title: Survey of hepatic and pulmonary helminths of wild cervids in Alberta, Canada.
abstract: During the 1988 hunting season, livers and lungs from 263 mule deer (Odocoileus hemionus hemionus), 198 moose (Alces alces), 147 white-tailed deer (Odocoileus virginianus), and 94 wapiti (Cervus elaphus nelsoni) from Alberta (Canada) were collected for parasitological examination. Most of the samples (89%) were submitted by big game hunters throughout the province. Giant liver fluke (Fascioloides magna) was found in 9% of 22 yearling and 29% of 65 adult wapiti; 4% of 161 adult moose; and 2% of 97 adult white-tailed deer. The intensity of infection generally was low; however, one wapiti had over 600 flukes in the liver. Infections were restricted to alpine and montane regions in southwestern Alberta (97%) as well as boreal uplands of the Cypress Hills in southeastern Alberta (3%). Other parasites recorded included Taenia hydatigena cysts in liver of 61% of 191 moose and 14% of 247 mule deer. Dictyocaulus viviparus was found in lungs of 14% of 50 moose, 14% of 118 mule deer, 12% of 41 wapiti, and 6% of 54 white-tailed deer. Echinococcus granulosus cysts were found in lungs (and occasionally liver) of 37% of 51 moose. Incidental infections of Thysanosoma actinoides, Orthostrongylus macrotis, and Taenia omissa were recorded. Adult Dicrocoelium dendriticum were collected from liver of two wapiti, one mule deer, and one white-tailed deer from the Cypress Hills.
