摘要
目的评价替加环素等14种抗菌药物对多重耐药细菌的体外抗菌活性。方法采用微量肉汤稀释法测定替加环素对临床分离的214株多重耐药细菌(MRSA、肠球菌属细菌、鲍曼不动杆菌、产ESBLs大肠埃希菌、产ESBLs肺炎克雷伯菌和肠杆菌属细菌)的MIC,并与其他13种抗菌药物进行比较。数据分析采用WHONET5.4软件。结果多重耐药的MRSA对替加环素、万古霉素和利奈唑胺的敏感性均为100%。多重耐药的肠球菌属(粪肠球菌和屎肠球菌)对替加环素和利奈唑胺的敏感率均为100%,万古霉素敏感率为93.1%,2株万古霉素耐药的多重耐药屎肠球菌对替加环素和利奈唑胺均呈敏感,MIC90值分别为0.064mg/L和1mg/L。37株多重耐药鲍曼不动杆菌对替加环素的敏感率为97.3%,MIC90值为2mg/L,其中16株耐美罗培南的鲍曼不动杆菌对替加环素的敏感率仍为100%,MIC90值为2mg/L。产ESBLs大肠埃希菌和肺炎克雷伯菌对替加环素和美罗培南的敏感率均为100%,但替加环素的MIC90值均高于美罗培南。多重耐药的肠杆菌属细菌(阴沟肠杆菌和产气肠杆菌)对替加环素的敏感率为86.5%,MIC90值为4mg/L。结论替加环素对多重耐药的常见需氧革兰阳性球菌和革兰阴性杆菌均有良好的体外抗菌活性。
