Colonization of methicillin resistant staphylococcus aureus (MRSA) strains in patients of internal ward in Imam Reza hospital in Bojnurd

The major problem of different wards of hospitals is Methicillin-resistant Staphylococcus aureus(MRSA). Regarding the global importance of this strain to create nosocomial infections, it is necessary to determine the rate of infection in different wards of hospitals. This study aimed to determine the prevalence of Methicillin-resistant Staphylococcus aureus colonization in patients admitted to the internal ward of Imam Reza hospital in Bojnurd. A cross-sectional study was conducted on a total of 150 patients for 4 months in the internal ward of Imam Reza hospital. Methicillin disk diffusion method was applied for detection of methicillin-resistant strains. Susceptibility of Methicillin-resistant strains to commonly used antibiotics was determined by disk diffusion method. From150 patients, 13 (8.7%) were nasal carrier of Staphylococcus aureus, and %10 of cases (76.9%) were resistant to Methicillin. Presence of nasal carriers, indicated presence of Methicillin resistant S. aureus in patients of Imam Reza hospital. Although the prevalence of Staphylococcus aureus was not significant, most of the isolates were MRSA that could potentially distribute widely.
