Abstract :

Objective The objectives of this study were to investigate the antifungal susceptibility and genetic diversity of Candida albicans isolated from HIV.sup.+ patients with oropharyngeal candidiasis. A total of 50 C. albicans isolates were cultured on Sabouraud glucose agar containing chloramophenicol. The antifungal susceptibility of the isolates against fluconazole, clotrimazole, nystatin, amphotericin B, ketoconazole and flucytosine was assessed using disc diffusion method. The genetic diversity of C. albicans isolates was determined using random amplified polymorphic DNA marker. Results The inhibition zones ranged from 4 [+ or -] 1.8 to 40 [+ or -] 3.8 mm for fluconazole, 7 [+ or -] 1.0 to 37 [+ or -] 1.8 mm for ketoconazole, 14 [+ or -] 0.8 to24 [+ or -] 0.8 mm for amphotericin B, 25 [+ or -] 0.0 to 33 [+ or -] 0.0 mm for nystatin and 7 [+ or -] 4.2 to 40 [+ or -] 0.0 mm for clotrimazole. At 90% similarity, three distinct groups were observed. The smallest cluster composed of 3 isolates, whereas the largest one composed of 17 isolates. 32% (16/50), 28% (14/50) and 14% (7/50) were resistant to fluconazole, ketoconazole and clotrimazole, respectively.
