White piedra: molecular identification of Trichosporon inkin in members of the same family

Abstract

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 the agent as Trichosporon inkin.

Conclusions: White piedra and infection caused by T. inkin are rarely reported in Southern Brazil. The molecular tools are essentials on identifying the Trichosporon species.
