Gastritis, vomition and weight loss are common in captive cheetahs (Acinonyx jubatus). Gastric spiral bacteria (Helicobacter spp.) and the very small, viviparous nematode Ollulanus tricuspis, a stomach worm of cats, are believed to be important causes. Three sibling cheetahs at Wellington Zoo, New Zealand, developed chronic vomiting, diarrhoea and debility. Their parents were both South African-born. Response to antibacterial treatment was poor. Endoscopic examinations revealed chronic lymphoplasmacytic gastritis and Ollulanus infection. Treatment with oxfendazole and pyrantel embonate resulted in clinical improvement; however, 1 cheetah, which died 7 months later as a result of a ruptured liver due to hepatic amyloidosis, still had Ollulanus worms present in her stomach. Ollulanus tricuspis is a significant cause of gastritis and vomiting in captive cheetahs, lions and tigers, as well as wild cougars and tigers. The parasite has not yet been found in sub-Saharan Africa. Because of the unusual characteristics of this parasite, the literature on its life history and techniques for diagnosis is reviewed.
胃炎、呕吐和体重减轻在圈养猎豹（猎豹属）中很常见。胃螺旋菌（幽门螺杆菌属）和非常小的胎生线虫三毛奥鲁线虫（猫的一种胃蠕虫）被认为是重要病因。新西兰惠灵顿动物园的三只同胞猎豹出现了慢性呕吐、腹泻和身体虚弱。它们的父母均出生于南非。对抗菌治疗的反应不佳。内镜检查显示为慢性淋巴细胞性胃炎和奥鲁线虫感染。用奥芬达唑和双羟萘酸噻嘧啶治疗后临床症状有所改善；然而，1只猎豹7个月后因肝淀粉样变性导致肝脏破裂死亡，其胃中仍有奥鲁线虫。三毛奥鲁线虫是圈养猎豹、狮子和老虎以及野生美洲狮和老虎中胃炎和呕吐的重要病因。在撒哈拉以南非洲尚未发现这种寄生虫。由于这种寄生虫的特殊特性，本文对其生活史和诊断技术的文献进行了综述。
