<p>Biofilm bacteria counts of potential wound pathogens fell below the limit of detection within 48 hours for the AQUACEL® Ag+ dressing. Approximately an 8 log reduction (100 million-fold) reduction in biofilm bacteria was achieved for each challenge organism for the AQUACEL® Ag+ dressing. A >3 log reduction was achieved within 4 hours for S. aureus and P. aeruginosa biofilm bacteria. Three potential wound pathogens were shown to form dense biofilm on cotton gauze (S. aureus, P. aeruginosa and C. albicans). Biofilm forms of each potential pathogen were tolerant to two antimicrobial dressings (ionic silver and PHMB). Biofilm forms of each potential pathogen were highly susceptible to a new anti-biofilm Hydrofiber® dressing, AQUACEL® Ag+.</p>
