Abstract:
OBJECTIVE To investigate the distribution and drug resistance of nosocomial infection pathogens in ICU from 2005 to 2008.METHODS Antimicrobial susceptibility test of 850 clinical isolates were carried out by means of K-B method.RESULTS Among 850 isolates,Gram-negative bacilli,Gram-positive cocci and fungi accounted for 68.9%,15.8% and 15.3%,respectively.ESBLs-producing strains accounted for 50% and 55.4% in E.coli and Klebsiella spp.MRS was detected in 82.7% of Staphylococcus.Imipenem and meropenem were the most active agents against strains of Enterobacteriaceae,Acinetobacter spp and Pseudomonas aeruginosa.No VRE or VRS strains were detected.CONCLUSIONS Gram-negative bacilli are the most frequent organisms in ICU.It is necessary to conduct drug resistance supervision of nosocomial infection pathogens in ICU and take measures to control nosocomial infection spread.
