RESUMEN
OBJECTIVE To investigate the drug resistance of ESBLs-producing Escherichia coli and Klebsiella pneumoniae in local nosocomial infection,for guiding the clinical drug resistance. METHODS ATB analysis system was used for identification of bacteria,extra-susceptibility tests were detected by K-B method. RESULTS The isolation rate of ESBLs-producing E. coli and the K. pneumoniae was 29.9% and 30.8%,respectively. The drug susceptibility was indicated the resistance rate of ESBLs producing strains to antibacterial agents except imipenem was higher than that of non-ESBLs producing strains. CONCLUSIONS Detecting drug resistance of ESBLs producing strains is of important significance for guiding the clinical rational use of antibacterials and controling the epidemics.
