摘要:

目的 应用棋盘法测定以及探究粗糠柴苦素在体外联合氟康唑抗隐球菌是否有增效作用。方法 参照微量稀释法(M27-A3)对隐球菌进行氟康唑、粗糠柴苦素单药药敏实验[FLZ,RAT],以及以分数抑菌浓度指数(FICI)为判定指标棋盘法联合药敏实验[FLZ,RAT]。结果 粗糠柴苦素对37株隐球菌MIC值范围为32~256 μg/mL,在与氟康唑联合作用时,FICI均≤ 0.50,使氟康唑的MIC值降低了50%~93.75%。结论 粗糠柴苦素对隐球菌具有一定的抗真菌作用,同时与氟康唑联合使用能够发挥协同作用,提高氟康唑对隐球菌的敏感性。

Abstract:

Objective To determine whether there is synergistic effect of rattlerin combined with fluconazole against Cryptococcus in vitro by the checkerboard method. Methods According to the microdilution method (M27-A3), the fluconazole and rattlerin single drug susceptibility test[FLZ, RAT] and the Fractional Inhibitory Concentration Index (FICI) were used as the judgment indicators of combined drug susceptibility test[FLZ, RAT]. Results The MIC values of rattlerin to 37 strains of Cryptococcus were 32-256 μg/mL. When combined with fluconazole, FICI was ≤ 0.50, which reduced the MIC value of fluconazole by 2-16 times. Conclusion Rattlerin had a certain antifungal effect on Cryptococcus, and it could synergize with fluconazole to improve the sensitivity of fluconazole to Cryptococcus.
