FIG 3.

Effects of the combination of peptide DJK-6 and meropenem on preformed biofilms of KpC strains 1450421 and 2144392. Biofilms were grown in a flow cell system. Treatments were applied to a 2-day-old biofilm for 24 h. After this time, bacteria were stained green with the all-bacteria stain Syto-9 and red with the dead-bacteria stain propidium iodide (merge shows as yellow to red) prior to confocal imaging. Each panel shows reconstructions from the top in the large panel and sides in the right and bottom panels (xy, yz, and xz dimensions).
