The "in vitro" antifungal activity of ozonized sunflower oil (Bioperoxoil®) was tested on 101 samples of yeasts originating from onychomycosis using the disk diffusion method. The oil was efficacious against several clinical fungal strains: Candida parapsilosis, Candida albicans, Trichosporon asahii, Candida tropicalis and Candida guilliermondii.

Fifty yeasts belonging to the genera Candida, Pichia, Saccharomyces, Cryptococcus, Rhodotorula and Trichosporon were identified by classical methods and by the API 20C AUX system. The commercial system correctly identified 92% of the species, with the need for additional tests in 16% of cases. The results were interpreted with good, very good and excellent identification.

We encountered a case of a 73-year-old man with acute myeloid leukemia who developed Trichosporon asahii systemic infection while on itraconazole prophylaxis during severe neutropenia. Cryptococcal antigen was useful for diagnosis. Although itraconazole was ineffective in protecting against trichosporonosis, treatment was successful with voriconazole following liposomal amphotericin B.

We describe an outbreak of Trichosporon asahii in 8 newborn infants with sepsis. Six out of these 8 infants died. The organism was identified on specific culture and morphologic characteristics. The organism was sensitive to amphotericin-B but resistant to fluconazole. Laminar flow unit was suspected to be the source of the outbreak.
