EPIZOOTIOLOGY OF ELAPHOSTRONGYLUS ALCES IN SWEDISH MOOSE
A total of 961 harvested and 241 unharvested moose (Alces alces) carcasses and parts from throughout Sweden were examined for Elaphostrongylus alces from 1985 to 1989. When available, the central nervous system and skeletal muscles were searched for adult nematodes, and lungs and feces were examined...

The parasite was distributed throughout Sweden with highest prevalence (56%) in the central region and lowest in the south (13%).
