Ringworm in sheep, along with other animals, is caused by two genera of fungi. These two fungi are Trichophyton and Microsporum, which a lot of times obligate parasites of the wool, hair and skin.
Ringworm is very contagious from animal to animal, especially in dense population conditions.
Not only does ringworm spread from animal to animal, but to humans as well. It can cause very severe skin lesions to anyone who comes in contact with the infected animal. Usually the clinical severity on humans is worse than how bad the host is infected. If severe enough ringworm can cause scarring. Prepare for Fungus at Lamb Shows Sheep exhibitors should prepare for summer shows by examining your sheep for the show ring.
