title: A gastric nematode (Ollulanus tricuspis) in cats in the Pacific Northwest.
abstract: Ollulanus tricuspis, a minute gastric nematode not previously documented in the United States, was identified by histologic examination and by dissecting microscopic examination of stomach contents of 7 cats from 3 breeding colonies in the Pacific Northwest. The nematode may have contributed to chronic weight loss and undernutrition in part by causing gastric irritation, with resultant vomiting. The findings suggest that infection with Ollulanus parasites may be more widespread in the United States than realized.
