On thirty one examined ringed seals from Arviat, thirteen were infected by 1 to 24 anisakids. Identification of nematodes from their stomachs showed two species; Contracaecum osculatum (sensu lato) (79 specimens) and Pseudoterranova decipiens (sensu lato) (11 specimens). In the gastric sections with parasites, larvae and adults of nematodes were present mainly in the fundic portion of the stomach. The anterior parts of the nematodes were embedded in mucosa and submucosa. Anisakids were associated with ulcerous gastric lesions and raised inflammatory areas in the stomachs. The histological examination of a sample taken from the tissue surrounding anisakids revealed the presence of more or less confluent focal necrotic areas. Most small petechial hemorrhages were located in the mucosal layer of the gastric wall and were surrounded by inflammatory mononuclear cells such as lymphocytes, histiocytes, eosinophils and fibroblasts. The Anisakidae larvae in the stomach caused atrophy of glands, hemorrhaging and eosinophilic infiltrations that consequently healed, creating fibrotic scars.<\/jats:p>","DOI":"10.2478\/pjvs-2013-0009","type":"journal-article","created":{"date-parts":[[2013,5,30]],"date-time":"2013-05-30T20:41:06Z","timestamp":1369946466000},"page":"63-67","source":"Crossref","is-referenced-by-count":1,"title":["Pathological
