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

Figure 1

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