| geographic distribution of the muscle-dwelling nematode parelaphostrongylus odocoilei in north america, using molecular identification of first-stage larvae. | molecular identification of dorsal-spined larvae (dsl) from fecal samples indicates that the protostrongylid parasite parelaphostrongylus odocoilei occupies a broader geographic range in western north america than has been previously reported. we analyzed 2,124 fecal samples at 29 locations from thinhorn sheep (ovis dalli dalli and o. d. stonei), bighorn sheep (ovis canadensis canadensis and o. c. californiana), mountain goats (oreamnos americanus), woodland caribou (rangifer tarandus caribou), ... | 2005 | 16108550 |
| bovicola tibialis (phthiraptera:trichodectidae): occurrence of an exotic chewing louse on cervids in north america. | through a recent (2003-2007) survey of ectoparasites on hoofed mammals in western north america, a literature review, and examination of archived museum specimens, we found that the exotic deer-chewing louse, bovicola tibialis (piaget), is a long-term, widespread resident in the region. the earliest known collection was from salt spring island, canada, in 1941. we found these lice on the typical host, that is, introduced european fallow deer (dama dama l.), and on asian chital (axis axis [erxleb ... | 2011 | 21337942 |
| Molecular Study of Free-ranging Mule Deer and White-tailed Deer from British Columbia, Canada, for Evidence of Anaplasma spp. and Ehrlichia spp. | Twenty-three free-ranging white-tailed deer (WTD; Odocoileus virginianus) and six mule deer (MD; Odocoileus hemionus) from south-central British Columbia, Canada, were tested for Anaplasma marginale by msp5 gene-specific PCR and Ehrlichia spp. by 16S rRNA or citrate synthase (gltA) gene-specific PCR, as well as by PCR with universal 16S rRNA primers detecting a wide range of bacteria. No deer tested positive for A. marginale. Amplification with universal 16S rRNA primers followed by sequencing o ... | 2011 | 21933360 |
| an expanding population of the giant liver fluke (fascioloides magna) in elk (cervus canadensis) and other ungulates in canada. | giant liver fluke (fascioloides magna) populations readily expand under suitable conditions. although extirpated from the eastern slopes of the canadian rocky mountains in the early 1960s, the fluke reappeared following natural spread through mountain passes from british columbia. herein, we assessed epizootiology of the fluke population two decades later. between 1984 and 1991, 534 ungulates, including 381 elk (cervus canadensis), 68 mule deer (odocoileus hemionus hemionus), 54 white-tailed dee ... | 2015 | 25647594 |
| capture of free-ranging mule deer (odocoileus hemionus) with a combination of medetomidine, azaperone, and alfaxalone. | the combination of medetomidine, azaperone, and alfaxalone has been successfully used to anesthetize captive white-tailed deer ( odocoileus virginianus ). this same combination was utilized to immobilize free-ranging female mule deer ( odocoileus hemionus ; md) in urban and nonurban environments (14 urban md, 14 nonurban md) in british columbia, canada. physiologic data were collected to assess the safety and reliability of this drug combination under field conditions. each deer received estimat ... | 2017 | 28151080 |
