10.22376/ijpbs.2019.10.1.p1-12 Volume 6 Issue 3 2015 (July - September) The purpose of this study was to evaluate risk factors for lessThan i greaterThan M lessThan /i greaterThan lessThan i greaterThan ethicillin-resistant lessThan /i greaterThan lessThan i greaterThan Staphylococcus aureus lessThan /i greaterThan (MRSA) from nasal carriers in patients hospitalized for diabetic foot ulcer infections. The study material consisted of nasal swabs collected from diabetic foot ulcer patients admitted at Sri Lakshmi Narayana Institute of medical sciences during the period of 3 months from November 2014 to January 2015. All the samples were subjected to gram staining and bacterial culture and lessThan i greaterThan S. aureus lessThan /i greaterThan isolates were screened for MRSA prevalence using microbiological methods. All the clinical isolates are subjected to antimicrobial susceptibility testing on Mueller Hinton agar using the Kirby-Bauer disc diffusion method. lessThan i greaterThan S. aureus lessThan /i greaterThan was the most common pathogen among the Gram-positive bacteria isolated from nasal carriers of diabetic foot ulcer patients. Out of 100samples, 65 lessThan i greaterThan Staphylococcus aureus lessThan /i greaterThan was isolated, 40 (40%) were found to be lessThan i greaterThan Methicillin-resistant lessThan /i greaterThan lessThan i greaterThan Staphylococcus aureus lessThan /i greaterThan (MRSA) (MRSA) and 25 (25%) were found to be lessThan i greaterThan Methicillin sensitive lessThan /i greaterThan lessThan i greaterThan Staphylococcus aureus lessThan /i greaterThan (MSSA).Patients with diabetes with high blood sugar level (350-450mg/dl) were predominantly affected and the foot ulcers were significantly higher in males (70%). Identifying risk factors for MRSA infections could improve prevention and treatment in diabetic foot infections, reduce resistance patterns and reduce health care costs.
