Abstract

On 6 properties in south-western Queensland an outbreak of nervous disease occurred horses due to ingestion of Swainsonia (Darling pea). Loss of condition, depression, hyperaesthesia and hyperexcitability were seen in affected horses. At autopsy of 2 horses generalised c ytoplasmic vacuolation was seen in the neurones of the central nervous system and in the liver, adrenal and thyroid. The clinical and pathological features were similar to those described in horses suffering from Swainsona poisoning in Australia and Astragalus and Oxytropis in North America.

摘要

在昆士兰西南部的6处农场，马匹因摄入斯氏豆（达令豌豆）而爆发了神经系统疾病。患病马匹出现体重减轻、精神沉郁、感觉过敏和过度兴奋的症状。对2匹马进行尸检时，发现中枢神经系统、肝脏、肾上腺和甲状腺的神经元出现广泛性细胞质空泡化。这些临床和病理特征与澳大利亚患斯氏豆中毒的马匹以及北美患黄芪属和棘豆属中毒的马匹所描述的特征相似。
