Ring Worm


By DVM 360

Fungal skin infections occur commonly in show lambs during the late spring and summer months due to frequent short clipping and repeated bathing prior to shows. Ringworm is less common in goats unless they are exposed to sheep or their hair is clipped very short and they are bathed frequently. Classically, ringworm presents as round lesions with alopecia, scaling, erythema, and crusts, but a form in lambs known as club lamb fungus may exhibit raised thick plaques often about the ears, head and neck. Ringworm is readily transmitted to man, so producers treating affected animals should wear plastic gloves and wash their hands thoroughly afterwards. Veterinarians working at shows should not allow animals with ringworm to be exhibited. A variety of disinfectants including chlorhexidine, sodium hypochlorite, iodophors and benzalkonium chloride and garden fungicides such as captan have been used with varying degrees of success in treating livestock cases of ringworm.
