Abstract:
The present study was designed to obtain omparative data on in vitro antifungal activities of imidazole derivatives. Minimum inhibitory oncentrations of clotrimazole, miconazole, econazole, ketoconazlole and griseofulvin on 4 strains of Trichophyton mentagrophytes, 3 strains of Trichophyton rubrum, 2 strains of Microsporum canis and ] strain of Sporothriv: schenckii were etermined after 3 week' incubation at room temperature on Sabouraud's dextrose liquid media. In addition, the fungicidal activities of miconazole and econazole were tested against Z'richophyton mentagrophytes and Microsporum canis, using the techniques described by Vanbreuseghern(1967) The results are summarzed as follows: ] In most of the dermatophytes studied, 1 to 10 pg/ml of M1C were detected. Diverse susceptibility pattern was observed among different fungal species, but no or minor variability was noted within the same species. The susceptibility of Z'ri- chophyton rubrum showed at MIC of 0. 01 to 10 pg/ml, T ichophyton mentagro- phyt.es and Mic osporum canis at 0.1 to 10 pg/ml and 0. 1 to 1000 gg/ml respec- tively. The Trichophyton rubrum was the most sensitive. In the susceptibility test of Sporothrix schenckii, the high resistance to clotrimazole and griseofuhin was observed. The fungistatic activities of miconazole, econazole and ketoconazole were observed only at concentrations higher than JpQ pg/ml.
