Abstract：Objective:To investigate the distribution and drug resistance of clinical pathogenic bacteria in 2013 and provide bases for rational of antibiotics.Method:The bacterial indentification results of clinical specimens and the results of drug susceptibility testing performed in 2013 were statistically analyzed.Result:A total of 1374 strains of pathogens were isolated,including 401(29.2%) strains of gram-positive cocci,819(59.6%) strains of gram-negative bacilli,and 154(11.2%) strains of fungi. The Escherichia coli(345 strains),coagulase-negative Staphylococcus(183 strains),Staphylococcus aureus(156 strains), Klebsiella pneumoniae(138 strains),and Acinetobacter baumannii(81 strains) were the top 5 species of the isolated pathogens,accounting for 25.1%,13.3%, 11.4%,10.0%,5.9%.The resistance rates of Enterobacteriaceae against Carbapenem antibiotics,monobactams were less than 0.9%,but more than 78.6%about ampicillin.MRCNS accounted for 75.4%,MRSA accounted for 16.0%.Conclusion:The isolated pathogenic bacteria dominant in the Escherichia coli,which are mainly caused by the gram-negative bacilli.The MRCNS have a big portion in gram-positive cocci.The drug resistance of the isolated pathogenic bacteria is serious, the Susceptibility results should be performed in clinical practice so as to reasonably use antibiotics.
