Abstract

Introduction: Methicillin – resistant S.aureus (MRSA) hss been recognized as an important
pathogen in human diseases. Screening of health care workers allowed early detection of nasal
carriage of MRSA and prevention of subsequent transmission. The aim of this study was to
determine the frequency of nasal carriage of MRSA in Shariati hospital staff.
Methods: This cross – sectional study was carried out on 85 personals of Shariati hospital
in Bandar Abbas. Nasal swabs were cultured on Monitol – Salt Agar plates and incubate at
37ºC for 24-48 hours. S.aureus were determined by Gram staining, Coagulase and DNase
tests. MRSA strains were identified by plate agar dilution method. An oxacillin minimum
inhibitory concentration (MIC ≥ 4 μ/ml) was considered as methicillin resistant. Analysis of
the results was performed by SPSS 16 software.
Results: S.aureus strains were detected in 24 (%28.2) samples from which 4 cases (%16.6)
were MRSA. No association among age, sex, occupation and duration of working and nasal
carriage of S.aureus or MRSA was recognized. A significant association between carrier
state and wards of the hospital was observed.
Conclusion: Due to role of MRSA in nosocomial infections, detection and treatment of
nasal carriers is of great importance.
