Results: The MBCs of ethanol, glutaraldehyde disinfectant, ShiKang disinfectant and quaternary ammonium disinfectant against multidrug-resistant Acinetobacter baumannii were 45%, 10000 mg/L, 6.3~12.5 mg/L and 100 mg/L, and the MBCs were 40%, 5000 mg/L, 3.1~6.3 mg/L and 50 mg/L Conclusion: MBC and MIC could represent the sensitive dose of multidrug-resistant Acmetoborter baumannu to disinfectants, and eight strains of multidrug-resistant Acinetobacter baumannii have certain resistance to some common disinfectants.

结果：乙醇、戊二醛消毒液、施康消毒液、季铵盐消毒剂对多重耐药鲍曼不动杆菌的MBC值分别为45%、10000 mg/L、6.3~12.5 mg/L、100 mg/L；MIC值分别为40%、5000 mg/L、3.1~6.3 mg/L、50 mg/L、50 mg/L。结论：MBC值和MIC值能基本反应多重耐药鲍曼不动杆菌对消毒剂的敏感剂量，8株多重耐药鲍曼不动杆菌对部分消毒剂产生一定程度的耐药性。
