From: Hypertonic saline enhances the efficacy of aerosolized gentamicin against Pseudomonas aeruginosa
3-D images of colony microstructure and distribution of live and dead bacteria on the biofilm structure after aerosol treatments. Live cells are pseudo-colored green, and dead cells are pseudo-colored red. (a) Overnight growth of the Pseudomonas aeruginosa (PAO1 strain) colony. (b) The colony treated with the saline-gentamicin aerosol. (c) Cells showed patch-like structures after hypertonic saline aerosol treatment. (d) Distinct holes in the colony after hypertonic saline-gentamicin aerosol treatment. (e) Optical section of the colony treated with the hypertonic saline-gentamicin aerosol. (Scale bar: 50 µm).
