Abstract excerpt

Staphylococcus aureus nasal carriage is a potential source of secondary infections in COVID-19 patients, yet it remains unclear whether SARS-CoV-2 infection favors colonization by more virulent or resistant strains. We analyzed 31 nasal S. aureus isolates from hospitalized COVID-19 patients to assess antimicrobial resistance, virulence gene content, and genetic diversity. Only two isolates (6.4%) were methicillin...
