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

<div>The effect of ciprofloxacin, tormentic acid congener, and C. viminalis extracts on S pyogenes (a) and A. baumannii (b) biofilm production, respectively. The bacterial strains were incubated together with the test agents for 72 hours, and the formed biofilm was quantified using 0.1% crystal violet. Ciprofloxacin inhibited the formation of biofilms in both bacteria, whilst tormentic acid congener and C. viminalis extracts showed no significant inhibitory effect. Asterisk denotes a significant difference (∗∗∗∗P &lt; 0.0001).</div>
