title: Dermatophytosis in farmed mink (Mustela vison) caused by Trichophyton equinum.
abstract: This report details 2 outbreaks of dermatophytosis in 2 different mink ranches. On the first farm, only kits were affected, while on the second farm, small numbers of adults were infected. Affected mink were otherwise clinically healthy and in good body condition. Three animals were euthanized and submitted for autopsy. Grossly, mink exhibited locally extensive to coalescing areas of crusting alopecia but no other significant gross lesions in internal organs. Microscopically, skin lesions were characterized by chronic hyperplastic dermatitis with folliculitis, furunculosis, occasional intracorneal pustules, and large numbers of intrafollicular fungal arthrospores and hyphae. The dermatophyte was cultured and identified as Trichophyton equinum based on molecular barcoding of the internal transcribed spacer region of the ribosomal DNA gene.
