Radiographic and clinical signs of periodontitis and associated bacterial species in a Swedish adolescent population

Journal of Periodontology, Volume 94, Issue 5, Page 630-640, May 2023., 2023
Abstract Background Periodontitis in adolescents has historically been rare in the Nordic countries but could be expected to increase due to changing demographics. The primary aim was to cross‐sectionally examine the presence of radiographic bone loss in adolescents in Västerbotten County, Sweden.

Additional benefit of systemic antibiotics in subgingival instrumentation of stage III and IV periodontitis with Aggregatibacter actinomycetemcomitans: A retrospective analysis

Journal of Clinical Periodontology, Volume 50, Issue 5, Page 684-693, May 2023., 2023
Abstract Aim To evaluate subgingival instrumentation (SI) in periodontitis stage III and IV, grade B and C with systemic antibiotics (AB) only after detection of Aggregatibacter actinomycetemcomitans. Materials and Methods Patients of the Department of Periodontology of Goethe University Frankfurt/Germany were screened for microbiological testing ...

Molecular epidemiology of the citrus bacterial pathogen Xanthomonas citri pv. citri from the Arabian Peninsula reveals a complex structure of specialist and generalist strains

Evolutionary Applications, Volume 15, Issue 9, Page 1423-1435, September 2022., 2022
Abstract Molecular epidemiology studies are essential to refine our understanding of migrations of phytopathogenic bacteria, the major determining factor in their emergence, and to understand the factors that shape their population structure. Microsatellite and minisatellite typing are useful techniques for deciphering the population structure of ...

A comparative study on periodontitis and periodontitis‐associated bacteria in Somali and non‐Somali children and adolescents living in Trollhättan, Sweden

European Journal of Oral Sciences, Volume 130, Issue 2, April 2022., 2022
Abstract The reported prevalence of periodontitis in children and adolescents varies considerably between populations globally. This cross‐sectional study compares clinical and microbiological findings on 83 Somali immigrants and 96 non‐Somali children aged 10–17 years old living in Trollhättan, Sweden. The clinical examination included registration of

An in vitro model for studies of attenuation of antibiotic‐inhibited growth of Aggregatibacter actinomycetemcomitans Y4 by polyamines

Molecular Oral Microbiology, Volume 36, Issue 6, Page 308-315, December 2021., 2021
Abstract Polyamines are ubiquitous polycationic molecules that are present in all prokaryotic and eukaryotic cells, and they serve as important modulators of cell growth, stress, and cell proliferation. Polyamines are present at high concentrations in the periodontal pocket and could potentially affect the stress response of periodontal bacteria to ...

Microbial transitions from health to disease

Periodontology 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

Vaccines, 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

Pathogens, 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.

Human‐geographic effects on variations in the population genetics of Sinotaia quadrata (Gastropoda: Viviparidae) that historically migrated from continental East Asia to Japan

Ecology and Evolution, Volume 10, Issue 15, Page 8055-8072, August 2020., 2020
We document the population history and genetic history of the common freshwater snail Sinotaia quadrata in Japan and continental East Asia. Natural migration in the ancient period and artificial introduction in the recent period suggest that the population distribution is affected by both the geohistory of East Asia and the history of human expansion ...

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.
