ABSTRACT
Objective To investigate the distribution pattern and antimicrobial resistance of the clinical isolates of pathogen.Methods The identification and dug susceptibility tests of the isolates from 2013 to 2015 were performed by using VITEK2-compact system.The susceptibilities of isolates to antimicrobial agents were analyzed with WHONET 5.6 software.Results A Total of 2 991(90.4%) gram-negative bacteria and 317(9.6%) gram-positive bacteria were isolated.Among all of the isolates,the top three pathogens were Klebsiella pneumonia,followed by Pseudomonas aeruginosa and Acinetobacter baumannii.The detection rates of extended-spectrum beta-lactamase(ESBLs)-producing Escherichia coli were 40.4%,48.2% and 38.3% respectively in the three consecutive years,while the detection rates of the ESBLs-producing Klebsiella pneumonia were 16.9%,8.4% and 11.6% respectively.No Escherichia coli resistant to impenem were detected.The resistant rate to impenem of Klebsiella pneumonia was 1.6%.The detection rates of methicillin resistant Staphylococcus aureus(MRSA) and methicillin resistant coagulase-negative staphylococci(MRCNS) in the three years were 53.8%,54.3%,42.9% and 84.5%,82.7%,85.9% respectively.No Staphylococci isolates resistant to linezolid and tigecycline were found.Enterococcus isolates were sensitive to gentamicine,linezolid,tigecycline and vancomycin.Conclusion Carbapenems could remain the best antimicrobials against Enterobacteriaccae.Lnezolid and tigecycline could be effective antimicrobials against Staphylococci isolates.The detection rates of Klebsiella pneumonia and Acinetobacter baumannii increased year by year.The monitoring of drug resistance should be strengthened to control the emergence and spread of multidrug resistant pathogen.
