Plain-English summary
Researchers found a tiny worm called Ollulanus tricuspis in the stomachs of domestic cats. Out of 131 cats that had stomach biopsies taken during a procedure called endoscopy, four had this parasite. Three of these cats were mainly vomiting, while the fourth one was losing weight. Although the stomachs looked normal during the examination, two of the cats showed signs of chronic gastritis (long-term stomach inflammation) when looked at under a microscope, while the other two appeared normal. The exact impact of this parasite on the cats' health is still unclear, but this study is the first to identify it using routine biopsy samples.
Abstract
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.
