Aggregatibacter actinomycetemcomitans - Techne
Aggregatibacter actinomycetemcomitans is a non-motile, rod-shaped, Gram-negative bacterium This bacterium is also a facultative anaerobe which can grow under aerobic or anaerobic conditions The 43Kbp genome is arranged in a circular configuration and contains up to 60 open reading frames The outer surface of the cell includes appendages
Aggregatibacter actinomycetemcomitans colonization and
Aggregatibacter actinomycetemcomitans, a microorganism as-sociated with aggressive periodontitis, can result in tooth loss and systemic complications The hyperleukotoxin-producing A actinomycetemcomitans strain demonstrates up-regulation of attachment genes, permitting it to attach better than the wild-
Virulence Mechanisms of Leukotoxin from Aggregatibacter
Aggregatibacter actinomycetemcomitans is a gram-negative bacterium th at is present in the oral cavity of a large proportion of the human popu lation (Zambon et al , 1983; Henderson et al , 2010) The bacterium is acquired through transmission from infected individuals and
Glycosylation of the Collagen Adhesin EmaA of Aggregatibacter
The human oropharyngeal pathogen Aggregatibacter actinomycetemcomitans synthesizes multiple adhesins, including the nonfimbrial extracellular matrix protein adhesin A (EmaA) EmaA monomers trimerize to form antennae-like structures on the surface of the bacterium, which are required for collagen binding Two forms

Adaptation by Ancient Horizontal Acquisition of Butyrate
Aggregatibacter actinomycetemcomitans(Aa) is a Gram-negative oral bacterium that colonizes tooth surfaces in both humans (7) and nonhuman primates (8) However, in humans Aa is also strongly associated with localized aggressive perio-dontitis (LAP) (9), and it is also a known pathogen in endocarditis, brain abscesses, and pneumonia (10)
An In Vitro Comparison of Antimicrobial Effects of Curcumin
Aggregatibacter actinomycetemcomitans is an immobile microaerophilic, facultative anaerobic, gram negative coccoid rod,3 strongly associated with pathogenesis of periodontal diseases, particularly aggressive generalized periodontitis 4 Some of this bacterium’s membranous pro - teins play an important role in attachment to and pen-
