Abstract:
OBJECTIVE To investigate the genes of AmpC and ?-lactamases and antibiotic resistance of A.baumannii strains in elderly.METHODS The sensitivity to 13 kinds antibacterials was analyzed according to CLSI 2005′s Standard.The genes of AmpC and ?-lactamases were detected by polymerase chain reaction(PCR).RESULTS Most of the strains were A.baumannii.In 20 strains of A.baumannii,the positive strains of AmpC(chromosome) were 17(85%),that of TEM and PER 5 strains were 11 strains(55%) and 25%,respectively.CONCLUSIONS High positive percentages of AmpC(chromosome),TEM and PER genes in A.baumannii strains isolated from elderly are found.
