Yeasts are a polyphyletic group of ascomycete and basidiomycete fungi characterized by having a unicellular growth phase and sexual stages that are not enclosed in fruiting bodies. An attempt was made to identify yeast species in uncultivated soils collected from different areas of Kermanshah province, Iran, by analyzing hypervariable D1/D2 domain of the large subunit (LSU) rDNA gene sequencean...

In this study the molecular identification and susceptibility profile of 21 clinical isolates, from a Brazilian hospital, belongs to six different species of Trichosporon were described. Trichosporon asahii was the predominant species and corresponded to 43% of isolates. Eighty three percent of the strains isolated from deep sites were identified as T. asahii, while only 17% belong to a non-T. ...

Trichosporon inkin is one of six pathogenic species of the genus Trichosporon and the etiologic agent of pubic white piedra. Trichosporon species have been reported as a cause of disseminated infections, particularly among immunosuppressed patients. We describe the third reported case of T. inkin peritonitis associated with peritoneal dialysis and the first to be treated with caspofungin.

INTRODUCTION White piedra is a superficial mycosis caused by the genus Trichosporon and characterized by nodules on hair shaft. METHODS The authors report a family referred to as pediculosis. Mycological culture on Mycosel® plus molecular identification was performed to precisely identify the etiology. RESULTS A Trichosporon spp. infection was revealed. The molecular procedure identified th...

Trichosporon species are opportunistic pathogens, associated with a high mortality rate in immunocompromised patients. Oligonucleotide primers were used to amplify a 170-bp fragment of small-subunit ribosomal DNA of all species in the genus Trichosporon by PCR. The primers amplify DNAs of all species in the genus Trichosporon, including six causative agents of trichosporonosis. DNAs of other me...

Accurate species identification of Candida, Cryptococcus, Trichosporon and other yeast pathogens is important for clinical management. In the present study, we developed and evaluated a yeast species identification scheme by determining the rDNA internal transcribed spacer (ITS) region length types (LTs) using a sequencer-based capillary gel electrophoresis (SCGE) approach. A total of 156 yeast...

Trichosporonosis is an uncommon but frequently fatal mycosis in immunocompromised patients. A multicenter retrospective study was conducted to characterize cases of proven or probable invasive trichosporonosis diagnosed over the past 20 years in Italian patients with hematological diseases. Of the 52 cases identified, 17 were classified as Trichosporon sp. infections and 35 were attributed to G...

Yeasts cause only 5-10% of onychomycosis; the most common yeast is Candida albicans, and rarely Trichosporon spp. is found. Recently, it has become an important cause of fungemia with a high mortality rate in immunocompromised patients. Superficial infections caused by Trichosporon spp., including piedra and onychomycosis, occur in immunocompetent patients. Herein, we report a case of a fungal ...
