Abstract:ObjectiveTo study the distribution and drugresistance of methicillinresistant Staphylococcus aureus (MRSA), so as to provide reference for rational use of antimicrobial agents in clinic.MethodsData of 756 Staphylococcus isolates from clinical samples in a hospital from May 2008 to May 2010 were analyzed retrospectively.ResultsOf all Staphylococcus, 584 (77.25%) were Staphylococcus aureus, 394 (67.47%) of which were MRSA.MRSA mainly came from respiratory tract (248 isolates, 62.94%) and wound (121 isolates, 30.71%), and were mainly from intensive care unit (ICU) (53.30%) and surgery patients (19.29%). MRSA were all sensitive to vancomycin, teicoplain, and linezolid, but resistant to the other commonly used antimicrobial agents,minimum inhibitory concentration of 5.33% of MRSA to vancomycin was 2 μg /mL.ConclusionMRSA are mainly isolated from respiratory tract and wound of ICU and surgery patients, infection and drug resistance is serious, and has multiple drug resistance ; detection and drug resistant surveillance of MRSA should be strengthened.
