Abstract: Ipomoea carnea subsp. fistulosa is a swainsonine-containing plant causing a glycoprotein storage diseases in ruminants, mainly in goats in northeastern Brazil. Seven farms were visited on the Marajo Island, state of Pará, northern Brazil, six in the municipality of Cachoeira do Arari and one in the municipality of Soure. In all farms native pastures had shortage of forage and were largely invaded by I. carnea subsp. fistulosa. On the three farms goats presented difficulties in standing, ataxia, hypermetria, wide-based stance, lateral gait, intention tremors, spastic paresis or weakness, abnormal postural reactions, nystagmus, loss of equilibrium and falling to the side or backward. On two farms the prevalence was of 32% (23/71) and 100% (32/32). On another farm one goat out of 19 had severe clinical signs, but the others of the flock were not examined clinically. Cattle, sheep and buffaloes were not affected. Six goats were euthanized and necropsied. No gross lesions were observed. Upon histological examination the main lesion was the vacuolization of the perikaryon of neurons and cytoplasm of epithelial cells of thyroid, liver, kidney, pancreas and macrophages of different organs. In the central nervous system the vacuolization of the perikaria was more severe in Purkinje cells of the cerebellum and in nuclei of the brain stem, mainly the cerebellar nuclei. Wallerian degeneration of axons and gliosis was also observed. The high frequency of the disease on the three farms suggests that poisoning by I. carnea subsp. fistulosa is very important for goats on Marajó Island where there are large amounts of the plant in the pastures.
