Experimental Elaphostrongylus Cervi Infection in Moose (Alces Alces)
An 8-week-old male moose calf was inoculated with 360 infective third-stage larvae (L3) of E. cervi. The calf started to expel first-stage larvae (L1) of E. cervi in faeces 63 days after inoculation. The highest faecal larval count of 1,920 L1 per gram faeces was recorded 133 days post inoculation....

An 8-week-old male moose calf was inoculated with 360 infective third-stage larvae (L3) of E. cervi. The calf started to expel first-stage larvae (L1) of E. cervi in faeces 63 days after inoculation. The highest faecal larval count of 1,920 L1 per gram faeces was recorded 133 days post inoculation. Clinically, intermittent lameness, mild ataxia and general stiffness were observed over a 3 months’ period from day 75 after inoculation.
