A prospective study of Methicillin Resistant Staphylococcus aureus (MRSA) infections in patients with cardiac surgeries and its antimicrobial sensitivity pattern
Journal Title: IJSR-International Journal Of Scientific Research - Year 2016, Vol 5, Issue 11
Abstract
Aim: To determine the prevalence of Staphylococcus aureus and Methicillin resistant Staphylococcus aureus (MRSA) in patients following cardiac surgeries and its antimicrobial susceptibility pattern.Patients and Methods: Consecutive patients undergoing cardiac surgeries between June2014 and December 2015 have been included for study. Suspected sites of infection were cultured, processed and MRSA identification was done by using cefoxitin (30μg) disc.The antimicrobial susceptibility testing was done by modified Kirby- Bauer disc diffusion technique.Results: The prevalence of MRSA in our study was 16.67% .Isolation rate of MRSA was more in males (80%) than females(20%) with a male female ratio of 4:1.The least resistant antibiotics were vancomycin(0%),linezolid(0%),cefoperazone sulbactam(20%) and piperacillin tazobactam(20%) and the most resistant antibiotics were penicillin(100%),amoxycillin clavulanic acid(80%), cefotaxime(80%), gentamicin(60%) and ceftriaxone (60%). Conclusions: There is a need for continuous surveillance and monitoring for the frequency of MRSA, a super bug with its antimicrobial resistance patterns which may help in decreasing the prevalence of MRSA and antibiotic resistance.
