title: [Antifungal drug susceptibility of Candida causing oropharyngeal candidiasis in HIV infected patients].
abstract: Candidiasis are very usual infections of HIV infected patients. By medicine pressure, susceptibility to antifungal drugs decrease in some Candida strains. This study carded out in 1997 at hospital, aimed to identify the yeast species isolated from HIV infected patients with oropharyngeal candidiasis, test their susceptibility to antifungal drugs and a previous antifungal treatment impact. Thus, 60 patients yielded to questionnary were recruited. Isolated yeast colonies from buccal tract after culture on Sabouraud medium with chloramphenicol were identified with the API 20 C AUX (BioMérieux) system by assimilation of different sugars. Susceptibility was evaluated by ATB FUNGUS (BioMérieux) system. 55 from the 60 isolated yeasts were identified and among them C. albicans and C. tropicalis were the main species with 75% and 11,7% respectively rates. In HIV1 infected patients, all specieswere isolated and C. albicans predominated (80,4%) on the other hand, C. albicans and C. tropicalis were the only isolated yeasts from the HIV2 infected patients with 83,3% and 16,6% respectively rates. Susceptibility of C. albicans was 72,2% to nystatine, 58,3% to amphotericin B, 83,3% to flucytosin, 12,8% to miconazole, 8,5% to econazole and 10,6% to ketoconazole. Susceptibility of C. albicans to polyenes was modified by a previous antifungal treatment. This study indicated emergence of saprophytic yeasts of the buccal mucosa and seemed to be more fostered by HIV1 serotype than HIV2. So, C. albicans's susceptibility to polyenes decreased by untimely use of antifungal drugs and by controlling it one could improve the clinic conditions of HIV infected patients.
