    The purpose of this study was to compare the agar dilution and broth microdilution methods for determining the minimum inhibitory concentration (MIC) of fluconazole, itraconazole, ketoconazole, griseofulvin and terbinafine for 60 dermatophyte samples belonging to the species Trichophyton rubrum, Trichophyton mentagrophytes and Microsporum canis. The percentage agreement between the two methods, for all the isolates with < 2 dilutions that were tested was 91.6% for ketoconazole and griseofulvin, 88.3% for itraconazole, 81.6% for terbinafine and 73.3% for fluconazole. One hundred percent agreement was obtained for Trichophyton mentagrophytes isolates evaluated with ketoconazole and griseofulvin. Thus, until a reference method for testing the in vitro susceptibility of dermatophytes is standardized, the similarity of the results between the two methods means that the agar dilution method may be useful for susceptibility testing on these filamentous fungi.<br>O prop贸sito do presente trabalho foi comparar os m茅todos de dilui莽茫o em 谩gar e dilui莽茫o em caldo para a determina莽茫o de concentra莽茫o inibit贸ria m铆nima de fluconazol, itraconazol, cetoconazol, griseofulvina e terbinafina para 60 amostras de dermat贸fitos pertencentes 脿s esp茅cies, Trichophyton rubrum, Trichophyton. mentagrophytes e Microsporum canis. A porcentagem de acordo entre os dois m茅todos para todos os isolados testados considerando-se valores < 2 dilui莽玫es, foram de 91,6% para cetoconazol e para griseofulvina, de 88,3% para itraconazol, de 81,6% para terbinafina e de 73,3% para fluconazol. Uma concord芒ncia de 100% foi obtido para isolados de Trichophyton mentagrophytes avaliados com cetoconazol e griseofulvina. Desta forma, at茅 que um m茅todo de refer锚ncia seja padronizado para testar a suscetibilidade in vitro para os dermat贸fitos, os resultados semelhantes encontrados para os dois m茅todos fazem com que o m茅todo de dilui莽茫o em 谩gar possa ser 煤til no teste de suscetibilidade para estes fungos filamentosos
