| 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 ... | 1975 | 127848 |
| 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 ... | 1981 | 6267969 |
| sarcocystis infection in the white-tailed deer (odocoileus virginianus) in montana: intensity and description of sarcocystis odoi n sp. | sarcocystis infection was diagnosed in 27 of 36 (75%) samples of meat from white-tailed deer (odocoileus virginianus) in montana. two structurally distinct thin- and thick-walled sarcocysts were found in the white-tailed deer; the thin-walled sarcocysts were those of s odocoileocanis. a new name, s odoi, was proposed for the thick-walled sarcocysts. sarcocysts of s odoi were up to 1,050 microns long and 260 microns wide and contained a 6.5- to 12-microns thick wall. the ultrastructure of sarcocy ... | 1983 | 6414349 |
| 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. | 1981 | 7224306 |
| 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 ... | 1995 | 8592372 |
| evaluation of methods for collecting blood-engorged mosquitoes from habitats within a wildlife refuge. | mortality of american white pelican (pelecanus erythrorhynchos) chicks attributed to west nile virus (wnv) prompted field studies on the bionomics of mosquitoes on a wildlife refuge in northern montana. one component of these studies was to identify blood meal sources for culex tarsalis, the primary vector of wnv in the region, and the potential bridge vectors aedes vexans and culiseta inornata. to accomplish this, 3 methods were evaluated to collect bloodfed mosquitoes: a gasoline powered aspir ... | 2013 | 23923324 |
| morphology, prevalence, and distribution of sarcocystis spp. in white-tailed deer (odocoileus virginianus) from florida. | three morphologically distinct types of sarcocysts (i, ii, and iii) were identified by light microscopy in tongues from 403 white-tailed deer (odocoileus virginianus) collected in florida (usa) over a 7-yr-period. based on electron microscopy of representative examples of these sarcocysts, there were four distinctive wall structures. we concluded that one of these (type i) was representative of sarcocystis odocoileocanis and another (type iii) was representative of an unnamed species previously ... | 1993 | 8445792 |
| 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 ... | 2017 | 24336966 |
| 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 ... | 2007 | 1849522 |
