摘 要：
首次报道了国内圈养斑纹角马肝片吸虫病确诊病例。诊断依据:(1)提示性临床症状:贫、消瘦、营养不良;(2)尸体剖检特征性病理变化:胆管显著扩张和胆管内挤排出大量肝片吸虫成虫的虫体;(3)肝片吸虫感染强度测定:运用麦克马斯特法测定了病死角马肝片吸虫感染强度为1 600个/g;(4)中间宿主调查:角马的饲养区内发现大量椎实螺,椎实螺体内含有大量的肝片吸虫尾蚴;(5)组织病理学检查:细支气管和肺泡腔内见有童虫的虫体结构。首次证实了角马肝片吸虫感染时,童虫在移行过程中可误移至肺,导致肺的病理变化。该病的发生与环境潮湿多水、环境中存在大量椎实螺而未被重视有关。肝片吸虫宿主范围广,应重视易感动物的生活环境,定期粪检确定感染率和感染强度,以及选择有效的药物防治,这是科学预防该病的关键。

摘 要：
Infection of Fasciola hepatica in captive wildebeest(Connochaetes taurinus)was confirmed and is first reported here.The wildebeest died due to the infection.Severe anaemia,wasting disease and malnutrition were observed after postmortem examination;Necroscopy showed that bile ducts were expended and became thickened,and were filled with large numbers of Fasciola hepatica.The intensity of infection was determined by the McMaster method and 1 600 ova were obtained per gram of faeces.Many Lymnaeidae snails,the intermediate host of Fasciola hepatica.were found in the wildebeest feeding yard,and many miracidia were observed in the Lymnaeidae bodies.Pathological lesions in the lungs were examined and microstructures of immature flukes were found in bronchioles and alveolar cavities.This was the first confirmation of migration by immature flukes into the lungs in wildebeest.We concluded that occurrence of fascioliasis was closely related to a damp or wet environment where Lymnaeidae snails existed.The keys to prevent the disease are to pay attention to the environments of susceptible animals,reduce the intermediate host snail population,check the infection intensity,and choose effective drugs to remove flukes from affected animals.
