Susceptibilities of Madurella mycetomatis against amphotericin B and itraconazole in vitro were determined by protocols based on NCCLS guidelines (visual reading) and a 2,3-bis (2-methoxy-4-nitro-5-sulfophenyl)-5-[(phenylamino) carbonyl]-2H-tetrazolium hydroxide (XTT) assay for fungal viability. The XTT assay was reproducible and sensitive for both antifungals. Itraconazole (MIC at which 50% of the isolates tested are inhibited [MIC(50)]) of 0.06 to 0.13 mg/liter) was superior to amphotericin B (MIC(50) of 0.5 to 1.0 mg/liter).
根据美国国家临床实验室标准委员会(NCCLS)指南的方案(目视读数)以及基于2,3-双(2-甲氧基-4-硝基-5-磺基苯基)-5-[(苯胺基)羰基]-2H-氢氧化四唑(XTT)的真菌活力测定法,测定了马杜拉足分支菌对两性霉素B和伊曲康唑的体外敏感性。XTT测定法对这两种抗真菌药物均具有可重复性和敏感性。伊曲康唑(抑制50%受试分离株的最低抑菌浓度[MIC(50)]为0.06至0.13毫克/升)优于两性霉素B(MIC(50)为0.5至1.0毫克/升)。
