Captive moose calves (Alces alces) were used to study symptoms of Elaphostrongylus infections that affect moose and reindeer (Rangifer tarandus) in Scandinavia. Seven calves were infected experimentally with Elaphostrongylus alces larvae and three with E. rangiferi larvae. Both parasites produced ne...
