Development of a Peptide Nucleic Acid Probe to Trichosporon Species and Identification of Trichosporonosis by Use of In Situ Hybridization in Formalin-Fixed and Paraffin-Embedded (FFPE) Sections

In order to identify Trichosporon species in formalin-fixed and paraffin-embedded sections from which visual discrimination of non-glabrata Candida species is mostly ineffective but critical for the choice of antifungals, we tested the usefulness of a newly designed peptide nucleic acid probe (PNA) for in situ hybridization (ISH). Results confirmed the usefulness of ISH with our PNA probe in identifying Trichosporon species from Candida albicans.MicrobiologySCI(E)4ARTICLE1295-2985
