Staphylococcus aureus nasal carriage, virulence traits, antibiotic resistance mechanisms, and genetic lineages in healthy humans in Spain, with detection of CC398 and CC97 strains.

Abstract excerpt

S. aureus nasal carriage was investigated in 278 healthy humans, determining the antibiotic resistance mechanisms, virulence traits, and genetic lineages of recovered isolates. Nasal samples were cultured in specific media for S. aureus and methicillin-resistant S. aureus (MRSA) recovery. S. aureus was detected in 53 of 278 nasal samples (19.1%): MRSA was found in one sample (0.4%) and methicillin-susceptible S....
