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

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.

In this study, 179 scats […]

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. […]

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.
