Community-acquired methicillin-resistant Consecutive MRSA isolates recovered from Co-SMSI of patients admitted from March 2022 to January 2023 in a Brazilian teaching hospital were tested for antimicrobial resistance and characterized by their genotypic features. Identification was carried out by automated method and through MALDI-TOF MS. Antimicrobial susceptibility was tested by disk diffusion, broth microdilution and E-test strips for determination of the minimal inhibitory concentration (MIC) according to recommendations from the Brazilian Committee on Antimicrobial Susceptibility Testing (BrCAST) and European Committee on Antimicrobial Susceptibility Testing (EUCAST). Gene mecA characterization and Sccmec typing were performed by multiplex polymerase chain reaction (PCR) assay, and gene lukF detection by single PCR. Patients were prospectively followed up for two months, in order to determine their clinical characteristics and outcomes.Aim
