Elaphostrongylus Cervi Infection in Moose (Alces Alces). Prevalence and Pathological Changes in Relation to Age and Season
The prevalence of Elaphostrongylus cervi infection in 8–10-month-old moose calves shot in March/April in Southeastern Norway was studied. The prevalence was compared with the prevalence of infection in 4–6- and 16–18-month-old animals shot in September/October. The location of adult worms, the patho...

The prevalence of Elaphostrongylus cervi infection in 8–10-month-old moose calves shot in March/April in Southeastern Norway was studied.
