An Evaluation of the Antibacterial Properties of Tormentic Acid Congener and Extracts From Callistemon viminalis on Selected ESKAPE Pathogens and Effects on Biofilm Formation

Figure 6

The effect of ciprofloxacin, tormentic acid congener, and C. viminalis extracts on biofilm detachment in S. pyogenes (a) and A. baumannii (b). Ciprofloxacin showed less effect on preformed biofilms than C. viminalis extracts and tormentic acid congener. Tormentic acid congener caused detachment of biofilms in S. pyogenes more than other agents, whilst the EtOH extract of C. viminalis had the greatest effect in A. baumannii.
