In-vitro activity of five antifungal agents against uncommon clinical isolates of Candida spp.

A broth microdilution method and an agar dilution method were used for testing fluconazole, itraconazole, ketoconazole, flucytosine and amphotericin B against 98 clinical isolates belonging to seven species of Candida. The approximate rank order of fluconazole MICs was Candida lusitaniae approximately Candida kefyr < Candida famata approximately Candida guilliermondii < Candida pelliculosa approximately C. lipolytica approximately Candida inconspicua. Candida lypolitica and C. pelliculosa were the species least susceptible to itraconazole and ketoconazole. Flucytosine MICs revealed the highest prevalence of resistant strains among C. lipolytica and C. lusitaniae. All isolates were susceptible to amphotericin B.
