| Research Abstract |
The effect of azithromycin (AZM) and erythromycin (EM), which were macrolides, on Porphyromonas gingivalis biofilms produced by both static and flow-cell model was evaluated, and was compared with it against other antibiotics. AZM inhibited significantly both two biofilms in comparison with the other medicines at sub-minimum inhibitory concentration. It was guessed that the mechanism influenced three-dimensional structure or the signal transmission in the biofilm, but not was bactericidal namely an antibacterial action. And it was shown that its effect caused by the anti-biofilm action of AZM.
