In-Service Education And The Provision Of Educational Materials To Improve Awareness Of Chronic Wasting Disease Management Efforts In Arkansas, Mary Claire Stewart
In-Service Education And The Provision Of Educational Materials To Improve Awareness Of Chronic Wasting Disease Management Efforts In Arkansas, Mary Claire Stewart
Animal Science Undergraduate Honors Theses
Chronic Wasting Disease (CWD) is a disease caused by an accumulation of misfolded prions throughout the nervous system. This disease affects animals within the Cervidae Family, which includes deer, elk, moose, and caribou. This disease is fatal and physical symptoms often do not materialize until the animal is near death. CWD has become an increasing issue in Arkansas since an elk (Cervus canadensis) in Newton County tested positive for CWD in 2016. Since then, the Arkansas Game and Fish Commission (AGFC) has worked with the University of Arkansas Division of Agriculture (UADA) and others to develop management strategies to slow …

Host contact structure affects pathogen transmission in host populations, but many measures of host contact do not distinguish contacts that are relevant to pathogen transmission from those that are not. Scrapes are sites for chemical communication by white-tailed deer (Odocoileus virginianus) during the breeding season and potential sites of transmission of prions, the causative agent of chronic wasting disease (CWD). Scrape-related behaviors vary in their probability of transmitting prions to or from the environment, suggesting that behavior be combined with contact structure to better reflect potential heterogeneity in prion transmission at scrapes. We recorded visits and behaviors by …
Distribution Of The Misfolded Isoform Of The Prion Protein In Peripheral Tissues And Spinal Cord Of Rocky Mountain Elk (Cervus Elaphus Nelsoni) With Naturally Occurring Chronic Wasting Disease, Terry R. Spraker, Thomas Gidlewski, J. G. Powers, T. A. Nichols, M. A. Wild

Chronic wasting disease (CWD) is an infectious transmissible spongiform encephalopathy of cervids associated with the presence of a misfolded prion protein (PrPCWD). Progression of PrPCWD distribution has been described using immunohistochemistry and histologic changes in a single section of brain stem at the level of the obex resulting in scores from 0 (early) to 10 (terminal) in elk with naturally occurring CWD. Here we describe the spread and distribution of PrPCWD in peripheral tissues and spinal cord in 16 wild and 17 farmed Rocky Mountain elk (Cervus elaphus nelsoni) with naturally occurring CWD and correlate these findings with obex scores. …
