Surrogate hosts: Hunting dogs and recolonizing grey wolves share their endoparasites
Understanding how closely related wildlife species and their domesticated counterparts exchange or share parasites, or replace each other in parasite life cycles, is of great interest to veterinary and human public health, and wildlife ecology. Grey wolves (Canis lupus) host and spread endoparasites...

Understanding how closely related wildlife species and their domesticated counterparts exchange or share parasites, or replace each other in parasite life cycles, is of great interest to veterinary and human public health, and wildlife ecology. Grey wolves (Canis lupus) host and spread endoparasites that can either directly infect canid conspecifics or their prey serving as intermediate hosts of indirectly transmitted species. The wolf recolonization of Central Europe represents an opportunity to study parasite transmission dynamics between wildlife and domestic species for cases when a definitive host returns after local extinction – a situation equivalent to a ‘removal experiment’. Here we investigate whether the re–appearance of wolves has increased parasite pressure on hunting dogs – a group of companion animals of particular interest as they have a similar diet to wolves and flush wolf habitats when hunting. We compared prevalence (P) and species richness (SR) of helminths and the protozoan Sarcocystis to determine whether they were higher in hunting dogs from wolf areas (ndogs = 49) than a control area (ndogs = 29) without wolves. Of particular interest were S. grueneri and S. taeniata, known as ‘wolf specialists’. Five helminth and 11 Sarcocystis species were identified, of which all helminths and eight Sarcocystis species were shared between dogs and wolves.
