ABSTRACT
To determine rate of nasal colonization in Patients suffering from bacteraemia caused by methicillin resistant Staphylococcus aureus. This descriptive cross sectional study was carried out in a tertiary care, University Teaching Hospital [Shaikh Zayed Hospital, Lahore] from October 2010 to August 2011. Nasal swabs were taken from patients suffering from MRSA bacteraemia and were plated on mannitol salt agar plates to isolate Staphylococcus aureus [S. aureus] which were then tested for oxacillin susceptibility. Nasal colonization was present in 52.5% of patients suffering from MRSA bacteraemia. Nasal colonization rates with MRSA were high among patients suffering from MRSA bacteraemia especially in those undergoing dialysis or surgical procedures. Therefore, screening and nasal decolonization should be practiced in hospitals
