This study describes an occurrence of pink morning glory (Ipomoea carnea) intoxication in goats in northern Argentina. The clinical signs displayed by the affected animals were ataxia, lethargy, emaciation, hypertonia of the neck muscles, spastic paresis in the hind legs, abnormal postural reactions and death. The clinico-pathologic examination revealed that the affected animals were anemic and their serum level of aspartate aminotransferase was significantly increased. Cytoplasmic vacuolation in the Purkinje cells and pancreatic acinar cells was observed by histological examination. The neuronal lectin binding pattern showed a strong positive reaction to WGA (Triticum vulgaris), sWGA (succinylated T. vulgaris) and LCA (Lens culinaris). Although I. carnea is common in tropical regions, this is the first report of spontaneous poisoning in goats in Argentina.
本研究描述了阿根廷北部山羊发生的粉红牵牛（Ipomoea carnea）中毒事件。患病动物表现出的临床症状有共济失调、嗜睡、消瘦、颈部肌肉张力亢进、后腿痉挛性轻瘫、异常姿势反应以及死亡。临床病理检查显示，患病动物贫血，其血清天冬氨酸转氨酶水平显著升高。组织学检查观察到浦肯野细胞和胰腺腺泡细胞出现细胞质空泡化。神经元凝集素结合模式显示对小麦胚芽凝集素（WGA）、琥珀酰化小麦胚芽凝集素（sWGA）和菜豆凝集素（LCA）有强烈阳性反应。尽管粉红牵牛在热带地区很常见，但这是阿根廷山羊自发性中毒的首例报告。
