Abstract

|
Background: The emergence and spread of antimicrobial resistant bacteria is one of the reason why the vicious
failure of treatments and development of new antimicrobial agents continue. The prevalence of resistance bacteria differs in every country and region, therefore fundamental research in the rate of resistance bacteria is important. The goal of this study was to analyse the antimicrobial resistance rate of the bacteria isolated from Daegu Catholic Medical Center (DCMC).
Material and Methods: During recent 5 years (from 2004 to 2008), antimicrobial resistance rates of clinically important bacteria were researched through results which was cultured from clinical laboratory in DCMC .
Results: The rates of methicillin resistant Staphylococcus aureus (MRSA) was 81% at 2005, 70% at 2008. No vancomycin resistant strains was found in S. aureus and CNS. Vancomycin resistant enterococci (VRE) rate for E. faecalis was 22% at 2005, 1% at 2008, whereas for E. faecium was 38% at 2005, 6% at 2008. Imipenem resistance in P. aeruginosa, was average 48.8%, and for E. coli and K. pneumonia, was average 6.6% and 4.2%, respectively during recent 5 years.
Conclusion:< Antimicrobial resistance should be regarded as major concern in DCMC and it is urgently required to supervise the use of the antimicrobials and management of infection control. However fortunately, by comparing years of 2007 and 2008 to years of 2004 and 2005, most of the resistance rates appeared to show slight decrement.
