Genomic integration and expression of the Aggregatibacter actinomycetemcomitans catalase gene in Aggregatibacter aphrophilus [PDF]

Archives of Oral Biology, 2018
To test the hypothesis that virulence genes of Aggregatibacter actinomycetemcomitans can be expressed and confer fitness advantages in the closely related Aggregatibacter aphrophilus.Clinical isolates of A. aphrophilus were screened for natural competence with marked genomic DNA from A. actinomycetemcomitans and A. aphrophilus.

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

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.

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 ...

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 ...
