| Popis: | Coyotes (Canis latrans) are resilient, adaptable, cosmopolitan omnivores that are increasingly prevalent in urban environments, where they interact with both humans and domestic dogs. Coyotes potentially transmit zoonotic parasites, including the tapeworm Echinococcus multilocularis, which appears to be increasing in prevalence in western North America. In this study, we analysed the carcasses of 23 urban coyotes in Edmonton, Alberta, Canada. Focusing primarily on the helminth community, we recovered three tapeworm species (E. multilocularis, Taenia pisiformis, T. serialis), four nematodes (Toxascaris leonina, Uncinaria stenocephala, Capillaria sp., Physaloptera sp.), and two trematodes (Alaria arisaemoides and A. americana). Compared to previous studies of urban coyotes conducted in North America, we report one of the highest levels of E. multilocularis infection in North America: 65.2% infection prevalence. These results amplify concerns expressed by others about the increasing prevalence of this zoonotic parasite and the role coyotes may play in parasite transmission. More research is needed to better understand how various ecological factors, urbanization and wildlife management practices influence the transmission of potentially zoonotic parasites such as E. multilocularis. |
