| feasibility of using coyotes (canis latrans) as sentinels for bovine mycobacteriosis (mycobacterium bovis) infection in wild cervids in and around riding mountain national park, manitoba, canada. | elk (cervus elaphus manitobensis) and white-tailed deer (odocoileus virginianus) in the riding mountain national park (rmnp) region of southwestern manitoba have been identified as a likely wildlife reservoir of mycobacterium bovis, the causative agent of bovine mycobacteriosis in livestock. the feasibility of using coyotes (canis latrans) collected from trappers as a sentinel species was investigated. retropharyngeal, mesenteric, and colonic lymph nodes and tonsils collected at necropsy from 82 ... | 2007 | 17699081 |
| bovine tuberculosis in canadian wildlife: an updated history. | mycobacterium bovis infection in wild animals attracted little attention in canada until the disease was almost eliminated from domestic livestock. tuberculosis was endemic in plains bison and occurred in elk, moose, and mule deer in buffalo national park (bnp), alberta during the 1920s and 1930s. bison were moved from bnp to wood buffalo national park (wbnp), where tuberculosis became, and remains, endemic in bison, posing a risk to efforts to restore bison in northern canada. tuberculosis was ... | 2009 | 20119541 |
| cadmium levels in ontario moose and deer in relation to soil sensitivity to acid precipitation. | this study examines the influence of buffering capacity of the soil on the levels of cadmium in the kidney, liver and muscle of moose and white-tailed deer from nine sampling sites (four buffered and five non-buffered) in ontario, canada. tissues collected from hunter-killed moose and deer during 1984 and 1985 were analysed for cadmium. tissue from moose in the non-buffered algonquin park site (21.9 +/- 1.1 mg/kg wet weight) and the buffered st. joseph island site (12.7 +/- 3.2 mg kg-1) had the ... | 1988 | 3381081 |
| distribution and ecology of meningeal worm, parelaphostrongylus tenuis (nematoda), in northcentral north america. | meningeal worm (parelaphostrongylus tenuis), a common nematode parasite in white-tailed deer (odocoileus virginianus) and pathogenic for several species of ungulates in eastern north america, is not known to occur in the west. heads of 1,902 white-tailed deer were examined for adult meningeal worm to determine geographic distribution of the parasite in saskatchewan and manitoba (canada) and north dakota (usa). finding the parasite in a deer in eastern saskatchewan near the manitoba border establ ... | 2003 | 12910761 |
| identification of dorsal-spined larvae from free-ranging wapiti (cervus elaphus) in southwestern manitoba, canada. | dorsal-spined first-stage larvae recovered from feces of free-ranging wapiti (cervus elaphus) were passaged through snails (triodopsis multilineata) and two hand-raised white-tailed deer fawns (odocoileus virginianus). a total of 74 adult parelaphostrongylus tenuis were recovered from the fawns; no other protostrongylid nematodes were recovered. the study indicates that wapiti may be infected with natural infections of meningeal worm and pass larvae suitable for transmission to gastropod interme ... | 1989 | 2716114 |
| alternative prey use affects helminth parasite infections in grey wolves. | predators affect prey populations not only through direct predation, but also by acting as definitive hosts for their parasites and completing parasite life cycles. understanding the affects of parasitism on prey population dynamics requires knowing how their predators' parasite community is affected by diet and prey availability. ungulates, such as moose (alces americanus) and white-tailed deer (odocoileus virginianus), are often important prey for wolves (canis lupus), but wolves also consume ... | 2016 | 27155132 |
| evaluating use of cattle winter feeding areas by elk and white-tailed deer: implications for managing bovine tuberculosis transmission risk from the ground up. | transmission of bovine tuberculosis (mycobacterium bovis) among wildlife and livestock has created important risks for conservation and agriculture. management strategies aimed at controlling tb have typically been top-down, regionally focused, and government-led programs that were at best only partially successful. the purpose of this study was to quantify co-mingling of elk and white-tailed deer (wtd) with cattle at multiple spatial scales (i.e., the regional farm scale and winter cattle feedi ... | 2013 | 22940061 |
| incorporating farmer observations in efforts to manage bovine tuberculosis using barrier fencing at the wildlife-livestock interface. | a federal and provincial cost-shared program was initiated in 2001 around riding mountain national park in southwestern manitoba, canada to provide free game wire barrier fences for baled hay storage areas to prevent transmission of tb among cattle (bos taurus), wild elk (cervus elaphus), and deer (odocoileus virginianus). farmer observations of cervids on their farms were evaluated by interviewing 50 farmers that owned a game wire fence for >1 year. of those interviewed, 82% reported some type ... | 2010 | 20129682 |
