Abstract BACKGROUND: Staphylococcus aureus is the main cause of diabetic foot infection with the patient's endogenous flora as the principal source. Nasal carriage of S. aureus has been identified as an important risk factor for the acquisition of diabetic foot infections. OBJECTIVES: The study assessment the associations of S. aureus with methicillin resistant S. aureus were isolation from diabetic foot infection and nasal carriage of the same patients and their antibiotic susceptibility profile. METHODS: Diagnosis of S. aureus and methicillin resistant S. aureus were carried out by using standard procedures. Antibiotic sensitivity profiles were determent by breakpoint dilution method. RESULTS: Out of 222 S. aureus isolation, 139 (62.61\%) were isolated from the diabetic foot and 83 (37.39\%) from the nasal carriage. Seventy one (30.87\%) of the patients were S. aureus infection diabetic foot with nasal carriage. Among diabetic foot infection and nasal carriage patients, 40.85\% of S. aureus were considered as methicillin resistant S. aureus. Rifampicin (96.40\%) and Levofloxacin (91.44\%) were active against S. aureus. CONCLUSION: Patients at strong risk for methicillin resistant S. aureus nasal carriage and subsequent diabetic foot infection with high resistance to antibiotics. Copyright © 2012 Elsevier Ltd.
