Fungal infections cause little, if any, permanent damage or economic loss.
However, because ringworm is a transmissable infectious disease, animals with lesions are barred from exhibitions or shows by regulations of the State Board of Animal Health. Infection of the skin and hair of cattle is most frequently due to Trichophyton verrucosum, a spore forming fungi. Spores are shed from the lesion by broken hairs or scabs from the lesion.

Show calves are frequently infected from spore contaminated equipment that has not been properly cleaned.
