Abstract

Summary. The in vitro susceptibility to amphotericin B, fluconazole, itraconazole and ketoconazole of 545 Candida strains from patients treated at the University Hospital of the Canaries was determined by means of a microdilution test. The distribution of the species was as follows: Candida albicans (342), Candida tropicalis (70), Candida glabrata (68), Candida parapsilosis (65). Of Candida albicans isolates, 8.5% and 7.6% showed resistance to itraconazole and fluconazole respectively. Of C. tropicalis isolates 34.3%, 27.1% and 2.9% were resistant to itraconazole, fluconazole and ketaconazole respectively. For C. glabrata , 10.3% and 4.4% of the isolates under study demonstrated resistance to fluconazole and itraconazole respectively. Only 4.6% and 1.5% of C. parapsilosis isolates demonstrated resistance to fluconazole and itraconazole respectively. C. tropicalis was the most resistant strain and C. parapsilosis the most sensitive. The greatest percentages of resistance in vitro were seen with the triazoles. Zusammenfassung. Es wurde die Empfindlichkeit von 545 Candida ‐Stämmen für Amphotericin B, Fluconazol, Itraconazol und Ketoconazol in vitro in einem Mikrodilutionstest bestimmt. Bei den Stämmen handelte es sich um Isolate von Patienten, die in der Universitäts‐Klinik der Kanarischen Inseln behandelt worden waren. Das Untersuchungsgut war wie folgt verteilt: 342 Candida albicans , 70 C. tropicalis , 68 C. glabrata , 65 C. parapsilosis. Bei C. albicans waren 8.5% gegen Itraconazol und 7.6% gegen Fluconazol resistent. Bei C. tropicalis wurden 34.3% resistent gegenüber Itraconazol befundet, 27.1% gegen Fluconazol und 2.9% gegen Ketoconazol. Bei C. glabrata waren 10.3% resistent gegen Fluconazol und 4.4% gegen Itraconazol. Candida parapsilosis wurde zu 4.6% gegen Fluconazol und zu 1.5% gegen Itraconazol als resistent befundet. Somit erwies sich C. tropicalis als die resistenteste und C. parapsilosis als die sensibelste Art.
