Analysis on the Hospital Infections Due to Extended Spectrum Batalaclose-Producing Bacteria

Objective;To investigate the incidence rate and distributed condition of the hospital infections due to extended spectrum batalaclose(ESBLs)-producing bacteria and the antibiotic resistance characterisation of the bacteria in our hospital.Methods:The ESBLs-producing bacteria assays were perfoumed with double-disk synergy test and compunud piece type confirm test.The bactrea identification and drug sesitivity tests were performed weith france bioMerieux-API identification system and K-B method,respectively.Result:Among 480 strains gram-negative bacilli,135 strains were ESBLs-producig bacteria(28.13%).Escherichia coli and klebasiella pneumoniae accounted for 24.89% and 35.34% of the ESBLs-producing bacteria,respectively,The antibiotic resistance rate of ESBLs producign bacteria was significantly higher than the non-ESBLs-producing bacteria(P0.01).The resistance strains to imipenem were not detected.Conclusion:The ESBLs assay should routinely be done in the clinical laboratory bacteria identification,it s helpful to control the spread and epidemic of ESBLs-producing bacteria.Imipenen is first selected drug for treat ESBLs-producing bacteria infections.
