Cases of Libyostrongylus douglassii-associated proventriculitis in an adult female ostrich and two ostrich chicks occurring on two farms in different federal states of Germany are described. The adult bird was recently bought and kept under quarantaine conditions without contact to other animals of the herd. Without developing clinical signs of illness, the animal died. At necropsy, typical lesions of wireworm infection were found. The lining of the stomach had a moth-eaten appearance. Massive amounts of adult stages of trichostrongyloid nematodes were diagnosed in histological specimens of the proventricular mucosa and under the koilin layer of the ventriculus. The worms were isolated from the proventriculus and identified as L. douglassii. The feces of the bird contained high amounts of typical eggs of the worms with a medium size of approximately 70 x 40 microm. A polyphasic degeneration of heart and skeletal muscle was diagnosed in addition to the wireworm infection and interpreted to be a result of a malnutrition (Vit. E-/selenium deficiency). The ostrich chicks were reared on another farm and submitted for necropsy because of high mortality (8 out of 12 chicks died). A massive invasion of the proventricular mucosa with L. douglassi was macroscopically and histologically detected at necropsy of the anemic birds.
描述了在德国不同联邦州的两个农场中，一只成年雌性鸵鸟和两只鸵鸟雏鸟发生的与道氏利比亚圆线虫相关的前胃炎症病例。这只成年鸟是最近购买的，在隔离条件下饲养，未与畜群中的其他动物接触。该动物未出现疾病临床症状就死亡了。尸检时，发现了典型的铁线虫感染病变。胃黏膜呈虫蚀状外观。在前胃黏膜的组织学标本和砂囊角质膜层下诊断出大量毛圆科线虫成虫阶段。从腺胃中分离出这些蠕虫，并鉴定为道氏利比亚圆线虫。这只鸟的粪便中含有大量典型的虫卵，虫卵中等大小，约为70×40微米。除了铁线虫感染外，还诊断出心脏和骨骼肌的多相变性，并解释为营养不良（维生素E/硒缺乏）的结果。这些鸵鸟雏鸟在另一个农场饲养，因高死亡率（12只雏鸟中有8只死亡）而进行尸检。在对贫血雏鸟进行尸检时，肉眼和组织学检查均发现前胃黏膜被道氏利比亚圆线虫大量侵袭。
