Discrepancies in Antimicrobial Susceptibility between the JP2 and the Non-JP2 Genotype of Aggregatibacter actinomycetemcomitans

Antibiotics, 2022
The Aggregatibacter actinomycetemcomitans JP2 genotype is associated with high leukotoxin production and severe (aggressive) periodontitis. The aim of this study was to compare the antimicrobial susceptibility of JP2 and non-JP2 genotype strains. Minimal

Aggregatibacter Actinomycetemcomitans: Current Overview

Dentistry and Oral Maxillofacial Surgery, 2022
Aggregatibacter Actinomycetemcomitans is one of the most aggressive pathobionts studied to the date. It encodes numerous putative toxins, the complex interplay of these toxins with the subgingival microbiota affects host defense mechanisms leading to rigorous destruction of the periodontium further causing loss of the tooth.

Anti-adherence potential of immunoglobulin Y Aggregatibacter actinomycetemcomitans against Aggregatibacter [PDF]

, 2020
Aggregatibacter actinomycetemcomitans is the main cause of aggressive periodontitis. Immunoglobulin Y (Ig Y) is the main antibody in poultry, reptiles, lungfish and can be found in chicken egg yolk.

Occurrence of Aggregatibacter actinomycetemcomitans in Brazilians with chronic periodontitis [PDF]

Brazilian Oral Research, 2010
Studies have suggested that A. actinomycetemcomitans is involved in the aetiology of aggressive periodontitis as well as in chronic periodontitis. This study was aimed at elucidating the occurrence of A. actinomycetemcomitans in a Brazilian population with chronic periodontitis. A total of 555 (mean age 33.04 +/- 12.45) individuals, living in two large

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 ...

Aggregatibacter actinomycetemcomitans Leukotoxin [PDF]

Journal of Dental Research, 2010
Aggregatibacter actinomycetemcomitans is a Gram-negative bacterium that colonizes the human oral cavity and is the causative agent for localized aggressive periodontitis (LAP), an aggressive form of periodontal disease that occurs in adolescents. A. actinomycetemcomitans secretes a protein toxin, leukotoxin (LtxA), which helps the bacterium evade the ...

Presence and Immunoreactivity of <i>Aggregatibacter actinomycetemcomitans</i> in Rheumatoid Arthritis. [PDF]

Pathogens
The presence of periodontal pathogens is associated with an increased prevalence of rheumatoid arthritis (RA). The systemic antibody response to epitopes of these bacteria is often used as a proxy to study correlations between bacteria and RA. The primary aim of the present study is to examine the correlation between the presence of Aggregatibacter ...
