Abstract

OBJECTIVE To perform a surveillance study in order to investigate the change in antimicrobial resistance of Klebsiella pneumoniae,especially extended-spectrum β-lactamases(ESBLs)-producing strains isolated.METHODS A total of 1986 strains of K.pneumoniae isolated during the last six years were analyzed.RESULTS Among 1986 K.pneumoniae strains,908(45.7%) were ESBLs-producing strains.The sensitive rate of ESBLs-producing K.pneumoniae to imipenem was 100%,and to meropenem was 99%.There were 636 strains isolated from ICU,accounted for 32%;and 480 strains isolated from Department of Respiratory Medicine,accounted for 24.2%.There were 1630 strains isolated from sputum,accounted for 82.1%.CONCLUSIONS K.pneumoniae is the major pathogen.Detecting ESBLs-producing strains rate and their susceptibility to antibiotics is very important in guiding the clinical administration of drugs.
