ABSTRACT
Background/aim:
Dermatophytes are the causative agents of dermatophytosis, which is a common disease worldwide that affects the hair, skin, and nails. Dermatophytes comprise more than 40 species in 3 genera Microsporum, Trichophyton, and Epidermaphyton. In this study, we aimed to determine the effectiveness of seven antifungal agents amphotericin B, terbinafine, itraconazole, voriconazole, ketoconazole, miconazole, and fluconazole. Materials andmethods:
A sensitivity study was performed using a microdilution method in accordance with the CLSI M38-A2 standards using isolates of Trichophyton rubrum (n = 55), Microsporum canis (n = 9), and Trichophyton interdigitale (n = 2), which were identified by sequencing the internal transcribed spacer region of the rDNA.Results:
According to the results of antifungal sensitivity tests, the geometric mean (GM) minimum inhibitory concentration (MIC) against T. rubrum was 0.10 µg/mL for ketoconazole, 0.20 µg/mL for itraconazole, 0.07 µg/mL for miconazole, 0.48 µg/mL for fluconazole, 2.27 µg/mL for amphotericin B, 0.06 µg/mL for voriconazole, and 0.06 µg/mL for terbinafine.Conclusion:
The most effective antifungal drugs were voriconazole and terbinafine, both of which had a GM MIC of 0.06 µg/mL.
