necropsy and laboratory findings in free-living deer in south a diagnostic survey of diseases in wild white-tailed deer (62 cases) and mule deer (12 cases) the most common findings were traumatic injury (20%), nontraumatic hemorrhage (13%), polioencephalomalacia (11%), and bacterial infections (9%). although epizootic hemorrhagic disease was suspected in several cases, the virus was isolated from only 1 white-tailed deer.1976185186
sarcocystis of deer in south dakota.the prevalence of sarcocystis in white-tailed deer (odocoileus virginianus) and mule deer (o. hemionus) in south dakota was determined through microscopic examination of tongue samples. the percentage of sarcocystis infection for both species of deer was determined for prairies east of the missouri river, west of the missouri river, and black hills of western south dakota. sixteen percent (n = 62) of the white-tailed deer tongues from east river, 69% (n = 42) from west river, and 74% (n = 23) fr ...19826808161
prevalence of chronic wasting disease and bovine tuberculosis in free-ranging deer and elk in south dakota.heads of hunter-harvested deer and elk were collected throughout south dakota (usa) and within established chronic wasting disease (cwd) surveillance areas from 1997-2002 to determine infection with cwd and bovine tuberculosis (tb). we used immunohistochemistry to detect cwd-infected individuals among 1,672 deer and elk sampled via geographically targeted surveillance. a total of 537 elk (cervus elaphus nelsoni), 813 white-tailed deer (odocoileus virginianus), and 322 mule deer (o. hemionus) was ...200312685066
distribution of meningeal worm (parelaphostrongylus tenuis) in south dakota.heads of hunter-harvested deer (odocoileus sp.) and elk (cervus elaphus) were collected from meat processing plants throughout south dakota (usa) from 1997 through 1999 to determine distribution of meningeal worm (parelaphostrongylus tenuis) in eastern and western south dakota. a total of 2,848 white-tailed deer (wtd) were examined for p. tenuis, of which 578 (20.3%) were infected with the parasite. of 578 deer infected, 570 (98.6%) were harvested east of the missouri river. our results indicate ...200415137501
new records of hair follicle mites (demodecidae) from north american cervidae.individuals of three species of cervids, with varying degrees of alopecia, were examined for ectoparasites: rocky mountain elk (cervus elaphus nelsoni) and mule deer (odocoileus hemionus hemionus) in colorado and white-tailed deer (odocoileus virginianus) in south dakota. hair follicle mites were recovered and identified as demodex kutzeri, a species originally described from the european red deer (cervus elaphus, from austria) and the sika deer (cervus nippon pseudaxis, captive in germany). the ...201020688655
synlophe in ostertagia cf. kasakhstanica (nematoda: ostertagiinae), the minor morphotype of o. bisonis from western north america.ostertagia cf. kasakhstanica, the putative minor morphotype of the polymorphic ostertagiine o. bisonis, is reported in bison bison from south dakota. descriptions of the synlophe and details of other diagnostic characters useful in identification and differentiation of this minor morphotype from other ostertagiines in wild and domestic ruminants from western north america are presented. laterally, the cervical synlophe is consistent with type ib pattern among ostertagiines and is within the rang ...200111695392
tonsillar biopsy test for chronic wasting disease: two sampling approaches in mule deer and white-tailed deer.preclinical antemortem testing of deer (odocoileus spp.) for chronic wasting disease (cwd) can be important for determining prevalence rates and removing infected individuals from wild populations. because samples with high numbers of tonsillar follicles are likely to provide earlier detection of cwd than samples with fewer follicles, the method of obtaining follicular samples may be critical when investigating disease prevalence. between january 2003 and january 2005, white-tailed deer (o. virg ...200516456177
hepatic minerals of white-tailed and mule deer in the southern black hills, south dakota.because there is a paucity of information on the mineral requirements of free-ranging deer, data are needed from clinically healthy deer to provide a basis for the diagnosis of mineral deficiencies. to our knowledge, no reports are available on baseline hepatic mineral concentrations from sympatric white-tailed deer (odocoileus virginianus) and mule deer (odocoileus hemionus) using different habitats in the northern great plains. we assessed variation in hepatic minerals of female white-tailed d ...200818436666
re-evaluating neonatal-age models for ungulates: does model choice affect survival estimates?new-hoof growth is regarded as the most reliable metric for predicting age of newborn ungulates, but variation in estimated age among hoof-growth equations that have been developed may affect estimates of survival in staggered-entry models. we used known-age newborns to evaluate variation in age estimates among existing hoof-growth equations and to determine the consequences of that variation on survival estimates. during 2001-2009, we captured and radiocollared 174 newborn (≤24-hrs old) ungulat ...201425264612
