Prevalence and antimicrobial susceptibility pattern of methicillin resistant staphylococcus aureus in central India
Journal Title: MedPulse -International Medical Journal - Year 2015, Vol 2, Issue 1
Abstract
Introduction: Methicillin resistant Staphylococcus aureus (MRSA) is an important nosocomial pathogen. The study reports the prevalence and antibiotic susceptibility pattern of MRSA in central india. Material and Methods: A total of 1690 clinical specimens were collected from different centers and subjected to MRSA screening using conventional microbiological methods. Subsequently the antibiotic sensitivity test was performed for the confirmed MRSA isolates. Results: Out of 210 strains of S. aureus isolated from clinical samples, 70 (33.33%) were found to be methicillin resistant respectively. Amongst all MRSA, 70 (100%) were resistant to penicillin, oxacillin, and gentamicin followed by amikacin (71.42%) and erythromycin(57.14%). MRSA also showed resistance to netillin, cotrimoxazole in 25.71% and 21.42% respectively. 14.28% resistance was also shown to chloramphenicol, ciprofloxacin and tetracycline, whereas all strains were sensitive to teicoplanin,vancomycin and linezolid. Conclusion: Routine screening of MRSA should be carried out by clinical microbiology laboratories because of the ability of these pathogens to acquire resistance to new classes of antimicrobial agents. Hence, surveillance on the antimicrobial susceptibility patterns is of utmost importance in understanding new and emerging resistance trends.
