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
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
a brief review of infectious and parasitic diseases of wapiti, with emphasis on western canada and the northwestern united this paper i review diseases reported in both captive and free-ranging wapiti in western north america, with some reference to diseases in captive red deer in great britain, europe, new zealand, and eastern north america.with the exception of coronavirus in neonates, few viral agents are reported to cause serious disease losses in wapiti in north america at this time. bacterial diseases of current significance include brucellosis (focus in wyoming), clostridial diseases, coliform enteritis of ...199117423839
epidemiological characteristics of an invading parasite: dicrocoelium dendriticum in sympatric wapiti and beef cattle in southern alberta, canada.previous surveys of wild ungulates indicate that the liver fluke, dicrocoelium dendriticum, was rare in the cypress hills area of southeastern alberta. however, 41 of 59 wapiti (cervus elaphus) sampled during the 2003 and 2004 hunting seasons from this region were infected, with 7 hosts containing >1,000 worms. prevalence and mean intensity were similarly high in sympatric beef cattle and mule deer. worm abundance in wapiti was age related, with calves containing significantly higher numbers of ...200717626339
characterization of nine microsatellite loci for dicrocoelium dendriticum, an emerging liver fluke of ungulates in north america, and their use to detect clonemates and random mating.this study characterizes polymorphic microsatellite loci from adults of the liver fluke dicrocoelium dendriticum sampled from a population of sympatric beef cattle and wapiti in a region of emergence in southern alberta, canada. we also scrutinized the markers to validate their use in studying the population genetics of this complex life cycle parasite. among the nine loci described, four deviated significantly from hardy weinberg equilibrium (hwe) due to technical artefacts. the remaining five ...201627188658
extension of occurrence area of the american fluke fascioloides magna in south-western poland.liver fluke fascioloides magna is a typical parasite of american cervids. the reason for f. magna to appear in poland territory was bringing the american wapiti deer to those forests around 1850. along with these deer the aforementioned fluke was also introduced. the aim of this study was to present the case of finding of this species in cervids in bory zielonogórskie. samples of deer feces were collected in february 2015 in forest district krzystkowice. a total of 16 samples of feces were exami ...201526342504
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
fascioloides magna: occurrence in saskatchewan and distribution in canada.infection with fascioloides magna, the large american liver fluke, was diagnosed in two moose (alces alces) and six wapiti (cervus elaphus) from central saskatchewan. this is believed to be the first record of the parasite in the province. fecal samples collected from wild wapiti at five sites in the commercial forest zone in saskatchewan contained eggs believed to be those of f. magna. trematode eggs were not found in feces from five captive herds of wapiti in the province, nor in samples from ...198517422561
molecular identification of fascioloides magna (bassi, 1875) from red deer from south-western poland (lower silesian wilderness) on the basis of internal transcribed spacer 2 (its-2).the study was conducted in 2012-2013 on 75 fecal samples of red deer from the lower silesian wilderness which were examined to determine the prevalence of fascioloides magna in the game population. finding liver fluke eggs in a single sample which were larger in size than fasciola hepatica eggs indicated that further molecular analysis was necessarily. the partial sequence (116 bp long) of its-2 of the investigated eggs was identical to the sequences of f. magna from red deer (cervus elaphus) (g ...201425286665
