The first isolation of ustilaginomycetous anamorphic yeasts, Pseudozyma species, from patients' blood and a description of two new species: P. parantarctica and P. thailandica.
The genus Pseudozyma is ustilaginomycetous anamorphic yeasts, and are mainly isolated from plants. We isolated three Pseudozyma strains from the blood of patients in Thailand. While one isolate was identified as P. antarctica by rDNA sequence analysis, the other two were considered to be new species and were named P. parantarctica and P. thailandica. The three isolates proved to be resistant to 5-flucytosine, and P. thailandica was also resistant to fluconazole and itraconazole. As far as we know, this is the first isolation of Pseudozyma strains from humans. The two new species are described.
