Abstract :
Ovington (2004) suggests that all silver dressings work only via Ag+; however, there is evidence that nanocrystalline silver, which is highly effective against fungi, bacteria, and antibiotic resistant bacteria, releases unique species of silver in addition to Ag+, such as Ag0 clusters. In this study, the efficacy of three silver dressings, two that generate only Ag+ and one that releases multiple species of silver including Ag+ and Ag0, against silver sensitive and resistant strains of P. aeniginosa were compared to determine if there is an advantage to multiple-species releasing dressings.
