both at fundamental and practical scales.

Is a single session of antimicrobial photodynamic therapy as an adjuvant to non-surgical scaling and root planing effective in reducing periodontal inflammation and subgingival presence of Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans in patients with periodontitis?

Photodiagnosis and Photodynamic Therapy, 2022
OBJECTIVE The aim was to assess the influence of a single session of antimicrobial photodynamic therapy (aPDT) as an adjunct to non-surgical scaling and root planing (SRP) in reducing periodontal inflammation and subgingival presence of Porphyromonas ...

Stability of the JP2 Clone of Aggregatibacter actinomycetemcomitans

Journal of Dental Research, 2009
The JP2 clone of Aggregatibacter actinomycetemcomitans is strongly associated with aggressive periodontitis. To obtain information about colonization dynamics of the JP2 clone, we used PCR to examine its presence in 365 Moroccan juveniles from whom periodontal plaque samples were collected at baseline and after one and two years. Periodontal attachment

Lactobacilli Postbiotics reduce biofilm formation and alter transcription of virulence genes of Aggregatibacter actinomycetemcomitans.

Molecular Oral Microbiology, 2020
Periodontitis is characterized by a dysbiotic microbial community and treatment strategies include the reestablishment of symbiosis by reducing pathogens abundance.

Aggregatibacter Actinomycetemcomitans in Down's Syndrome Children

Journal of Clinical Pediatric Dentistry, 2012
Objectives: To investigate the presence of Aggregatibacter actinomycetemcomitans (Aa) in Down's syndrome (DS) children in comparison with age-matched normal children and to determine if Aa was acquired during childhood in DS individuals. Study design: 60 DS children and 60 healthy children participated in this cross-sectional study.

Role of Aggregatibacter actinomycetemcomitans in glutathione catabolism

Oral Microbiology and Immunology, 2009
Introduction:  Our previous studies demonstrated that three enzymes, γ‐glutamyltransferase (GGT), cysteinylglycinase (CGase) and cystalysin, are required for the catabolism of glutathione to produce hydrogen sulfide (H2S) in Treponema denticola. In this study, we examined glutathione catabolism in Aggregatibacter actinomycetemcomitans.Methods:  The GGT
