Molecular epidemiology, antimicrobial resistance, and virulence characteristics of predominant methicillin-resistant Staphylococcus aureus clones with strong biofilm-producing capability from a tertiary teaching hospital in China

This is the first report of the phenotypic-genotypic characteristics of MRSA with both strong biofilm-producing and virulence potential, with ST5-t2460, ST59-t437, and ST239-t030 clones accounting for the major genotypes. Further exploration of specific virulence genes correlating to the pathogenesis of this superbug is deemed essential for developing targeted infection control and treatment strategies in the future.
