PREVALENCE OF MRSA AND MSSA INFECTION IN DIABETIC FOOT ULCER
This study investigated the prevalence of methicillin-resistant lessThan i greaterThan Staphylococcus aureus lessThan /i greaterThan (MRSA) and methicillin sensitive lessThan i greaterThan Staphylococcus aureus lessThan /i greaterThan in infected diabetic foot ulcers of 100 patients. Pus samples were collected and they were cultured by using appropriated methods. The lessThan i greaterThan S. aureus lessThan /i greaterThan was the most common pathogen among the Gram-positive bacteria isolated from ulcers. Of the 65 lessThan i greaterThan Staphylococcus aureus lessThan /i greaterThan isolated, 50 (76.92%) were found to be Methicillin resistant (MRSA) and 15 (23.07%) were Methicillin sensitive (MSSA). Methicillin resistance lessThan i greaterThan Staphylococcus aureus lessThan /i greaterThan were tested for vancomycin resistance. It was concluded that patients with diabetes for long duration (more than 10-15 yrs) with high blood sugar level (350-450mg/dl) were predominantly affected and the foot ulcers were significantly higher in males (80%). The Methicillin resistance lessThan i greaterThan Staphylococcus aureus lessThan /i greaterThan (MRSA) was sensitive to vancomycin and lessThan i greaterThan lessThan /i greaterThan imipenem lessThan i greaterThan lessThan /i greaterThan antibiotics and lessThan i greaterThan lessThan /i greaterThan the minimum inhibitory concentration (MIC) of vancomycin for MRSA is 0.01mg concentration and MIC of methicillin for MSSA is 60 mg concentration.
