Abstract excerpt

Staphylococcus aureus (S. aureus) persistently colonizes the nares of approximately 20-30% of healthy individuals, and the nasal carriage constitutes a risk of infection and transmission. This pathogen causes mild to severe infections, different strains show variable virulence, and methicillin-resistant S. aureus (MRSA) is a global concern. Due to the worldwide aging of the population, further research in older...
