Abstract
Contracaecum spp. (Nematode: Ascaroidea) caused gastric ulcers in a Steller sea lion from the California coast and a white pelican from Tule Lake, California. The parasite penetrated deeply into the gastric wall, causing extensive inflammtory reaction. A hyaline material formed a mold surrounding the head of the nematode in the granulation tissue.
