Abstract:
OBJECTIVE To investigate the rate of the clinical isolation of ESBLs positive Escherichia coli and the resistance in intensive care units(ICU).METHODS We isolated E.coli from 2003 to 2004 in our hospital ICU,phenotypic confirmatory test was applied to detect ESBLs.Bacterial drug susceptibility test was performed by standard Kirby-Bauer method.RESULTS The isolation rate of ESBLs positive E.coli was 74.36% in 2003 and 81.58% in 2004.ESBLs positive bacteria had high resistance to antibacterial drugs,but the resistance rate did not rise.ESBLs negative bacteria were more susceptible to antibacterial drugs(P=0.001);but ESBLs negative bacteria in 2004 had higher resistance than in 2003(?2=84.511,P=0.001).CONCLUSIONS It is very important for ICU to use ESBLs detection test in time,and antibacterial drugs in reason.
