We tested the effects of various putative efflux pump inhibitors on colistin resistance in multidrug-resistant Gram-negative bacteria. Addition of 10 mg/liter cyanide 3-chlorophenylhydrazone (CCCP) to the test medium could significantly decrease the MICs of colistin-resistant strains. Time-kill assays showed CCCP could reverse colistin resistance and inhibit the regrowth of the resistant subpopulation, especially in Acinetobacter baumannii and Stenotrophomonas maltophilia These results suggest colistin resistance in Gram-negative bacteria can be suppressed and reversed by CCCP.
我们测试了多种假定的外排泵抑制剂对多重耐药革兰氏阴性菌中黏菌素耐药性的影响。向测试培养基中添加10毫克/升的氰化物3-氯苯腙(CCCP)可显著降低耐黏菌素菌株的最低抑菌浓度(MIC)。时间杀菌试验表明,CCCP可逆转黏菌素耐药性并抑制耐药亚群的再生长,尤其是在鲍曼不动杆菌和嗜麦芽窄食单胞菌中。这些结果表明,革兰氏阴性菌中的黏菌素耐药性可被CCCP抑制和逆转。
