The aim of this study was to investigate the susceptibility to four antifungal agents: ketoconazole, terbinafine, itraconazole and fluconazole, of the different species of dermatophyte strains isolated from clinical specimens. A total of 128 specimens were collected from toe nail, foot, inguinal region, trunk, hands and head. The dermatophytes tested included Trichophyton rubrum 108 (84.4%), Trichophyton mentagrophytes 11 (8.6%), Epidermophyton floccosum 5 (3.9%), Microsporum canis 2 (1.5%) and Trichophyton tonsurans 2 (1.5%). The mean minimum inhibitory concentrations (MIC) for the five species of dermatophytes ranged between 0.09-1.12 microg/mL for ketoconazole, 0.04-0.27 microg/mL for terbinafine, 0.08-0.43 microg/mL for itraconazole and 16.18-24.0 microg/mL for fluconazole. In vitro analysis of antifungal activity of these agents would also allow for the comparison between different systemic antifungals, which in turn may clarify the reasons for the lack of clinical response or serve as an effective therapy for patients with chronic infection.
