Abstract:
OBJECTIVE To investigate the productive rate of AmpC ?-lactamases and ESBLs produced by the Gram-negative bacilli from the nosocomial infection in our hospital. METHODS AmpC ?-lactamases and ESBLs were detected by the improved cefotaxime and ceftriaxone three-dimensional test. RESULTS The productive rate of AmpC ?-lactamases was 16.00%.Among them,the productive rate of AmpC ?-lactamases was only 8.84%.The Enterobacter cloacae,Serratia marcescens and Enterobacter aerogenes were easy to produce the enzymes(36.00%,31.25% and 28.00%).The productive rate of AmpC ?-lactamases and ESBLs at the same time was 7.16%. CONCLUSIONS The productive rate of the enzymes by the Gram-negative bacilli from the nosocomial infection is rather high.
