Trichosporon asahii is a major causative agent of
deep-seated trichosporonosis, which has a high mortality rate. To
detect T. asahii, we have developed specific
oligonucleotide primers based on the internal transcribed spacer
regions of this organism's genome. Amplification products were
selectively obtained from only T. asahii DNA; the DNAs
of other Trichosporon species, as well as those of
medically relevant yeasts such as Candida albicans, Cryptococcus neoformans, and Malassezia furfur,
were not amplified. This detection system will be useful as a
microbiological tool for the diagnosis of trichosporonosis.
