Outbreaks of Wimmera rye grass toxicity in the south-west of Western Australia, and the associated distribution of Wimmera rye grass parasitised by Anguina sp and Corynebacterium sp were investigated. Between 1970 and 1974, 58 outbreaks occurred on 26 farms in sheep and cattle grazing pasture, cereal crop, stubble, screenings, or hay containing parasitised Wimmera rye grass. Morbidity rates up to 77% were observed. Clinical signs were characterised by staggering, collapse, periods of convulsions and other nervous signs, often followed by death. A pale, friable liver and haemorrhages in different organs were the most constant gross autopsy findings, but no specific histopathological changes were observed. Symptomatic treatment of affected animals and agronomic control measures attempted by farmers were unsuccessful in controlling the disease.
对西澳大利亚西南部维默拉黑麦草中毒的爆发情况，以及被鳗线虫属和棒状杆菌属寄生的维默拉黑麦草的相关分布进行了调查。1970年至1974年间，在26个农场发生了58起疫情，涉及放牧绵羊和牛的牧场、谷类作物、茬地、筛余物或含有被寄生维默拉黑麦草的干草。观察到发病率高达77%。临床症状表现为蹒跚、倒地、惊厥期和其他神经症状，常随后死亡。肝脏苍白、易碎以及不同器官出血是最常见的大体尸检发现，但未观察到特定的组织病理学变化。对患病动物进行的对症治疗以及农民尝试的农艺控制措施均未能成功控制该病。
