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 ...

Biofilm-stimulated epithelium modulates the inflammatory responses in co-cultured immune cells [PDF]

, 2019
The gingival epithelium is a physical and immunological barrier to the microbiota of the oral cavity, which interact through soluble mediators with the immune cells that patrol the tissue at the gingival epithelium.

The aggregatibacter actinomycetemcomitans heat shock protein GroEL interacts directly with human peripheral blood T cells [PDF]

, 2016
Heat shock family protein GroEL of Aggregatibacter actinomycetemcomitans (Aa) has antigenic properties. We previously demonstrated that A. actinomycetemcomitans GroEL-like protein affects human CD4 T cells by converting them into IL-10 and IFNg double ...

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 ...

Periodontitis treatment and microbiome in a patient with FAM20A mutation: Case study of 1.5 years

Clinical Advances in Periodontics, EarlyView.
Abstract Background Enamel‐renal‐gingival syndrome (ERGS) is an autosomal recessive disorder caused by mutations in the FAMily with sequence similarity 20A (FAM20A) gene, and is characterized by amelogenesis imperfecta, delayed or failed tooth eruption, and periodontitis.
