A comparison of the antimicrobial effects of four silver-containing dressings on three organisms

摘要: Objective: To compare the antimicrobial activity of four silver-containing dressings: Acticoat (Smith and Nephew), Actisorb Silver 220 (Johnson Johnson), Avance (SSL International) Contreet-H (Coloplast). Method: The dressings were tested against three micro-organisms: a Gram-positive bacterium, Staphylococcus aureus; Gram-negative organism, Escherichia coli; yeast, Candida albicans, using different techniques. Each dressing also had its silver content analysed. Results: is likely to produce most rapid effect in vitro because release relatively large concentrations highly active ions. has broadly similar Acticoat, but slower onset action. appears offer less prospect killing bacteria within wound itself, capable removing micro-organisms from exudate sequestering them until they are inactivated by charcoa...
