Abstract

We carried out performance evaluation tests using clinical isolates in a modified yeast fungal drug susceptibility test kit ASTY plus caspofungin (CPFG) (Kyokuto Pharmaceutical Industry Co., Ltd., Tokyo, Japan). We used 51 strains of clinical isolates (Candida albicans, 30 strains; C. dubliniensis, 2 strains; C. glabrata, 4 strains; C. tropicalis, 4 strains; C. guilliermondii, 4 strains; C. parapsilosis, 4 strains; C. krusei, 3 strains). In this evaluation, minimum inhibitory concentration values of clinical isolates using the control CLSI method (Yeast-like fungi FP; Eiken Chemical, Tokyo, Japan), ASTY method, and another method (Yeast-like fungus DP; Eiken Chemical) were compared. The drugs with a concordance rate of 90% or more within ±1 tube were CPFG, amphotericin-B, 5-flucytosine, voriconazole, and those with a concordance rate of 80% or more were micafungin, fluconazole, and itraconazole. The above results clarified that the ASTY method correlated highly with the CLSI method.

用含Caspofungin的快速比色微稀释法评价念珠菌的敏感性。

我们使用改良酵母真菌药敏试验试剂盒(ASTY + caspofungin, CPFG) (Kyokuto Pharmaceutical Industry Co.， Ltd, Tokyo, Japan)对临床分离株进行了性能评价试验。临床分离51株(白色念珠菌30株;dubliniensis, 2株;光斑草，4株;热带锥虫4株;吉列蒙地菌，4株;副枯枝孢菌4株;克鲁氏弧菌，3株)。在本评价中，使用对照CLSI方法分离的临床分离物的最小抑菌浓度值(酵母样真菌FP;Eiken Chemical, Tokyo, Japan)， ASTY法和另一种方法(酵母样真菌DP;艾肯化学公司)进行比较。±1管内符合率≥90%的药物为CPFG、两性霉素- b、5-氟胞嘧啶、伏立康唑，符合率≥80%的药物为米卡芬金、氟康唑、伊曲康唑。以上结果表明，ASTY方法与CLSI方法具有较高的相关性。
