Research output: Contribution to journalArticle (Academic Journal)peer-review


Ollulanus tricuspis is a small nematode of the family Ollulanidae, found in the stomach of domestic cats and other felids. Of 131 gastric biopsy samples collected at endoscopic examination, four were shown to contain the parasite. Vomiting was the main presenting sign in three cats and weight loss in the fourth. The stomachs were grossly normal on endoscopic examination. Chronic gastritis was observed histologically in two cases, while the remaining cases were microscopically normal. The significance of the parasite remained undetermined. To our knowledge, this is the first report of O. tricuspis infection in domestic cats in which the diagnosis was made by examining routine endoscopic biopsy samples.
