The Microbial Aetiology of Periodontal Diseases [PDF]

open access: yes, 2012
Introduction: The study of the aetiology of periodontal diseases has continued for decades with much progress shown in the last two decades. Having moved through periods of “whole” plaque (with emphasis on mass) being attributed to the disease process,

Microbial transitions from health to disease

open access: yesPeriodontology 2000, Volume 86, Issue 1, Page 201-209, June 2021., 2021
Abstract Recent advances in our understanding of the microbial populations that colonize the human mouth, their acquisition, interdependency, and coevolution with the host, bring a different perspective to the mechanisms underpinning the maintenance of periodontal health and the development of disease.

Characterization of Aggregatibacter actinomycetemcomitans Serotype b Strains with Five Different, Including Two Novel, Leukotoxin Promoter Structures

open access: yesVaccines, 2020
The JP2 genotype of A. actinomycetemcomitans, serotype b has attracted much interest during the past three decades due to its close association with periodontitis in young individuals and the enhanced expression of a leukotoxin (LtxA).

Prevalence of Aggregatibacter actinomycetemcomitans and Periodontal Findings among 14 to 15-Year Old Danish Adolescents: A Descriptive Cross-Sectional Study

open access: yesPathogens, 2020
Aggregatibacter actinomycetemcomitans (Aa) is a keystone pathogen associated with periodontitis in adolescents. The knowledge on the prevalence of Aa and periodontitis among adolescents in Northern Europe is sparse.

Non-Surgical Therapy Reduces Presence of JP2 Clone in Localized Aggressive Periodontitis [PDF]

open access: yes, 2017
Previous studies have provided substantial evidence on the association of Aggregatibacter actinomycetemcomitans (Aa), and its highly leukotoxic JP2 genotype, with localized aggressive periodontitis (LAP).
