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.

233 nm far‐UV‐C radiation for biofilm inactivation

Photochemistry and Photobiology, EarlyView.
Based on tests to assess biofilm formation potential (crystal violet staining, color of colonies grown on Congo red agar and calcofluor agar), three bacterial genera/species/strains (Staphylococcus (S.) epidermidis, S. aureus, Pseudomonas (P.) aeruginosa) were selected for analysis of their biofilm matrix composition.

Aggregatibacter actinomycetemcomitans LPS binds human interleukin-8

Journal of Oral Microbiology, 2019
Various gram-negative species sequester host cytokines using outer membrane proteins or surface modulation by sulfated polysaccharides. An outer membrane lipoprotein (BilRI) of the periodontal pathogen Aggregatibacter actinomycetemcomitans binds several ...

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

Distribution of nicotinamide phosphoribosyltransferase in genus Aggregatibacter and description of Aggregatibacter animalimorsus sp. nov., Aggregatibacter holmi sp. nov., and Aggregatibacter valvarum sp. nov.

Frontiers in Microbiology
IntroductionBacteria of genus Aggregatibacter vary with respect to dependence on exogenous nicotinamide adenine dinucleotide (NAD). The genus is incompletely resolved, as 20% of deposited Aggregatibacter genome sequences do not belong to named species ...

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.
