Abstract:
OBJECTIVE To study the resistance of Acinetobacter baumannii in our hospital and the relation with ADC ?-lactmases.METHODS Antibiotic susceptibility testing was determined by K-B methods to 115 A.baumannii strains,and three dimensional extract testing was performed to detect the ADC ?-lactmases-producing strains,blaADC gene was detected by PCR methods,and the MIC of ceftazidime,et al were determined in the presence of cloxacillin(500 mg/L) in 30 A.baumannii strains detected.RESULTS The resistance to imipenem and cefoperazone/sulbactam was below 10.4%,to other antibiotic resistance was over 54%;the multiresistance strains were 59%.ADC ?-lactmases and blaADC genes were all positive and the MIC of ceftazidime,et al except cefepime was decreased over eight-fold in the presence of cloxacillin for multiresistant A.baumannii,but not for non-multiresistant A.baumannii.CONCLUSIONS The resistance of A.baumannii is very serious in our hospital,ADC ?-lactmases-producing strains are related markedly with the multiresistance of A.baumannii.
