Cestodes in Eurasian wolves () and domestic dogs () in Switzerland.

Int J Parasitol Parasites Wildl

April 2025

Institute of Parasitology, Vetsuisse Faculty, University of Bern, Länggassstrasse 122, 3012, Bern, Switzerland.

Eurasian wolves () and domestic dogs () are definitive hosts of numerous cestode species. While infections with adult stages in canids are usually subclinical, some species pose a zoonotic risk or cause infections in wildlife and livestock, resulting in disease and/or economic losses. This study aimed to determine the prevalence, species composition, and geographical distribution of cestode infections in dogs and free-ranging wolves in Switzerland.

Large-scale molecular survey for piroplasmids in Iberian wild carnivores.

Parasitol Res

December 2024

Animal Health Department, Faculty of Veterinary Medicine, Universidad Complutense of Madrid, Madrid, Spain.

Piroplasmids are vector-borne hemoprotozoan parasites belonging to the phylum Apicomplexa that are of veterinary and medical importance. Wild carnivores are hosts for diverse piroplasmids, some of which are highly pathogenic for domestic dogs and cats. A large-scale survey including samples from 244 individuals belonging to eleven different species that were opportunistically obtained between 1993 and 2015 in four Autonomous Regions in Spain were tested for piroplasmid DNA with two different nested-PCR assays targeting the 18S rRNA gene.

As predators of a wide variety of livestock and wildlife species, wolves (Canis lupus) could serve as definitive hosts for species of Sarcocystis parasites infecting many intermediate hosts. Sarcocystis sporocysts have been observed in the feces of wolves fed infected beef before, but genetic tools have not yet definitively identified which species of parasites they harbor, impairing understanding of their contribution to infections in wild and domesticated intermediate hosts. Therefore, we genetically characterized sporocysts derived from a small sample of naturally infected wolves in Minnesota.
