The presence of infection in the wound delays the healing process. The main isolated micro-organisms are Staphylococcus aureus and Pseudomonas aeruginosa. Aim: To analyze the phenotypic and genotypic profile of Staphylococcus aureus strains in chronic lesions of outpatients treated with 2% hydrogel or polyurethane. Such analysis will support the decision with regard to the appropriate treatment and ensure greater speed in the tissue repair process. Method: this is a descriptive study that uses a quantitative approach. It is carried out through clinical specimen collection of lesions by swab, involving bacterial culture, identification and molecular characterization.
