The purpose of this study was to evaluate the influence of preparations containing silver sulfathiazole, with or without cerium nitrate, on survival of Staphylococcus aureus. In the first step, sensitivity of the planctonic bacteria to the tested compounds was determined. Addition of cerium nitrate enhanced the antibacterial activity of silver sulfathiazole by 4 times, as evidenced by MIC and MBC values. For the estimation of antibacterial activity of the mentioned chemotherapeutic on attached bacteria in vitro model of an "infected wound" was applied. Sensitivity of bacteria attached to the dermis was lower than sensitivity of planctonic bacteria. Kinetics of the release of chemotherapeutic compounds incorporated into a collagen dressing was the most effective for the combination of silver sulfathiazole with cerium nitrate.
