ABSTRACT
The minimum inhibitory concentration (MIC) of nistatine, one of the most used antifungal agents for this micosis, was determined in 68 Candida strains isolated from vaginal smears. Candida albicans represented 75% of the total strains whereas C. parapsilosis, C. krusei and C. glabrata were much less frequently found. The predisposing factors were pregnancy and antibacterial treatment whereas leukorrhea and itching were the prevailing symptoms in most of the cases. MIC values from the use of a broth dilution method ranged from 0,5-8mg/mL and the geometric mean was 1.36mg/ mL. For C. albicans, MIC was 4mg/mL due to two strains that showed the highest MIC values (8 mg/mL). Similarly, the strains showed low MIC values, this means that therapeutic failures are not inherent to the emergence of resistant strains.
