METHODS The species of the kinds of microorganisms isolated during year 2012 and their antibacterial-resistance were analyzed by software WHONET5.4. RESULTS A total of 2494 clinical isolates of non-repeated bacteria were isolated, including 1504(60.3%) strains of gram-negative bacteria , 917(36.77%) strains of gram-positive bacteria, and 73(2.92%) strains of fungi. The positive rates of ESBLs-producing Esche-richia coli and Klebsiella were 56.32%、14.35%. The positive rates of ESBLs-producing Klebsiella was lower than reported in china（＞50%）. Rate of Methicillin-resistant Staphylococcus aureus(MRSA) was 24(10.13%)strains, lower than reported in china（＞50%）. Rate of Methicillin-resistant S. epidermidisaureus was 87(71.54%)strains. CONCLUTION Due to the large variety of bacterial resistance varies, so it is necessary to strengthen bacterial culture. reasonably select the antibiotics based on the drug susceptibility testing, so as
