• Infection and the formation of biofilms have been shown to have a significant role in increased inflammation and delayed wound healing. Wound irrigation solutions are used to debride wounds, removing cell debris and infecting microorganisms, therefore preventing infection. The aim of this study was to evaluate a Polihexanide (PHMB) based wound irrigation solution, Octenidine HCl based wound irrigation solution and electrolysed water based wound care solution for antibiofilm efficacy against Staphylococcus aureus, Pseudomonas aeruginosa and a multispecies biofilm in several models to gain a broad understanding of ability. The PHMB based wound irrigation solution demonstrated broad range antibiofilm efficacy against P. aeruginosa, S. aureus and the multispecies biofilm. The Octenidine HCl based wound irrigation solution and the electrolysed water based wound care solution demonstrated potent antibiofilm efficacy against S. aureus and to a lesser extent P. aeruginosa. Overall, less efficacy was observed in the drip flow bioreactor model for all 3 test solutions, which may be attributed to the continuous flow of nutrients during treatment, which may have diluted or washed away the solution. The data presented also highlights the importance of testing antibiofilm activity in a range of biofilm models and against different bacterial strains to get an overall representation of efficacy.
