a chronic, infectious disease of animals, accompanied by inflammatory thickening of dense connective tissue, sometimes resembling tumors. The disease is caused by the fungus Botryomyces ascoformans and is localized mainly in places where a harness touches the skin, on the stump of the spermatic cord, and in the muscles, lymph nodes, and udder. The disease affects horses and, less frequently, cattle, sheep, and pigs. The economic loss is insignificant. The treatment is surgical.
