survey of hepatic and pulmonary helminths of wild cervids in alberta, canada.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 9 ...19902250321
diseases of wapiti utilizing cattle range in southwestern alberta.specimens from 28 wapiti (cervus elaphus canadensis) were collected by hunters in southwestern alberta in 1984. various tests were performed to detect infections and conditions that could affect cattle sharing the range or cause disease in wapiti. serum antibodies were present against leptospiral serovars autumnalis (25%), bratislava (4%), and icterohaemorrhagiae (8%), and the viruses of bovine virus diarrhea (52%), infectious bovine rhinotracheitis (45%), and parainfluenza type 3 (13%). no sero ...19873029443
an expanding population of the giant liver fluke (fascioloides magna) in elk (cervus canadensis) and other ungulates in canada.giant liver fluke (fascioloides magna) populations readily expand under suitable conditions. although extirpated from the eastern slopes of the canadian rocky mountains in the early 1960s, the fluke reappeared following natural spread through mountain passes from british columbia. herein, we assessed epizootiology of the fluke population two decades later. between 1984 and 1991, 534 ungulates, including 381 elk (cervus canadensis), 68 mule deer (odocoileus hemionus hemionus), 54 white-tailed dee ...201525647594
multiple origins of european populations of the giant liver fluke fascioloides magna (trematoda: fasciolidae), a liver parasite of ruminants.the giant liver fluke, fascioloides magna, a liver parasite of free-living and domestic ruminants of europe and north america, was analysed in order to determine the origin of european populations and to reveal the biogeography of this originally north american parasite on the european continent. the variable fragments of the mitochondrial cytochrome c oxidase subunit i (cox1; 384bp) and nicotinamide dehydrogenase subunit i (nad1; 405bp) were used. phylogenetic trees and haplotype networks were ...201021172350
survey of fascioloides magna in farmed wapiti in alberta.the formalin-ethyl acetate sedimentation procedure was used to detect ova of the giant liver fluke, fascioloides magna, in feces of farmed wapiti in alberta. twenty (3.2%) of the 629 fecal samples examined contained ova of f. magna. thirteen (33.3%) of the 39 farms surveyed had wapiti positive for f. magna. the presence of f. magna in farmed wapiti north of the north saskatchewan river is confirmed, and 3 areas where the infection has become endemic are identified.199910200881
an abattoir study of tuberculosis in a herd of farmed elk.the purpose of this study was to examine the prevalence and distribution of grossly visible lesions of tuberculosis in a herd of 344 north american elk (cervus elaphus) depopulated during a three-month period in 1991. abattoir inspection detected mycobacterial lesions in 134 (39.8%) of the 337 animals received for slaughter. the prevalence of lesions increased with the age of the animals. lesions were predominantly suppurative rather than caseous, and mineralization was less evident than in tube ...19947954222
