Ollulanus tricuspis is a small nematode parasite of the stomach, and its infection has been reported worldwide in cats but only one report in dogs as post-mortem diagnosis. Two dogs, kept in the Tokyo area, were presented for chronic vomiting. Chronic gastritis was diagnosed histologically, and many nematodes were detected in endoscopically-biopsied gastric samples and in the mucus of vomitus in both dogs. The parasites were small (<1 mm), and their morphological characteristics were consistent with those previously reported for O. tricuspis. The symptoms in one dog completely disappeared after anthelmintic therapy. To our knowledge, this is the first report describing ante-mortem diagnosis of spontaneous gastric O. tricuspis infection in dogs in which infectivity and pathogenicity of the nematode are suggested.
三尖瓣奥氏线虫是一种寄生于胃内的小型线虫寄生虫，其感染在全球范围内的猫中均有报道，但在犬中仅有一例死后诊断的报告。两只饲养在东京地区的犬只因慢性呕吐前来就诊。经组织学诊断为慢性胃炎，在内镜活检的胃样本以及两只犬呕吐物的黏液中均检测到许多线虫。这些寄生虫很小（<1毫米），其形态特征与先前报道的三尖瓣奥氏线虫一致。其中一只犬在驱虫治疗后症状完全消失。据我们所知，这是第一份描述犬自发性胃三尖瓣奥氏线虫感染生前诊断的报告，该报告提示了该线虫的感染性和致病性。
