Abstract |
During the 6 months between October 2003 and March 2004, we examined the frequency of isolation and susceptibility of Candida species isolated from various specimens at 6 facilities in Yamanashi. Sample numbered 9,083, and Candida species was predominantly isolated from 666 isolates (7.3%). 426 strains (64.0%) and 233 strains (35.0%) were Candida albicans and non-albicans Candida species (Candida species except C. albicans), respectively. Among the non-albicans Candida species, the frequency of isolation of Candida glabrata was the highest, followed by Candida tropicalis. Regarding the susceptibility of 659 strains of Candida isolated to antifungal agents, 1 mg/ml of amphotericin B inhibited growth of all strains excluding 1 strain of C. tropicalis. No fluconazole-resistant C. albicans was isolated, but MIC for the non-albicans Candida species distributed from ≤ 0.13 to ≥ 64 μ g/ml, showing the presence of low-susceptible and resistant strains. MIC of micafungin was 0.13 μ g/ml for C. albicans, C. glabrata, and C. tropicalis, and 0.5 μ g/ml for Candida krusei. The MIC90 of amphotericin B, fluconazole and micafungin against all Candida species tested were 0.25 μ g/ml, 4 μ g/ml and 0.06 μ g/ml, respectively. These findings may contribute to the treatment of deep mycosis. |
