title: Intraspecies diversity of Cryptococcus albidus isolated from humans as revealed by sequences of the internal transcribed spacer regions.
abstract: The basidiomycetous yeast, Cryptococcus albidus, shows intraspecies diversity, but it is rarely isolated from immunocompromised patients. Nineteen strains of C. albidus, including nine clinical isolates, were re-classified by sequences of their rRNA internal transcribed spacer (ITS) regions. The nine clinical isolates were genetically diverse and included both C. albidus and C. diffluens. One clinical isolate, recovered from the blood of an AIDS patient, represented a new species. Only small differences were found in the biochemical and serological characteristics of C. albidus and C. diffluens. All isolates were sensitive to amphotericin B, but several isolates were resistant to fluconazole and itraconazole. C. albidus heterogeneity should be taken into consideration when identifying clinical isolates.
