ABSTRACT
OBJECTIVE:To study the?-lactamase production in multi-drug resistant acinetobacter baumannii isolated in clinic.METHODS:Susceptivity to antibiotics of the bacteria was measured by K-B and agar diffusion methods.The?-lac-tamase production of acinetobacter baumannii was examined by nitrocefin disc test,then their plasmid and chromosome ex-tracted as templete,the genes coded the?-lactamase were amplified by PCR with commercial kits.Furthermore,the sequence and homology of PCR products were analyzed.RESULTS:Total12acinetobacter baumannii in this study were?-lacta-mases-producing strains with a high resistance to cephalosporin.However,it is sensitive to carbapenem-antibiotics and cephalosporin with?-lactamase inhibitors,and6strains of them were confirmed that there were?-lactamases AmpC gene on plasmid by PCR amplification and sequence analysis.CONCLUSIONS:The?-lactamases AmpC mediated by plasmid would be main factor in the high resistance to cephalosporin of acinetobacter baumannii isolated clinically.
