Sarcocystis arctica (Apicomplexa: Sarcocystidae): ultrastructural description and its new host record, the Alaskan wolf (Canis lupus)

Abstract Sarcocystis sarcocysts are common in muscles of herbivores but are rare in muscles of carnivores. Here, we report sarcocysts in the muscles of a gray wolf (Canis lupus) from Alaska, USA, for the first time. Sarcocysts extracted from the tongue of the wolf were up to 900 μm long and slender and appeared to have […]

Echinococcus multilocularis in North America: the great unknown

Over the last decade, studies have begun to shed light on the distribution and genetic characterization of Echinococcus multilocularis, the causative agent of alveolar echinococcosis (AE), in North America. Recent findings indicate that the parasite is likely expanding its range in the central region of the United States and Canada and that invasions of European strains […]

Coping with wolves in Wisconsin: Part 1

When I visited the 400-acre farm of Eric and Sue Koens last summer, Eric remarked that, had he known in 1978 what he knows now, he would have purchased farmland in Missouri. What he didn’t know in 1978 when he purchased a former dairy farm in Rusk County, Wisconsin, was that wolves would become a […]

Disease, wolves top list of Minnesota moose killers

Preliminary results from tracking 173 adult moose that were captured and fitted with GPS radio collars from 2013 to 2015 show that two-thirds of the 47 that later died succumbed to various health problems. Another third were killed by wolves, but 25 percent of those moose had illnesses that made them easy prey, and some […]

Neosporosis: Recognizing and Preventing Neospora caninum Infections

*Staff Note* – We know from several studies, that the gray wolf, and thus all wolves, as well as canines in general, are definitive hosts of Neospora Caninum. It has been noted by science members of Wolf Education International, that this particular report does not do a good enough job in pointing out that wolves, […]

Canines Host to Abortion-Causing Parasite

Eventually, after submitting fetuses to the Wisconsin Veterinary Diagnostic Laboratory for testing, the Koenses found the cause of their herd abortion problem to be Neospora caninum, a protozoan parasite that can affect a variety of large and small animal species, including cows, sheep, deer, goats and horses. The parasite causes a disease called neosporosis, which […]

Effects of Wolves and Other Predators on Farms in Wisconsin: Beyond Verified Losses

With the recolonization of gray wolves (Canis lupus) across the Western Great Lake States (Minnesota, Michigan, and Wisconsin) there has been a concomitant increase in livestock depredations caused by wolves (Mech 1998, Ruid et al. 2005, Treves et al. 2002, USDA 2006, Wydeven et al. 2006). Wolf populations in Wisconsin have grown from 25 in […]

The occurrence of taeniids of wolves in Liguria (northern Italy)

Abstract Canids are definitive hosts of Taenia and Echinococcus species, which infect a variety of mammals as intermediate or accidental hosts including humans. Parasite transmission is based on domestic, semi-domestic and wildlife cycles; however, little is known of the epidemiological significance of wild large definitive hosts such as the wolf. In this study, 179 scats […]

Historic Facts When Wolves Are Over Protected

In response to an article presented on an activist website exclaiming the “victory” of when a United States federal judge, Beryl Howell, placed gray wolves back under government protection due to a self-perceived interpretation of the Endangered Species Act and disregard for existing laws, Will Graves offers a blunt reminder of global historic accounts of […]
