Age-related prevalence and characteristics of Aggregatibacter actinomycetemcomitans in periodontitis patients living in Sweden

Journal of Oral Microbiology, 2017
Background: The presence of Aggregatibacter actinomycetemcomitans in patients with periodontitis has been extensively studied for decades. Objective: To study the prevalence of A.

Natural Therapeutic Agents’ Efficacy in Preventive Strategies against the Periodontal Pathogen Aggregatibacter actinomycetemcomitans: An In Vitro Study

Oral
Adolescent carriers of the Aggregatibacter actinomycetemcomitans JP2 genotype have an increased risk of developing periodontitis, due to the bacterium’s high leukotoxin (LtxA) production.

The JP2 genotype of Aggregatibacter actinomycetemcomitans and marginal periodontitis in the mixed dentition

Journal of Clinical Periodontology, 2016
AbstractAimTo perform a cross‐sectional study on the carrier frequency of JP2 and non‐JP2 genotypes of A. actinomycetemcomitans in Moroccan school children and relate the presence of these genotypes to the periodontal status in the mixed dentition.Material and MethodsA plaque sample from 513 children was analysed by PCR. JP2 genotype‐positive subjects (

Comparative genomic hybridization and transcriptome analysis with a pan‐genome microarray reveal distinctions between JP2 and non‐JP2 genotypes of Aggregatibacter actinomycetemcomitans

Molecular Oral Microbiology, 2012
SummaryIt was postulated that the highly virulent JP2 genotype of Aggregatibacter actinomycetemcomitans may possess a constellation of distinct virulence determinants not found in non‐JP2 genotypes. This study compared the genome content and the transcriptome of the serotype b JP2 genotype and the closely related serotype b non‐JP2 genotype of A ...

Effectiveness of Salivary Sampling for the Detection and Quantification of Aggregatibacter actinomycetemcomitans and its JP2 Genotype in Periodontitis Patients

Abstract Aim The objective of this study was to evaluate the use of unstimulated saliva in detecting Aggregatibacter actinomycetemcomitans and its JP2 genotype, and to compare the saliva, subgingival and mucosa membrane occurrence of this periopathogen in patients diagnosed with advanced periodontitis.
