Abstract:
OBJECTIVE To monitor the Enterobacter cloacae resistance in our hospital patients.METHODS Disk susceptibility tests were performed for detection of E.cloacae resistance to 10 antibiotics,Detection of(extended)-spectrum ?-lactamases and AmpC ?-lactamase was conducted by three-dimensional extract test.RESULTS Seventy four strains of E.cloacae were isolated from our hospital patients,its had high resistant rate to 9 antibiotics(from(40.5%) to 91.8%),Among 74 strains of E.cloacae,10 isolates(13.5%) were considered as AmpC enzyme producing,31 strains(41.89%) were ESBLs-producing,6 strains(8.1%) were producing both of them.Total detection of AmpC(?-lactamase),or the production of ESBLs,or both of them were 47 strains(63.5%).Only imipenem was effective for all E.cloacae.CONCLUSIONS For the serious infection induced by E.cloacae producing AmpC ?-lactamase or(ESBLs),imipenem is first choice of treatment.
