Description    Ruminants in Brazil grazing the perennial shrub SIDA CARPINIFOLIA developed neurologic disease which was reproduced by experimental feedings. At necropsy there was vacuolation in several tissues and a pattern of staining consistent with alpha-mannosidosis; swainsonine was the toxic constituent of the plant.
