An acute afebrile paretic condition was diagnosed in 16 of 100 feeder pigs between eight to ten weeks of age. Nine pigs died acutely and seven pigs were euthanized. Macroscopic lesions in the ventral horns of the cervical, thoracic, lumbar and sacral segments of the spinal cord consisted of focal, bilateral, grey depressed areas. There was a bilateral symmetrical focal poliomyelomalacia histopathologically characterized by microcavitation, endothelial and glial cell proliferation and infiltration of eosinophils. Clinical and pathological findings resemble spontaneous and experimental lesions associated with acute nicotinamide deficiency and selenium toxicosis in swine.
在100头8至10周龄的育肥猪中，有16头被诊断出患有急性无热麻痹症。9头猪急性死亡，7头猪被实施安乐死。脊髓颈段、胸段、腰段和骶段腹角的宏观病变表现为双侧局灶性灰色凹陷区域。组织病理学检查发现双侧对称性局灶性脊髓软化，其特征为微腔形成、内皮细胞和神经胶质细胞增殖以及嗜酸性粒细胞浸润。临床和病理结果与猪急性烟酰胺缺乏和硒中毒相关的自发性及实验性病变相似。
