Scanning Electron Microscopy (SEM) images of different biofilms formed by Candida species and Escherichia coli treated/untreated by Oleuropein: (A, C) C. albicans without treatment; (B, D) C. albicans treated by MIC/2 of oleuropein, showing decrease in density of biofilm and disintegration of yeast (horizontal arrows); (E) C. glabrata without treatment; (F) C. glabrata treated by MIC/2 of oleuropein, showing increase in cell volume and destruction of yeast surfaces (vertical arrows); (G) E. coli without treatment; (H) E. coli treated by MIC/2 of oleuropein, showing decrease in cell aggregation and destruction of bacteria cell wall (arrows). (I) mixed biofilm of C. albicans and E. coli without treatment; (J) mixed biofilm of C. albicans and E. coli treated by MIC/2 of oleuropein showing destruction of yeast and E. coli (arrows)
