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...

Microbial fermentation for producing biodiesel from lignocellulosic hydrolysates is receiving increasing attention and attempts have been made to screen an oleaginous Trichosporon sp. with high lipid content and a strong tolerance to lignocellulose hydrolysates. In order to better understand mechanisms related to its lipid accumulation, metabolic flux analysis was performed under 5gL(-1) ammoni...

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 ...

Latex beads coated with anti-Cryptococcus neoformans antibody were agglutinated by serum from a bone marrow transplant recipient having a disseminated infection caused by Trichosporon beigelii. The cryptococcal latex agglutination titer in the serum of the patient rose to 1:2,560 by the time of his death. Necropsy confirmed the disseminated Trichosporon infection and absence of C. neoformans. C...

Trichosporon asahii is a basidiomycetous yeast which causes white piedra and onychomycosis in immunocompetent hosts as well as various localized and disseminated invasive infections in immunodeficient hosts. Urinary tract infection caused by Trichosporon asahii is rare. One month after posterior urethral valve surgery a seven-month-old male child presented with fever, severe vomiting and crying...

Ragi Tapai is a starter used for the fermentation of cassava and glutinous rice to produce conventional fermented products, such as in Indonesia. contains several enzymes microbes that help process. The purpose this study was identify most potential amylolytic yeast in-vitro (amylolytic, cellulolytic, fermentative). GPA, YEA, APB, CMCA, GPACaCO3 were medium selection characterization. result sh...
