Grazing sheep and goats are constantly exposed to helminth infections in many parts of the world, including several trematode species that causes a range of clinical diseases. The clinical picture of flukes is dependent upon the organs in which they develop and the tissues they damage within the respective organs. Accordingly, infections with the common liver fluke , which, as juvenile worm migrates through the liver parenchyma for several weeks, may be associated with hepatic disorders such as impairment of carbohydrate, protein and fat metabolism, followed by chronic wasting. In contrast, the lancet fluke , which does not exhibit tissue migration and thus does not lead to major tissue damage and bleeding, also does not lead to significant clinical symptoms. Rumen flukes such as cause catarrhal inflammation during their migration through the intestinal and abomasal epithelium during its juvenile stages. Depending on the infection intensity this may result in a range of clinical symptoms including diarrhoea, inappetence or emaciation. In this review, we aim to provide an update on the current knowledge on flukes particularly concerning the clinical relevance of the most important fluke species in sheep.
在世界许多地区，放牧的绵羊和山羊经常受到蠕虫感染，包括几种可引发一系列临床疾病的吸虫。吸虫的临床表现取决于它们发育的器官以及它们在各个器官内所损害的组织。因此，感染常见的肝吸虫时，幼虫在肝实质中迁移数周，可能会引发肝脏疾病，如碳水化合物、蛋白质和脂肪代谢受损，继而出现慢性消瘦。相比之下，矛形双腔吸虫不会出现组织迁移，因此不会导致严重的组织损伤和出血，也不会引发明显的临床症状。瘤胃吸虫，如 ，在幼虫阶段穿过肠道和皱胃上皮迁移时会引起卡他性炎症。根据感染强度的不同，这可能导致一系列临床症状，包括腹泻、食欲不振或消瘦。在本综述中，我们旨在提供有关吸虫的最新知识，特别是关于绵羊中最重要的吸虫种类的临床相关性。
