Diaphragmatic mass caused by Aggregatibacter actinomycetemcomitams

open access: yesIDCases, 2020
A 52-year-old man was evaluated in our outpatient facility because of a thoracic mass for one month. A needle biopsy of the chest mass was performed and microbiological culture showed growth of Aggregatibacter actinomycetemcomitans.

Porphyromonas gingivalis GroEL exacerbates orthotopic allograft transplantation vasculopathy via impairment of endothelial cell function

open access: yesMolecular Oral Microbiology, EarlyView.
Abstract Orthotopic allograft transplantation (OAT) is a significant approach to addressing organ failure. However, persistent immune responses to the allograft affect chronic rejection, which induces OAT vasculopathy (OATV) and organ failure. Porphyromonas gingivalis can infiltrate remote organs via the bloodstream, thereby intensifying the severity ...

The ComEA/ComEC Operon is Critical for Nitrosative Stress Tolerance by an Oral Commensal

open access: yesMolecular Oral Microbiology, EarlyView.
ABSTRACT Oral commensal streptococci play a large role in mediating microbial homeostasis. Our prior work has demonstrated that hydrogen peroxide (H2O2) produced by oral commensal streptococci can react with salivary nitrite (NO2) and generate peroxynitrite (ONOO−), a potent antimicrobial.

Proteomics of Aggregatibacter actinomycetemcomitans Outer Membrane Vesicles

open access: yesPLOS ONE, 2015
Aggregatibacter actinomycetemcomitans is an oral and systemic pathogen associated with aggressive forms of periodontitis and with endocarditis. Outer membrane vesicles (OMVs) released by this species have been demonstrated to deliver effector proteins such as cytolethal distending toxin (CDT) and leukotoxin (LtxA) into human host cells and to act as ...

Designing Polymerase Chain Reaction for Molecular Diagnostics of the Primary Bacterial Cause of Periodontitis [PDF]

open access: yesJournal of Advanced Biomedical Sciences, 2020
Background & Objective: Periodontal disease, which can become a chronic condition, is an inflammatory disease that upsets the soft and hard structures supporting the teeth. The aim of the present study was to design and develop an in-house PCR Method, to

Aggregatibacter actinomycetemcomitans adhesion inhibited in a flow cell

open access: yesOral Microbiology and Immunology, 2008
Introduction:  Microbial interactions are considered important in the adhesion process of pathogenic bacteria in the oral cavity. This study addressed the hypothesis that a streptococcal biofilm influences the hard tissue colonization by the periodontopathogen Aggregatibacter actinomycetemcomitans under hydrodynamic conditions.Methods:  The ...

Distribution of nicotinamide phosphoribosyltransferase in genus Aggregatibacter and description of Aggregatibacter animalimorsus sp. nov., Aggregatibacter holmi sp. nov., and Aggregatibacter valvarum sp. nov.

open access: yesFrontiers in Microbiology
IntroductionBacteria of genus Aggregatibacter vary with respect to dependence on exogenous nicotinamide adenine dinucleotide (NAD). The genus is incompletely resolved, as 20% of deposited Aggregatibacter genome sequences do not belong to named species ...

Aggregatibacter actinomycetemcomitans LPS binds human interleukin-8

open access: yesJournal of Oral Microbiology, 2019
Various gram-negative species sequester host cytokines using outer membrane proteins or surface modulation by sulfated polysaccharides. An outer membrane lipoprotein (BilRI) of the periodontal pathogen Aggregatibacter actinomycetemcomitans binds several ...
