Abstract
|
|
|
|
Onychomycosis has been reported to be caused mainly by dermatophytes, yeast, and non-dermatophyte molds. Here, we report the first case of onychomycosis caused by Elsinoe species, which has been known as a phytopathogen that causes diseases in many plant hosts. The mold was isolated from the right great toenail of a 63-year-old woman with no history of underlying diseases. Cultured colony morphology showed slow-growing, erumpent, cerebriform, brownish to black-colored colonies, characteristic of Elsinoe species. Internal transcribed spacer (ITS) and large subunit (LSU) region sequence analyses were used for identification, and the results showed consistently high identity scores (>90%) for Elsinoe species. This is the first clinical case of Elsinoe species infecting a non-plant organism, particularly a human, as a host.
