JP2 Genotype of Aggregatibacter actinomycetemcomitans in Caucasian Patients: A Presentation of Two Cases

Pathogens, 2020
Aggregatibacter actinomycetemcomitans is a key pathogen that has been associated with periodontal disease. Its most important virulence factor is a leukotoxin capable of inactivating immune cells. The JP2 genotype of Aggregatibacter actinomycetemcomitans

Prevalence and comparative analysis of the type IV secretion system in Aggregatibacter actinomycetemcomitan

Journal of Microbiology, Immunology and Infection, 2018
Backgroud/purpose: Aggregatibacter actinomycetemcomitans has emerged as one of the aetiological agents in periodontal disease. Although Type IV secretion systems (T4SSs) are widely distributed in many bacteria, the genetic features and distribution of ...

Aging and periodontitis increase brain dissemination of oral bacteria

Journal of Periodontology, EarlyView.
Abstract Background The microbiome is a dynamic system that changes throughout life. Studies have revealed the relationship between periodontal disease and the oral microbiota; however, the impact of periodontal disease on the expression of senescence markers and on the inflammaging of the oral and systemic microbiome remains unclear.

Periodontal Status of Type 1 Diabetes Mellitus and Healthy Pregnant Women: A Case–Control Pilot Study

International Journal of Dental Hygiene, EarlyView.
ABSTRACT Aims This cross‐sectional ‘case–control’ pilot study aimed to compare the size of periodontal wounds, periodontal status and total inflammatory burden between pregnant women with type 1 diabetes mellitus (T1DM) and non‐diabetic pregnant women. Methods Fifteen T1DM pregnant women and 15 healthy pregnant women were included. Clinical parameters (
