INTERNAL GROSS PATHOLOGY OF MOOSE EXPERIMENTALLY INFESTED WITH WINTER TICKS
Captive moose (Alces alces) infested with 21,000 and 42,000 larval winter ticks (Dermacentor albipictus) in September-October, and unifested moose were studied to assess impact of winter ticks on moose. Study animals were euthanized the following April near the end of the parasitic phase of winter t...
