Outbreak of parasitic peritonitis in reindeer in Finland
In 2003, there was an outbreak of peritonitis in reindeer in the southern and middle part of the Finnish reindeer herding area caused by the filarioid nematode Setaria species. In the province of Oulu, the proportion of reindeer viscera condemned owing to parasitic lesions increased from 4·9 per cen...
