Severe hoof disease in free-ranging Roosevelt elk (Cervus elaphus roosevelti) in southwestern Washington, USA.
Reports of free-ranging Roosevelt elk (Cervus elaphus roosevelti) with abnormal hooves and lameness increased significantly in southwestern Washington, USA, during winter 2008. In March 2009 we examined five severely affected elk with clinical lameness from this region to characterize hoof lesions, examine the general health of affected elk, and potentially identify etiologies causing hoof dise...
متن کاملProbable causes of increasing brucellosis in free-ranging elk of the Greater Yellowstone Ecosystem.
While many wildlife species are threatened, some populations have recovered from previous overexploitation, and data linking these population increases with disease dynamics are limited. We present data suggesting that free-ranging elk (Cervus elaphus) are a maintenance host for Brucella abortus in new areas of the Greater Yellowstone Ecosystem (GYE). Brucellosis seroprevalence in free-ranging ...
متن کاملPathogen-mediated selection in free-ranging elk populations infected by chronic wasting disease.
Pathogens can exert a large influence on the evolution of hosts via selection for alleles or genotypes that moderate pathogen virulence. Inconsistent interactions between parasites and the host genome, such as those resulting from genetic linkages and environmental stochasticity, have largely prevented observation of this process in wildlife species. We examined the prion protein gene (PRNP) in...
متن کاملPrevalence 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 (Cervu...
متن کاملEffects of GonaCon Immunocontraceptive Vaccine in Free-Ranging Female Rocky Mountain elk (<i>Cervus elaphus nelsoni</i>)
Duration of efficacy and prevalence of side-effects associated with GonaCon Immunocontraceptive Vaccine (GonaCon) in free-ranging female elk (Cervus elaphus) are unknown. In January 2008, we captured 120mature female elk in RockyMountain National Park (CO, USA), determined pregnancy status, and randomly assigned them to treated (n1⁄4 60; 1.5mL of GonaCon) or control (n1⁄4 60; 1.5mL of saline) g...
