Paeonol, the active ingredient ofroot bark, is widely used in traditional Chinese medicine. Few studies have reported the antibacterial activity of paeonol against bacterial pathogens. In this study, the antibacterial and anti-biofilm performance of paeonol againstandwas investigated as well as its mechanisms of action. Paeonol effectively inhibited the growth ofandwith a minimum inhibitory concentration of 64 μg mland it was shown to disrupt the integrity of bacterial cell membranes, and alter cell morphology. Moreover, paeonol exhibited a potent inhibitory effect against adhesion and biofilm formation byand. In particular, paeonol efficiently compromised cells within biofilms, and dispersed mature biofilms. Therefore, the present study suggests that paeonol is a promising alternative antibacterial and anti-biofilm agent for combating infections caused by planktonic and biofilm cells ofand.
