demodicosis in a mule deer (odocoileus hemionus hemionus) from saskatchewan, canada.infestation of deer with demodex spp. mites has been described in white-tailed deer (odocoileus virginianus) and in columbian black-tailed deer (odocoileus hemionus columbianus) in north america, as well as in four species of deer in europe. we describe demodex sp. infestation in an adult female mule deer (odocoileus hemionus hemionus) with skin lesions found dead near saskatoon, saskatchewan, canada. this is believed to be the first report of demodicosis in mule deer.200717984276
polymorphisms at the prnp gene influence susceptibility to chronic wasting disease in two species of deer (odocoileus spp.) in western canada.chronic wasting disease (cwd) is increasingly prevalent in multiple wild mule (odocoileus hemionus) and white-tailed deer (o. virginianus) herds in north america. cwd was first found in canadian wild mule deer in saskatchewan in 2000 and has since spread into the neighboring province of alberta. the infectious agent for cwd is a misfolded prion protein encoded by the prnp gene. previous studies revealed association between prnp genotype and susceptibility to cwd in both mule and white-tailed dee ...200919697236
targeting the detection of chronic wasting disease using the hunter harvest during early phases of an outbreak in saskatchewan, canada.chronic wasting disease (cwd) is a fatal disease of north american cervids that was first detected in a wild, hunter-shot deer in saskatchewan along the border with alberta in canada in 2000. spatially explicit models for assessing factors affecting disease detection are needed to guide surveillance and control programs. spatio-temporal patterns in cwd prevalence can be complicated by variation in individual infection probability and sampling biases. we assessed hunter harvest data of mule deer ...201122137503
infectious disease and grouping patterns in mule deer.infectious disease dynamics are determined, to a great extent, by the social structure of the host. we evaluated sociality, or the tendency to form groups, in rocky mountain mule deer (odocoileus hemionus hemionus) from a chronic wasting disease (cwd) endemic area in saskatchewan, canada, to better understand factors that may affect disease transmission. using group size data collected on 365 radio-collared mule deer (2008-2013), we built a generalized linear mixed model (glmm) to evaluate wheth ...201627007808
survey on 'lumpy jaw' on deer farms in western canada: prevalence and distribution, and identification of associated investigate the prevalence and geographical distribution of 'lumpy jaw' (lj) in a population of white-tailed deer (wtd; odocoileus virginianus) and mule deer (md; odocoileus hemionus) farms from the western canadian provinces of saskatchewan and alberta, and to identify factors associated with its occurrence.200717339914
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 ...200919617472
