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, 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-
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
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
