Abstract：
Nematode, cestode, protozoan, microsporidian, and pentastomid parasites affect domesticated and wild rabbits, hares, and jackrabbits of the genera Brachylagus, Lepus, Oryctolagus, Pentalagus, and Sylvilagus. Some endoparasite infections are of limited or no significance, whereas others have potentially profound consequences. Accurate identification of endoparasites of rabbits, hares, and jackrabbits is an important facet of the work of veterinary pathologists engaged in lagomorph pathology. Here I review endoparasites from the pathologist\'s perspective, focusing on pathogenesis, lesions, and implications of infection. Stomach nematodes Graphidium strigosum and Obeliscoides cuniculi are infrequently pathogenic but may cause gastritis and gastric mucosal thickening. Nematodes Passalurus ambiguus, Protostrongylus spp., Trichostrongylus spp., and Trichuris spp. are rarely associated with disease. Adult Capillaria hepatica (syn. Calodium hepaticum) nematodes and non-embryonated eggs cause granulomatous hepatitis in wild Oryctolagus cuniculus and Lepus europaeus, resulting in multifocal, off-white, hepatic lesions, which may be misdiagnosed as hepatic eimeriosis. When the rabbit is an intermediate host for carnivore cestodes, the space-occupying effects of Cysticercus pisiformis and Coenurus serialis may have pathologic consequences. Eimeria stiedai is a major cause of white-spotted liver in O. cuniculus, particularly in juveniles. Enteric coccidiosis is a noteworthy cause of unthriftiness in young animals, and frequently manifests as diarrhea with grossly appreciable multifocal off-white intestinal lesions. O. cuniculus is the natural host for the zoonotic microsporidian Encephalitozoon cuniculi. Infection may be acute and focused mainly on the kidneys, or it may follow a chronic disease course, frequently with neurologic lesions. A latent carrier status may also develop.
摘要：
线虫,食宿,原生动物,微孢子虫,五虫寄生虫会影响家兔和野兔，野兔,和Brachylagus属的野兔，Lepus,Oryctolagus,Pentalagus,还有Sylvilagus.一些体内寄生虫感染有限或没有意义，而其他人可能会产生深远的后果。准确识别兔子体内寄生虫，野兔,和jackrabins是兽医病理学家从事lagomorph病理学工作的一个重要方面。在这里，我从病理学家的角度回顾体内寄生虫，专注于发病机理，病变,以及感染的影响。胃线虫茎形藻和尖锐湿疣不常见，但可能引起胃炎和胃粘膜增厚。线虫Passalurusambiguus，原根菌属。,毛线菌属。,和Trichurisspp.很少与疾病相关。成年肝毛细血管（syn。肝叶线虫）线虫和非胚胎卵在野生小脑和欧洲小脑中引起肉芽肿性肝炎，导致多焦点，灰白色,肝脏病变,这可能会被误诊为肝eimeriosis。当兔子是食肉动物的中间宿主时，皮囊尾蚴和尾草的占据空间效应可能具有病理后果。Eimeriastiedai是O.cuniculus白色斑点肝脏的主要原因，尤其是青少年。肠球虫病是幼小动物营养不良的值得注意的原因，并经常表现为腹泻，伴有明显的多灶性灰白色肠道病变。O.cuniculus是人畜共患小孢子虫的自然宿主。感染可能是急性的，主要集中在肾脏，或者它可能遵循慢性疾病进程，经常有神经系统病变。潜在的载体状态也可能发展。
