Distribution and drug resistance of common pathogenic bacteria in grass-roots hospitals from 2008 to 2009

OBJECTIVE To understand flora distribution and drug-resistance in common pathogenic bacteria in grass-roots hospitals and provide the reference for clinical treatment.METHODS The susceptibility test was performed by K-B methods.The susceptibility results were analyzed according to CLSI.RESULTS Of 588 isolates from 2008 to 2009,Gram positive coccus and Gram negative bacilli accounted for 23.5% and 76.5%,respectively.The methicillin resistant Staphylococcus aureus(MRSA) and methicillin resistant coagulase negative Staphylococcus(MRCNS) accounted for 37.5% and 77.6%,respectively.The detection rates of extended spectrum β-lactamases(ESBLs) producing Escherichia coli and Klebsiella were 65.2% and 54.5%,respectively.CONCLUSION The common pathogenic bacteria present the multi-drug resistance.The reasonable antibiotics should be applied to prevent the occurrence and spreading of resistant strains.
