Taxonomic position of deep-seated, mucosa-associated, and superficial isolates of Trichosporon cutaneum from trichosporonosis patients

Trichosporon and trichosporonosis

Trichosporon is a genus of anamorphic fungi in the family Trichosporonaceae. All species of Trichosporon are yeasts with no known teleomorphs. Most are typically isolated from soil, but several species occur as a natural part of the skin microbiota of humans and other animals. Proliferation of Trichosporon yeasts in the hair can lead to an unpleasant but non-serious condition known as white pie...

cis,cis-Muconate cyclase from Trichosporon cutaneum.

The inducible enzyme catalysing the conversion of cis,cis-muconate to (+)-muconolactone was purified 300-fold from the yeast Trichosporon cutaneum, grown on phenol. The enzyme has a sharp pH optimum at pH 6.6. It reacts also with several monohalogen derivatives and with one monomethyl derivative of cis,cis-muconate, but not with cis,trans- or trans,trans-muconate or 3-carboxy-cis,cis-muconate. ...

Current knowledge of Trichosporon spp. and Trichosporonosis.

Trichosporon spp. are basidiomycetous yeast-like fungi found widely in nature. Clinical isolates are generally related to superficial infections. However, this fungus has been recognized as an opportunistic agent of invasive infections, mostly in cancer patients and those exposed to invasive medical procedures. It is possible that the ability of Trichosporon strains to form biofilms on implante...

Trichosporon cutaneum C.A.P.D. peritonitis.

Uptake of phenol by Trichosporon cutaneum.

The soil yeast Trichosporon cutaneum, which is distinguished by having a strictly oxidative metabolism, can be induced to utilize phenol as a sole carbon source. The present paper shows that such phenol-induced cells contain a specific, energy-dependent uptake system for phenol. Phenol uptake is not directly linked to its o-hydroxylation inside the cell, the first step of phenol metabolism. The...
