【摘要】 目的研究全耐药鲍氏不动杆菌相关耐药基因的流行情况。方法对临床分离的17株鲍氏不动杆菌进行菌株鉴定和药敏试验,并运用PCR方法检测相关耐药基因。结果17株鲍氏不动杆菌对医院检测的抗菌药物全部耐药;17株菌中TEM-1、OXA-23、OXA-27、gyrA和AmpC基因的检出率为100.0%,2株菌携带aacC1基因(11.8%),9株菌携带PER-1基因(52.9%)。结论医院鲍氏不动杆菌流行株主要携带TEM-1、OXA-23、OXA-27、gyrA、AmpC、aacC1和PER-1等多个耐药基因,基因型与表型基本一致,临床工作中医生应重视全耐药鲍氏不动杆菌的诊断与治疗,减少交叉感染的发生,加强医院感染的控制。更多还原

【Abstract】 OBJECTIVE To investigate the prevalence of drug-resistant genes in seventeen strains of all-resistant Acinetobacter baumannii.METHODS Microdilute tests were performed to detect the susceptibility of 17 A.baumannii strains to 16 kinds of antimicrobial agents and antimicrobial-resistant genes were detected by PCR methods.RESULTS Seventeen A.baumannii strains showed all-drug resistance.Genes of TEM-1,OXA-23,OXA-27,gyrA and AmpC were detected in all 17 strains of A.baumannii.The positive rates of aacC31 and PER-1 genes were 11.8% and 52.9%,respectively.CONCLUSIONS A.baumannii with multi-resistant genes of our hospital carries TEM-1,OXA-23,OXA-27,gyrA,AmpC,aacC1 and PER-1.更多还原
