摘要 随着糖皮质激素、免疫抑制剂和高效、广谱抗生素的广泛应用、器官移植、各种导管介入性治疗的开展以及肿瘤、艾滋病的出现,导致条件致病性真菌感染日益增多,使得由丝状真菌引起的条件致病菌感染的发病率逐年升高,促使研究人员不断探讨和完善有关丝状真菌的体外药敏试验方法,评估其临床价值。产孢丝状真菌体外药敏试验方法主要有M38-P方案、M38-A方案、Etest法、流式细胞仪活性染色检测的应用、MTT和XTT比色法等。NCCLS方案具有准确性强、重复性好的特点,但是,还不能将其作为常规实验室检查方法,体外抗真菌药敏实验结果与临床疗效的关系是复杂的,成功的临床治疗不仅取决于致病菌的敏感性,也取决于宿主的免疫机制、药物的分布、患者的依从性等诸因素,药敏实验的MIC值高不意味着治疗失败,同样,MIC值低也不表明临床治疗一定成功。
