Nasal and extra nasal MRSA colonization in hemodialysis patients of north-west of Iran.

Overall, 50.65% (118/231) hemodialysis patients were positive for S. aureus which 34.93% (80/231) of patients were MRSA carriage. The MRSA colonization in patients with a catheter (44.06%) was more than individuals utilizing a fistula (24.57%, p = 0.030). Among sampling sites, the highest MRSA was related to nasal samples (30.70%, p < 0.00001). Extra nasal colonization of S. aureus was observed in 12.71% patients. The highest rates of resistance were observed against ampicillin (93.98%) and the highest sensitivity was against linezolid antibiotic (5.42%). These findings highlight the necessity of prophylaxis against S. aureus in individuals under dialysis.
