The capacity of minocycline to enhance the activity of amphotericin B against Candida albicans, Torulopsis glabrata, Cryptococcus neoformans, and non-albicans Candida was examined in vitro utilizing a time-killing curve technique. Synergism was apparent at 4 h with 5 of 5 strains of C. albicans, 8 of 8 strains of C. neoformans, and 1 of 12 strains of non-albicans Candida. Synergism was apparent at 24 h with the remaining 11 strains of non-albicans Candida and all 5 strains of T. glabrata. C. neoformans was the most susceptible of the yeasts to the minocycline-amphotericin B combination; seven strains showed a 3-log or greater reduction in colony count in 4 h and all strains showed this reduction in 24 h at amphotericin B concentrations of 0.4 mug/ml or less in the presence of minocycline.
利用时间杀菌曲线技术在体外检测了米诺环素增强两性霉素B对白色念珠菌、光滑念珠菌、新型隐球菌和非白色念珠菌活性的能力。在4小时时,5株白色念珠菌中的5株、8株新型隐球菌中的8株以及12株非白色念珠菌中的1株出现协同作用。在24小时时,其余11株非白色念珠菌和所有5株光滑念珠菌出现协同作用。新型隐球菌是酵母中对米诺环素-两性霉素B组合最敏感的;在米诺环素存在的情况下,当两性霉素B浓度为0.4μg/ml或更低时,7株新型隐球菌在4小时内菌落计数减少3个对数或更多,所有菌株在24小时内均出现这种减少。
