Study of adhesin from Aggregatibacter actinomycetemcomitans local isolate on alveolar bone destruction in aggressive periodontitis disease
Aggregatibacter actimycetemcomitans produces several virulence factors involved in the colonization of the oral cavity, destruction and inhibition of regeneration of the periodontal tissues and evasion of host defense mechanisms. Bacterial adhesin is a medium for bacteria to invade the host. Ligand...

First, the adhesin of A. actinomycetemcomitan with a molecular weight (MW) of 24 kDa was induced to Wistar rats.
