observations on epizootiology and distribution of elaeophora schneideri in montana ruminants.seventy-four moose, 111 elk, 20 mule deer, 8 white-tailed deer, 26 prong-horn antelope, 42 domestic sheep and 3 bighorn sheep from montana or northwestern wyoming were examined post-mortem for evidence of elaeophora schneideri infection in 1973-74. fifteen percent of the mule deer and four percent of the moose were positive for adult arterial worms. this constitutes the first report of e. schneideri in mule deer in montana. no gross signs of blindness or other neurologic disorder were evident in ...1975127848
eimeria ivensae sp. n. from the mule deer, odocoileus hemionus hemionus, in montana. 19695372089
epizootic hemorrhagic disease virus in montana: isolation and serologic survey.epizootic hemorrhagic disease virus (ehdv) was isolated in vero cell culture from the spleen and whole blood of a white-tailed deer (odocoileus virginianus). a 10% spleen suspension caused acute hemorrhagic disease (hd) when inoculated into an experimental white-tailed deer and resulted in the recovery of ehdv from the blood of the experimental animal at 5 days after inoculation. the virus was identified as ehdv serotype 2 through indirect fluorescent antibody tests, electron microscopy, and rec ...19816267969
isolation of encysted toxoplasma gondii from muscles of mule deer in montana.toxoplasma gondii was isolated from muscles of 2 road-killed mule deer found near bozeman, mont, by feeding muscles to a toxoplasma-free cat. the cat shed t gondii oocysts 5 days after ingesting muscles pooled from the 2 deer. one infective oocyst of this isolate of t gondii was lethal to mice.19827161172
isolation of encysted toxoplasma gondii from musculature of moose and pronghorn in montana.pieces of skeletal muscle from 43 mule deer, 34 elk, 4 white-tailed deer, 21 pronghorn, 7 moose, and 2 bison were examined for toxoplasma infection, by the acid-pepsin digestion technique. toxoplasma gondii was isolated from 1 moose and 1 pronghorn. the isolated strains of t gondii were of low virulence to mice.19817224306
bovine tuberculosis in a free-ranging mule deer (odocoileus hemionus) from montana.a survey of 41 mule deer (odocoileus hemionus) and three white-tailed deer (o. virginianus) for bovine tuberculosis was conducted on a montana (usa) cattle ranch from 2 november 1993 through january 1994. gross and microscopic lesions typical of tuberculosis were present in tonsil and lymph nodes of the head, thorax, and abdomen of one adult female mule deer. additionally, a single microgranuloma considered morphologically suggestive of tuberculosis was present in one lymph node of the head of a ...19958592372
sequence analysis of the msp4 gene of anaplasma ovis strains.anaplasma ovis (rickettsiales: anaplasmataceae) is a tick-borne pathogen of sheep, goats and wild ruminants. the genetic diversity of a. ovis strains has not been well characterized due to the lack of sequence information. in this study, we evaluated bighorn sheep (ovis canadensis) and mule deer (odocoileus hemionus) from montana for infection with a. ovis by serology and sequence analysis of the msp4 gene. antibodies to anaplasma spp. were detected in 37% and 39% of bighorn sheep and mule deer ...200717052866
echinococcus granulosus in gray wolves and ungulates in idaho and montana, usa.we evaluated the small intestines of 123 gray wolves (canis lupus) that were collected from idaho, usa (n=63), and montana, usa (n=60), between 2006 and 2008 for the tapeworm echinococcus granulosus. the tapeworm was detected in 39 of 63 wolves (62%) in idaho, usa, and 38 of 60 wolves (63%) in montana, usa. the detection of thousands of tapeworms per wolf was a common finding. in idaho, usa, hydatid cysts, the intermediate form of e. granulosus, were detected in elk (cervus elaphus), mule deer ( ...200919901399
the population history of endogenous retroviruses in mule deer (odocoileus hemionus).mobile elements are powerful agents of genomic evolution and can be exceptionally informative markers for investigating species and population-level evolutionary history. while several studies have utilized retrotransposon-based insertional polymorphisms to resolve phylogenies, few population studies exist outside of humans. endogenous retroviruses are ltr-retrotransposons derived from retroviruses that have become stably integrated in the host genome during past infections and transmitted verti ...201724336966
spatial heterogeneity of mitochondrial dna and allozymes among populations of white-tailed deer and mule deer.a white-tailed deer (odocoileus virginianus) population in northeastern minnesota and a mule deer (o. hemionus) population in the bridger mountains montana, have previously been shown to be spatially subdivided into contiguous subpopulations. we assessed the degree of genetic differentiation among subpopulations and tested the hypothesis that differentiation will be greater for mitochondrial dna (mtdna) than for nuclear-encoded allozymes. differentiation of the white-tailed deer subpopulations w ...20071849522
sarcocystis infections in mule deer (odocoileus hemionus) in montana and the descriptions of three new species.four structural types of sarcocysts of sarcocystis were found in skeletal muscles of mule deer in montana. type i sarcocysts were thin walled (1 to 3 micron) and belonged to s hemionilatrantis. types ii to iv sarcocysts were thick walled (2 to 10 microns) and new names were proposed for them. type ii sarcocysts with long villar projections were named s hemioni. type iii sarcocysts with club-shaped villi of uneven thickness were named s youngi. type iv sarcocysts with walls of uneven thickness an ...19863087246
prevalence and ultrastructure of three types of sarcocystis in mule deer, odocoileus hemionus (rafinesque), in montana.infection with sarcocystis (protozoa: sarcocystidae) was diagnosed in 130 of 153 (85%) samples of muscle from mule deer around bozeman, montana. three structurally distinct mature and microscopic sarcocysts with characteristic cyst walls were found. cyst walls of type i sarcocysts were about 2 microns thick and had characteristic inverted tee-shaped villar projections; these cysts were considered to be s. hemionilatrantis hudkins and kistner, 1976. cyst walls in type ii sarcocysts were thick-wal ...19853928909
