Description

Two species of liver flukes have recently gained attention in Albertaís livestock and game farm industries. One species, the common liver fluke, Fasciola hepatica, has a wide range of herbivore hosts in which it can develop including cattle, bison, sheep, deer, swine and llama. In contrast, the giant liver fluke, Fascioloides magna, has a narrow host range. Wapiti (elk), white-tailed deer and caribou are the main hosts of this latter parasite in North America.
