摘要
目的对北京儿童医院的头癣患者分离所得的182株犬小孢子菌进行抗真菌药敏试验条件的探索。方法对致病真菌进行取样、培养、鉴定、分离和纯化,经微量稀释法测定8种常见抗真菌药物的最小抑菌浓度,并对原药敏方案进行适当调整。结果受试菌株的接种浓度为1~3×104CFU/mL。除伊曲康唑、联苯苄唑、阿莫罗芬外,使用沙氏液体培养基测定的药物最小抑菌浓度均较使用RPM I-1640液体培养基时药物浓度明显升高。孵育温度为28℃,孵育时间为5 d。结论各种药物的最小抑菌浓度(m in im al inh ib itory concentration,M IC)之间的差异有统计学意义,M38-A方案有较好的重复性和稳定性,可作为一种较好的实验室方法被应用。
