Abstract

A fungus was isolated from a nail of a 54-year-old female patient with onychomycosis in Taiwan. Based on ITS rDNA as well as beta tubulin gene sequences and microscopic analyses, this fungus was identified as Exophiala oligosperma. This is the first record of E. oligosperma in Taiwan. Negative keratin azure test indicates that keratin degradation is not involved in cases of E. oligosperma associated with skin and nail diseases.

Keywords: Black yeasts; Dermatophytes; Keratin degradation.
