Abstract
We used standardized flotation
techniques to survey 56 grizzly bear (Ursus arctos) fecal samples for
parasites. The samples were collected during the spring and autumn of 1995
and 1996 in the central Arctic of the Northwest Territories, Canada.
Parasites of the genera Nematodirus, gastrointestinal coccidia, and
an unidentified first stage protostrongylid larva are reported for the first
time from grizzly bear feces in North America. Parasites of the genera
Diphyllobothrium and Baylisascaris were also recovered.
Prevalence of gastrointestinal parasites was significantly different between
the spring and autumn seasons (31% and 58% respectively). Thus, we provide
evidence supporting the theory that bears void gastrointestinal parasites
before hibernation. |
