Determination of resistance patterns (by diffusion method) was performed according to the standard methods of methicillin. Results: Out of 63 participants, 8 subjects (12.7%) had colonization of S. aureus; 4 of them were physicians (17.3% of the participated physicians) and 4 were nurses (10% of the participated nurses). Out of 8 isolated SA, 2 cases (25%) and overall 3.1% were methicillin-resistant. In our study, there was a significant relationship between co-employment in other hospitals and patient care at home with SA colonization, but there was not a significant relationship with specialty, work experience, sinusitis, history of antibiotic use, history of skin disease, hand washing habits and use of personal protective equipment.
