Evaluation of Antibiotic Drug Synergisms Against Periodontal Aggregatibacter Actinomycetemcomitans
Objectives: Aggregatibacter actinomycetemcomitans is major putative bacterial pathogen in human periodontitis, particularly in aggressive periodontitis in younger-aged individuals. Systemic administration of certain antibiotics in combination have been demonstrated to exert synergistic …

Aggregatibacter actinomycetemcomitans serotypes in gingival crevicular fluid of mothers delivering preterm.
… this study was to determine if the prevalence of Aggregatibacter actinomycetemcomitans (Aa) serotypes in gingival crevicular fluid (GCF) stored for more than ten years could be used as microbial biomarkers to predict preterm delivery. The study samples included 185 samples from “preterm birth” and …
