Wolves in Colville Valley worry state wildlife managers

*Staff Note* – Apparently missing from this information are two important facts. One, that dogs and wolves mixing this readily is a sure recipe for cross breeding between dogs and wolves – a sure destruction of the wolf gene. Second, wolves are carriers of disease, specifically Echinococcus granulosus worms, Neospora Caninum, and others. Wolves inhabiting […]

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 […]

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 […]

Letter: Will N. Graves to USFWS Wolf-Carried Diseases – October 3, 1993

1. Diseases, Worms, and Parasites. I was surprised that the DEIS (Draft Environmental Impact Statement) did not make a detailed study on the impact issue of diseases, worms, and parasites (page 9). I believe an EIS is not complete without a detailed study covering the diseases, worms and parasites that wolves would carry, harbor, and […]

Coyotes (Canis latrans) are definitive hosts of Neospora caninum

Abstract Four captive-raised coyote pups consumed tissues from Neospora caninum-infected calves. Faeces were examined from 4 days before to 28 days after infection. One pup shed N. caninum-like oocysts, which tested positive for N. caninum and negative for Hammondia heydorni using PCR tests. Coyotes are the second discovered definitive host of N. caninum, after dogs. […]

A Serological Survey of Infectious Disease in Yellowstone National Park’s Canid Community

Emily S. Almberg, L. David Mech, Douglas W. Smith, Jennifer W. Sheldon, Robert L. Crabtree Abstract Background: Gray wolves (Canis lupus) were reintroduced into Yellowstone National Park (YNP) after a .70 year absence, and as part of recovery efforts, the population has been closely monitored. In 1999 and 2005, pup survival was significantly reduced, suggestive […]

Neospora caninum is heartbreaker for cow/calf operators

A protozoan parasite that causes spontaneous abortions, stillborn calves and premature births in cattle is a growing concern in northern Minnesota. Neospora caninum (ka-ni-num) can enter a cowherd when wolves, coyotes, fox or dogs feed on placenta, dead calves or deer that contain the parasite. When the canines defecate, the parasite egg is transferred to […]

Overview of Neosporosis

This report made available through Merck Neospora caninum is a microscopic protozoan parasite with worldwide distribution. Many domestic (eg, dogs, cattle, sheep, goats, water buffalo, horses, chickens) and wild and captive animals (eg, deer, rhinoceros, rodents, rabbits, coyotes, wolves, foxes) can be infected. Neosporosis is one of the most common causes of bovine abortion, especially […]

Gray wolf (Canis lupus) is a natural definitive host for Neospora caninum

J.P. Dubey, M.C. Jenkins, C. Rajendran, K. Miska, L.R. Ferreira, J. Martins, O.C.H. Kwok, S. Choudhary Abstract The gray wolf (Canis lupus) was found to be a new natural definitive host for Neospora caninum. Neospora-like oocysts were found microscopically in the feces of three of 73 wolves from Minnesota examined at necropsy. N. caninum-specific DNA […]
