A myodegeneration most frequent in calves and lambs whose dams have been fed during gestation or longer on feeds, especially legumes (Fabaceae), grown in certain areas where selenium is either deficient or unavailable in the soil. It has been recorded in many countries. It has been produced experimentally in several species of animals on low-selenium intake. A similar myopathy occurs naturally in goats, deer, foals, and dogs but proof of the etiology is lacking.

A disease affecting susceptible plants such as apples, pears, plums, cherries and roses when they are placed into soil previously occupied by a related species. The exact causes are not known, but in the first year the new plants will grow poorly. One theory is that replant disease is due to a whole menagerie of tree pathogens - fungi, bacteria, nematodes, viruses and other organisms.
