[Evaluation of susceptibility of dermatophytes to antifungal drugs].

A serial dilution and a disc method were used for evaluation of susceptibility of 50 dermatophyte strains belonging to the species Trichophyton rubrum, Trichophyton mentagrophytes, Microsporum canis and Epidermophyton floccosum. Following drugs were investigated: griseofulvin, pimaricin, clotrimoxazole, miconazole, ketoconazole, biphonazole and naftifin. Application of two methods of testing resulted in high convergence of determinations. Naftifin was most effective and pimaricin least active. Among imidazole drugs, relatively high activity against dermatophytes was exhibited by clotrimoxazole and ketoconazole. Strain of Trichophyton rubrum were more susceptible to antifungal drugs than strains of Trichophyton mentagrophytes.
