Abstract

Currently, there has been an increased frequency of fungal infections. Candida albicans and other Candida spp. have been proven to be major causes for urinary tract infection. Increased resistance to antifungals indicates the need to develop strategies in order to prevent the spread of resistance. Chromogenic medium have been proven to be useful in the detection of yeasts in clinical specimens containing mixed cultures of Candida. The aim of this study was to compare the results of antifungal susceptibility testing with fluconazole and amphotericin B on strains of Candida spp. isolated from urine, conducted on a Mueller–Hinton Agar with Glucose and Methylene Blue (MHAGMB) medium and on a Hicrome Candida® Agar with 2% Glucose (HCAG) medium. We used 40 samples of Candida spp. isolated from urine samples from inpatients and outpatients. The results showed that both media presented high rates of agreement, above 94%. The use of the HCAG medium decreases the release time of the results by 24–48 h, which may be decisive for initiating the correct drug treatment.
