Klebsiella pneumoniae Planktonic and Biofilm Reduction by Different Plant Extracts: In Vitro Study

Figure 2

Application of glycolic extracts of R. officinalis, P paniculata, and J. regia at concentration of 200 mg/mL against K. pneumoniae biofilm during 5 min. Control group received 0.9% NaCl during 5 min. The results indicate the mean values of cell viability reduction in percentage of each extract compared to the control group. Letters (A or B) express the comparison of groups in statistical analysis ().
