Visualisation of in vivo wound biofilms after 3 days treatment with control or silver dressings. Confocal images of P. aeruginosa (A–D) and S. aureus (I–L) stained with Toto 1 (green) to visualise the extracellular nucleic acids, a component of the biofilm’s extracellular polymeric substance, and Syto 60 (red) which stains intracellular nucleic acids. P. Scanning electron microscopy of P. aeruginosa (E–H) & S. aureus (M–P) biofilm infected wounds after 3 days treatment with control and silver dressings. SEM scale bars = 5 µm. Confocal imaging scale bars = 50 µm.
