ID#:15434
Description:This image depicts a right lateral view of a cow revealing a large, irregularly-shaped area about its head and neck, where the animal’s hair had fallen out, and where the skin had been replaced by a roughened, chronically-inflamed surface. The infection was due to a dermatophytic fungal infestation by Trichophyton verrucorum. See 15422, for a closer view of this cow’s head, and the extensive fungal infection involving that region.
T. verrucosum presents itself as a zoophilic, i.e., an affinity for animals, infection affecting horses and cattle, though can infect humans through by way of direct contact with an infected equine or bovine animal. When the organism affects the hair shaft, the infection presents itself as ectothrix invasion of the shaft.
