Aggregatibacter Actinomycetemcomitans: Clinical Significance of a Pathobiont Subjected to Ample Changes in Classification and Nomenclature

Pathogens, 2019
Aggregatibacter actinomycetemcomitans is a Gram-negative bacterium that is part of the oral microbiota. The aggregative nature of this pathogen or pathobiont is crucial to its involvement in human disease.

Antibiotic susceptibility of Aggregatibacter actinomycetemcomitans JP2 in a biofilm

Journal of Oral Microbiology, 2013
Localized aggressive periodontitis (LAgP) is an inflammatory disease associated with specific bacteria, particularly Aggregatibacter actinomycetemcomitans, which can result in early tooth loss. The bacteria grow as a biofilm known as subgingival plaque. Treatment includes mechanical debridement of the biofilm, often associated with empirical antibiotic

Leukotoxicity of Aggregatibacter actinomycetemcomitans in generalized aggressive periodontitis in Brazilians and their family members

Journal of Applied Oral Science, 2013
OBJECTIVE: The purpose of this study was to examine the leukotoxin promoter types of Aggregatibacter actinomycetemcomitans clones in subjects with generalized aggressive periodontitis (GAgP) and in their family members (FM).

Periodontitis and rheumatoid arthritis—Global efforts to untangle two complex diseases

Periodontology 2000, EarlyView.
Abstract Understanding the impact of oral health on rheumatoid arthritis (RA) will inform how best to manage patients with both periodontitis and RA. This review seeks to provide an update on interventional and mechanistic investigations, including a brief summary of European Research programs investigating the link between periodontitis and RA.

Osteomyelitis of the mandible due to Aggregatibacter (Actinobacillus) actinomycetemcomitans

Indian Journal of Pathology and Microbiology, 2009
Aggregatibacter (Actinobacillus) actinomycetemcomitans is a capnoic gram negative coccobacilli known to produce juvenile periodontitis. This organism was isolated in pure culture from an unusual case of osteomyelitis of the mandible. The patient was treated with tetracycline, which is the drug of choice for A.

Etiology, pathogenesis and treatment of peri‐implantitis: A European perspective

Periodontology 2000, EarlyView.
Abstract Peri‐implantitis is a plaque‐associated pathological condition occurring in tissues around dental implants. It is characterized by inflammation in the peri‐implant mucosa and progressive loss of supporting bone. Over the last 30 years, peri‐implantitis has become a major disease burden in dentistry.

The role of acquired host immunity in periodontal diseases

Periodontology 2000, EarlyView.
Abstract The aim of this narrative review is to relate the contribution of European researchers to the complex topic of the host immune system in periodontal disease, focusing on acquired immunity. Other chapters in this volume will address the genetics and autoantibody responses and other forms of immunity to periodontal disease.

Identification of a glutathione transporter in A. actinomycetemcomitans

Microbiology Spectrum
Bacteria rely on extracellular chemical cues to sense their environment, interact with one another, and shape their chemical landscape. Understanding this biochemistry can help us elucidate the mechanisms by which bacterial interactions impact community ...

The oral microbiota and periodontal health in orthodontic patients

Periodontology 2000, EarlyView.
Abstract The oral microbiota develops within the first 2 years of childhood and becomes distinct from the parents by 4 years‐of‐age. The oral microbiota plays an important role in the overall health/symbiosis of the individual. Deviations from the state of symbiosis leads to dysbiosis and an increased risk of pathogenicity.

Aggregatibacter actinomycetemcomitans Leukotoxin (LtxA; Leukothera^®): Mechanisms of Action and Therapeutic Applications

Toxins, 2019
Aggregatibacter actinomycetemcomitans is an oral pathogen that produces the RTX toxin, leukotoxin (LtxA; Leukothera®). A. actinomycetemcomitans is strongly associated with the development of localized aggressive periodontitis.
