| granulomatous inflammation in retropharyngeal lymph nodes of wild cervids in saskatchewan. | a portion of retropharyngeal lymph nodes from 6,824 wild cervids, comprising 1,458 white-tailed deer (odocoileus virginianus), 5,345 mule deer (odocoileus hemionus), 11 unidentified deer (odocoileus spp.), and 10 elk (cervus elaphus), were examined histologically for evidence of inflammation. focal granulomatous lymphadenitis was detected in 0.3% of white-tailed deer, 1.3% of mule deer, and in one of 10 elk. material consistent with splendore-hoeppli phenomenon was present in 70 (93%) of 75 case ... | 2009 | 19617472 |
| babesia odocoilei infection in a saskatchewan elk (cervus elaphus canadensis) herd. | an 8-year-old female elk (cervus elaphus canadensis) cow, presented for chronic severe weight loss and unthriftiness, was diagnosed with babesia odocoilei infection based on blood smear evaluation, polymerase chain reaction (pcr), and dna sequence analysis. subsequently, velvet antler from a male that died acutely on the same farm was also pcr positive for babesia spp. both animals originated from a game ranch of saskatchewan-bred and -raised animals with no known history of tick exposure, but w ... | 2013 | 23780934 |
| epidemiology of an outbreak of chronic wasting disease on elk farms in saskatchewan. | an outbreak of chronic wasting disease (cwd) in farmed elk in saskatchewan from 1996 to 2002 was reviewed to 1, determine the progression of cwd from infection to death in farmed elk; 2, assess animal risk factors for cwd infection in farmed elk; 3, assess farm management and exposure risk factors for within herd cwd transmission; and 4, assess the suitability of the canadian food inspection agency's (cfia) current disease control policy for cwd in light of the findings. the results from animal ... | 2007 | 18189044 |
| the geography of conflict between elk and agricultural values in the cypress hills, canada. | complex ecological issues like depredation and its management are determined by multiple factors acting at more than one scale and are interlinked with complex human social and economic behaviour. depredation by wild herbivores can be a major obstacle to agricultural community support for wildlife conservation. for three decades, crop and fence damage, competition with livestock for native rangeland and tame pasture, and depredation of stored feed by elk (cervus elaphus canadensis) have been the ... | 2009 | 18082311 |
| intrapopulation variation in gray wolf isotope (delta(15)n and delta(13)c) profiles: implications for the ecology of individuals. | trophic relationships among organisms in terrestrial boreal ecosystems define ecological communities and are important in determining dynamics of energy flow and ecosystem function. we examined trophic relationships between the gray wolf (canis lupus) and 18 mammalian species from the boreal forest of central saskatchewan, canada, using delta(13)c and delta(15)n stable isotope values measured in guard hair samples. variance in isotope values for wolves and other carnivores was investigated as a ... | 2005 | 15883848 |
| the first canadian indigenous case of bovine spongiform encephalopathy (bse) has molecular characteristics for prion protein that are similar to those of bse in the united kingdom but differ from those of chronic wasting disease in captive elk and deer. | brain tissue from a case of bovine spongiform encephalopathy (bse) from alberta was subjected to a western immunoblotting technique to ascertain the molecular profile of any disease-specific, abnormal prion protein, that is, prion protein that is protease-resistant (prp(res)). this technique can discriminate between isolates from bse, ovine scrapie, and sheep experimentally infected with bse. isolates of brain tissue from the bse case in alberta, 3 farmed elk with chronic wasting disease (cwd) f ... | 2004 | 15532881 |
