The nasal carriage of Staphylococcus aureus represents a considerable risk for both nosocomial and community infections. The objective of this work was to investigate the prevalence of nasal carriage of both methicilin-susceptible (MSSA) and methicillin-resistant S. aureus (MRSA) in health workers, to determine their association with epidemiological factors and their patterns of antimicrobial resistance. One hundred and fifty-two nasal samples were taken from personnel from two hospitals in the Bahía Blanca city (Argentina). The S. aureus isolates were identified by conventional methods and by the automated BD PhoenixTM 100 system. The prevalence of S. aureus nasal carriage was 32.2% and that of MRSA, 12.2%. The frequency of carrying deterin laboratory personnel was statistically significant (58.8%). The isolates were susceptible to trimethoprim-sulfamethoxazole, chloramphenicol, rifampin, fluoroquinolones and vancomycin. These data warn of the need to identify S. aureus carriers and implement strategies that control the potential spread of these microorganisms.
