Background: Staphylococcus aureus nasal carriage plays an important role in the epidemiology and pathogenesis of infections, and this status accounts for both community-acquired and nosocomial infections. Objectives: This study was conducted to determine the frequency of the nasal carriage of S. aureus in healthy medical students. Results: Out of the 200 nasal swabs obtained, the overall nasal carriage of S. aureus was 24.5% (49/200). The prevalences of the methicillin-susceptible and resistant Staphylococcus aureus nasal carriage were 20% (40/200) and 4.5% (9/200), respectively, while the antibiotic susceptibility tests revealed that all 49 S. aureus isolates were sensitive to mupirocin. Conclusions: Despite the higher frequency of S. aureus nasal carriage in the interns, compared to the first year students, the difference did not reach statistical significance. Therefore, attendance at medical centers cannot be considered a risk factor for increasing carriage.
