viruses isolated from captive and free-ranging wild ruminants in alberta.nasal secretions, leukocytes and preputial or vaginal swabs from a group of 15 captive wild ruminants, comprising six pronghorn antelope (antilocapra americana), seven fallow deer (dama dama) and two mule deer (odocoileus hemionus), and from 50 free-ranging pronghorns in southern alberta, were examined for viral agents. captive animals were given injections of dexamethasone daily for 6 days in attempts to reactivate latent infections. specimens were collected at 2-3 day intervals from days 0 to ...1977190422
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
parelaphostrongylus odocoilei (nematoda: protostrongylidae) and a protostrongylid nematode in woodland caribou (rangifer tarandus caribou) of alberta, canada.two size-groups of dorsal-spined, first-stage, nematode larvae were found in feces of woodland caribou, rangifer tarandus caribou (gmelin), in alberta from 1976-1982. larvae from caribou feces in northeastern alberta were 451 +/- 17 micrograms in length, while those from west-central alberta were 362 +/- 18 micrograms in length. larvae collected from west-central alberta developed to the infective stage, experimentally, in the terrestrial gastropod triodopsis multilineata (say) and were infectiv ...19862869151
sarcocystis in wild ungulates in alberta.muscle samples from 557 wild ungulates in alberta, comprising seven species, were examined grossly and/or histologically for cysts of sarcocystis. sarcocystis was found in 100, 96, 94, 75, 75, 73, and 49% of the wapiti (cervus canadensis), moose (alces alces), bison (bison bison), mule deer (odocoileus hemionus), bighorn sheep (ovis canadensis), mountain goat (oreamnos americanus), and white-tailed deer (o. virginianus), respectively.19806780701
geographic distribution of the muscle-dwelling nematode parelaphostrongylus odocoilei in north america, using molecular identification of first-stage larvae.molecular identification of dorsal-spined larvae (dsl) from fecal samples indicates that the protostrongylid parasite parelaphostrongylus odocoilei occupies a broader geographic range in western north america than has been previously reported. we analyzed 2,124 fecal samples at 29 locations from thinhorn sheep (ovis dalli dalli and o. d. stonei), bighorn sheep (ovis canadensis canadensis and o. c. californiana), mountain goats (oreamnos americanus), woodland caribou (rangifer tarandus caribou), ...200516108550
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
polymorphisms at the prnp gene influence susceptibility to chronic wasting disease in two species of deer (odocoileus spp.) in western canada.chronic wasting disease (cwd) is increasingly prevalent in multiple wild mule (odocoileus hemionus) and white-tailed deer (o. virginianus) herds in north america. cwd was first found in canadian wild mule deer in saskatchewan in 2000 and has since spread into the neighboring province of alberta. the infectious agent for cwd is a misfolded prion protein encoded by the prnp gene. previous studies revealed association between prnp genotype and susceptibility to cwd in both mule and white-tailed dee ...200919697236
bovine tuberculosis in canadian wildlife: an updated history.mycobacterium bovis infection in wild animals attracted little attention in canada until the disease was almost eliminated from domestic livestock. tuberculosis was endemic in plains bison and occurred in elk, moose, and mule deer in buffalo national park (bnp), alberta during the 1920s and 1930s. bison were moved from bnp to wood buffalo national park (wbnp), where tuberculosis became, and remains, endemic in bison, posing a risk to efforts to restore bison in northern canada. tuberculosis was ...200920119541
deep mitochondrial dna lineage divergences within alberta populations of dermacentor albipictus (acari: ixodidae) do not indicate distinct species.the winter tick dermacentor albipictus (packard) has a single-host life cycle that allows it to reach severe infestation levels on ungulates, particularly moose. genotypic variation within these and related ticks has been a source of taxonomic confusion, although the continuity in their morphology and life history has generally been interpreted as indicating the existence of a single species. to further investigate this variation, we sequenced regions of two mitochondrial dna (mtdna) genes (coi ...201020695271
targeting the detection of chronic wasting disease using the hunter harvest during early phases of an outbreak in saskatchewan, canada.chronic wasting disease (cwd) is a fatal disease of north american cervids that was first detected in a wild, hunter-shot deer in saskatchewan along the border with alberta in canada in 2000. spatially explicit models for assessing factors affecting disease detection are needed to guide surveillance and control programs. spatio-temporal patterns in cwd prevalence can be complicated by variation in individual infection probability and sampling biases. we assessed hunter harvest data of mule deer ...201122137503

survey on 'lumpy jaw' on deer farms in western canada: prevalence and distribution, and identification of associated factors.to investigate the prevalence and geographical distribution of 'lumpy jaw' (lj) in a population of white-tailed deer (wtd; odocoileus virginianus) and mule deer (md; odocoileus hemionus) farms from the western canadian provinces of saskatchewan and alberta, and to identify factors associated with its occurrence.200717339914
dna typing in populations of mule deer for forensic use in the province of alberta.the present study involves the development of forensic dna typing tests and databases for mule deer in the province of alberta. two multiplex pcr reactions interrogating 10 loci were used to analyze samples from three populations of mule deer. additionally, an amelogenin based sex-typing marker was used to determine the gender of samples. results show that the tests and databases are appropriate for use in forensic applications. additionally, the results indicate that there is little population ...200819083820
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
