The objective of our study was to examine the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) among residents of nursing homes for the elderly of selected institutions in two Slovak regions compared to non-institutionalized volunteers of the same age, as well as young volunteers (20-24 years old). Nasal swabs from all participants (n = 424) were processed using standard methods for the isolation and identification of S. aureus and MRSA. Statistically significant differences were found between nursing home residents and young volunteers (12% vs. 1.5%; OR 8.85; 95% CI 2.087-37.706; p = 0.0007), as well as between non-institutionalized seniors and young volunteers (11% vs. 1.5%; OR 8; 95% CI 1.888-33.901; p = 0.005) in the prevalence of MRSA. Our results suggest that nursing home residency and older age could be a risk factor for the occurrence of high-risk MRSA strains.
