| immunohistochemical diagnosis of chronic wasting disease in preclinically affected elk from a captive herd. | an immunohistochemical (ihc) method was used to test brain tissues from 17 elk in a captive herd in which chronic wasting disease (cwd) had previously occurred. the ihc technique detects the protease-resistant prion protein (prp-res), which is considered a disease-specific marker for transmissible spongiform encephalopathies (tse), regardless of the species affected. of the 17 elk tested, 10 were positive by ihc. only 2 of these 10 animals had shown clinical signs and histologic lesions of cwd, ... | 2000 | 11108464 |
| microsatellite variation in the reintroduced pennsylvania elk herd. | relocation programs have restored elk (cervus elaphus) to portions of its vast historical range. we examine the consequences of these relocation programs by assessing variation at 10 microsatellite loci in three elk herds, a source herd (yellowstone national park), a large herd reintroduced from yellowstone (custer state park) and a bottlenecked herd reintroduced from both yellowstone and custer (the pennsylvania herd). observed single locus heterozygosities ranged from 0.000 to 0.739. multi-loc ... | 2002 | 12144652 |
| 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 ... | 2003 | 12685066 |
| 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 ... | 2004 | 15137501 |
| 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 ... | 2010 | 20688655 |
