摘要: 目的 评价粘菌素对临床分离多药耐药鲍曼不动杆菌的抗菌活性。 方法 收集解放军总医院、北京医院、北京协和医院3 家医院分离的非重复分离鲍曼不动杆菌70 株, 采用琼脂稀释法测定粘菌素与其他12 种抗菌药物的最低抑菌浓度(MIC), 以CLSI 标准判断其敏感率。 结果 70 株鲍曼不动杆菌, 对青霉素类和头孢菌素类的耐药率为71.4 %~ 82.9 %, 对碳青霉烯类(美罗培南、亚胺培南 西司他丁)的耐药率为75.7 % ~77.1 %, 对氨基糖苷类(奈替米星、阿米卡星)的耐药率为71.4 % ~ 75.7 %, 对氟喹酮类的耐药率(环丙沙星、左氧氟沙星)为32.9 %~ 82.9 %。共筛选出多药耐药鲍曼不动杆菌55 株, 对粘菌素全部敏感,MIC50和MIC90均为1 μg mL。 结论 鲍曼不动杆菌对本研究的大多数抗菌药物耐药率较高, 粘菌素对于鲍曼不动杆菌有很高的抗菌活性。

Abstract: AIM: To investigate the antimicrobial activity of Colistin and other antibiotics against Acinetobacter baumannii. METHODS: The agar dilution method was used to determine the minimum inhibitory concentrations (MICs)of Colistin and other antibiotics against 70 Acinetobacter baumannii collected from PLA General Hospital, Peking Hospital and Beijing Union Hospital.The sensitive rate was judged by CLSI stan-dard. RESULTS: The resistant rates of 70 Acinetobacter baumannii to penicillins and cephalosporins, carbopenems (meropenem and imipenem cilastatin), aminoglycosides(netilmicin and amikacin), fluoroquinolones(ciprofloxacin and levofloxacin)were 71.4 %-82.9 %, 75.7 %-77.1 %, 71.4 %-75.7 %, 32.8 %-82.9 %.Fifty-five multidrug-resistant Acinetobacter baumannii were isolated.All Acinetobacter baumannii in the study were sensitive to Colistin, the MIC50 and MIC90 were both 1 μg mL. CONCLUSION: Acinetobacter baumannii in the study were resistant to many antibiotics including penicillins and cephalosporins, carbopenems, aminoglycosides.Colistin has good antimicrobial activity against Acinetobacter baumannii.
