The stomach worm of the cat with an unusual cycle has a special place among the nematodes. O. tricuspis can develop and breed endogen as well as exogen, the infection of other hosts with freedom of movement, takes place through the ingestion of vomitus material containing parasites. As the conventional coproscopic methods of routine diagnosis have failed, the examination of gastric mucus or gastric mucosal scrapings post mortem offers itself. Intra vitam a provocated vomitus or a gastric irrigation are the diagnostic methods of choice. Increased vomiting of unknown genesis should, however, evoke suspicion relating to an O. tricuspis-infection and suggest an examination of the material. Besides the cat, dog, pig, wild cat, fox, cheetah, lion and tiger act as natural or inadequate hosts. Pathological alterations or clinical symptoms are more obvious in unusual carriers of parasites. Therapeutically only Citarin 2,5% was convincing.
具有异常生命周期的猫胃线虫在线虫中占有特殊地位。三尖瓣奥斯特线虫可在体内和体外发育繁殖，通过摄入含有寄生虫的呕吐物感染其他可自由活动的宿主。由于常规的粪便镜检方法无法确诊，因此死后检查胃黏液或胃黏膜刮片是可行的方法。生前诱发呕吐或洗胃是首选的诊断方法。然而，不明原因的呕吐增加应引起对三尖瓣奥斯特线虫感染的怀疑，并建议对呕吐物进行检查。除猫外，狗、猪、野猫、狐狸、猎豹、狮子和老虎都是天然或非适宜宿主。在寄生虫的异常宿主中，病理改变或临床症状更为明显。在治疗方面，只有2.5%的西他林有效果。
