Gray scale analysis of the sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) with Image J. (compared with no antibiotic treatment, * p < 0.05, one-way analysis of variance (ANOVA) followed by Least Significant Difference (LSD) post hoc comparison.). CI= clinical isolate, MIC = minimum inhibitory concentration.
