Abstract

abstract Background: Actinobacillus actinomycetemcomitans (A. actinomycetemcomitans) is Gram negative and a major bacterial agent associated with aggressive periodontitis in young adult, this bacteria was an important factor in pathogenesis of aggressive periodontitis. A. actinomycetemcomitans possesses fimbriae with an adhesin protein that was the first bacterial molecules to make physical contact with host. Purpose: The objective of this research was to analyzed the influence of A. actinomycetemcomitans fimbrial adhesin protein induction on MMP-8 activity. Methods: The research was an experimental laboratory study, the step in this study were isolation and identification A. actinomycetemcomitans, characterize A. actinomycetemcomitans adhesin and study the role of A. actinomycetemcomitans adhesin in Wistar rats. Results: The result of this research on the role of adhesin in Wistar rats after analysis with Analysis of Variance (ANOVA) showed significant differences in the control group with group induction with A. actinomycetemcomitans, A. actinomycetemcomitans plus adhesin and adhesin. MMP-8 activity increased with induction A. actinomycetemcomitans and 24 kDa A. actinomycetemcomitans adhesin. This fimbrial adhesin protein showed that A. actinomycetemcomitans has the ability to adhesion, colonization and invasion for host in aggressive periodontitis pathogenesis. Conclusion: A. actinomycetemcomitans fimbrial adhesin protein induction increasing MMP-8 activity for aggressive periodontitis pathogenesis.
