title: Diseases and parasites in wolves of the Riding Mountain National Park region, Manitoba, Canada.
abstract: We examined wolf (Canis lupus) blood and fecal samples from the Riding Mountain National Park (RMNP) region of Manitoba, Canada. In 601 fecal samples collected during two study periods in RMNP and the Duck Mountain Provincial Park and Forest (DMPPF) we found gastrointestinal helminth eggs from Alaria sp. (15.5%), Capillaria sp. (1.0%), taeniid tapeworms (30.8%), Toxascaris sp. (1.7%), Toxocara sp. (0.2%), Trichuris sp. (2.2%), and Moniezia sp. (0.5%). In addition, we found Demodex sp. (0.2%) and the protozoal cysts/oocysts of Sarcocystis sp. (37.3%), Cryptosporidium sp. (1.2%), coccidia (Isospora sp. or Eimeria sp.) (1.7%), and Giardia sp. (29.5%). No fecal shedding of canine parvovirus (CPV, n=387) was detected. All 18 blood samples collected in RMNP showed CPV exposure and eight of 18 blood samples indicated canine distemper virus (CDV) exposure. One wolf died from CDV. Our results are consistent with previous findings on pathogens affecting wolves and with high Giardia sp. prevalence in wolves inhabiting agricultural regions.
