本文报告MBC、5-FC及两者并用抗某些致病性着色真菌试管内的实验研究。结果表明MBC对常见的病原性着色真菌5种13株均具较强的抗菌作用,MIC值为3.13～0.10μg/ml,其作用明显大于5-FC。MBC与5-FC并用对裴氏着色真菌有明显协同作用,两者并用时MIC值均有明显下降,FIC指数<0.5,同位幅射图亦显示有协同作用。 This article reports the MBC, 5-FC and their combination with some pathogenic fungi in vitro test tube. The results showed that MBC had strong antibacterial activity against 5 kinds of 13 strains of common pathogenic fungi. The MIC value was 3.13 ~ 0.10μg / ml, which was obviously higher than that of 5-FC. MBC and 5-FC combined with Pei’s colored fungi have a significant synergistic effect, both MIC values ​​were significantly decreased, FIC index <0.5, the same position radiograph also showed a synergistic effect.
