The helminths of wolves and coyotes from the forested regions of Alberta
Ninety-eight wolves and 75 coyotes from the forested regions of Alberta were examined for helminths. Fourteen species (2 trematodes, 8 cestodes, and 4 nematodes) were recovered from wolves, with a mean of 2.6 and a maximum of 6 species per wolf; 18 species (3 trematodes, 8 cestodes, and 7 nematodes)...
