Studies on Susceptibility of Nine Antifungal Agents Against Dematiaceous Fungi by NCCLS M38-P Method / 中华皮肤科杂志

ABSTRACT

Objectives To evaluate the application of M38-P method recommend by NCCLS to dematiaceous fungi, and detect the susceptibility of itraconazole, fluconazole, miconazole, econazole, flucytosine, clotrimazole, nystatin, amphotericin B and terbinafine against dematiaceous fungi. Methods Using M38-P method forty-five strains of dematiaceous fungi were studied, which included 2 strains of Bipolaris spp., 1 strain of Drechslera spp., 1 strain of Curvularia spp.,14 strains of C. carrionii, 8 strains of F. pedrosoi, 3 strains of F. compacta and 16 strains of P. verrucosa. The media containing the fungi in the concentrations of (0.4 ~ 5) ? 106 CFU/mL were incubated at 35℃ for 5 ~ 7 days. Results The tested dematiaceous fungi were highly susceptible to itraconazole and terbinafine. Some of them were resistant to itraconzole, fluconazole, flucytosine and amphotericin B. Conclusions The data suggest that M38-P standards could be applied as the susceptibility testing of dematiaceous fungi, and it is necessary to monitor the resistant strains in antifungal treatment.
