Effects of silver dressings on wound area and re-epithelialisation in biofilm infected wounds. (A to H) representative macroscopic images of murine wounds infected with P. aeruginosa (A–D) and S. aureus (E–H) biofilms following three days treatment with a non-antibacterial control dressing, Ag Oxysalts dressing, Ag¹⁺ dressing and Ag¹⁺  + EDTA/BC dressing. (I–L) Representative P. aeruginosa infected, haematoxylin and eosin-stained histological sections used to quantify wound area and reepithelialisation. Quantification of wound area (M, O) and percentage re- epithelialisation (N, P) of P. aeruginosa (M, N) and S. aureus (O, P) biofilm infected wounds (n = 12 per treatment group). Graphs show mean + /- standard error. * indicates p =  < 0.05; ** indicates p =  < 0.01. Macroscopic scale bar = 2.5 mm, histological scale bar = 500 µm.
