Elk as a Potential Host for Meningeal Worm: Implications for Translocation

Translocation of wild ungulates is a common wildlife management tool and an integral component of game farming activities throughout the world. Elk (Cervus elaphus) are a primary species being moved, and the possibility of translocating a hazardous parasite led us to examine the potential for elk to survive infections of meningeal worm (Parelaphostrongylus tenuis), to shed larvae in feces, and thus, to translocate the parasite. Twenty-six elk calves were exposed to 15-300 infective larvae of meningeal worm. All 13 elk exposed to >125 larvae developed neurologic disease and died; 2 shed larvae in feces prior to death
