Expanding Distribution of Chronic Wasting Disease
Chronic wasting disease (CWD) has been detected in 33 US states and five Canadian provinces in free-ranging cervids and/or commercial captive cervid facilities. CWD has been detected in free-ranging cervids in 33 states and four provinces and in captive cervid facilities in 19 states and three provinces.
Application of a systems approach for management of chronic wasting disease
The USGS National Wildlife Health Center, Montana Cooperative Wildlife Research Unit, Ventana Systems, Inc. , and the Wisconsin Department of Natural Resources (WIDNR) are applying a systems approach to map and model the complex relationships among ecological, epidemiological, social, and political processes affecting CWD. Through a participatory modeling process, we gathered subject matter...
Examining PRNP gene frequencies and ‘resistance’ to chronic wasting disease
Multiple studies have demonstrated that various alleles of the cervid prion protein (PRNP) gene affect chronic wasting disease (CWD) progression.
Enhanced Capacity for Chronic Wasting Disease Research and Certified Diagnostics at the USGS National Wildlife Health Center
Chronic wasting disease (CWD) is a fatal disease that impacts populations of deer, elk, moose, and other cervid species caused by an infectious protein called a prion.
Assessing the Ability of Incineration to Inactivate CWD Prions from Carcasses
Chronic wasting disease (CWD), a fatal neurologic disease of cervids, presents a monumental management challenge, in part because the etiological agent, an infectious prion, is extremely difficult to inactivate and can be transmitted directly or indirectly to hosts. Due to these attributes of prions, proper disposal of CWD-infected carcasses is an important consideration for management agencies to...
Advancing the Use of RT-QuIC for Applications in CWD Management
Chronic wasting disease (CWD) is an emerging infectious disease that is fatal to free-ranging and captive animals in Cervidae, the deer family. The development of the real-time quaking-induced conversion (RT-QuIC) assay has the potential to transform laboratory research of prions and provide new opportunities for improved surveillance and management.
Chronic Wasting Disease
Chronic wasting disease (CWD) is an emerging infectious disease that is fatal to free-ranging and captive animals in Cervidae, the deer family. CWD is one member of a family of diseases called transmissible spongiform encephalopathies (TSEs), and is thought to be caused by prions. CWD is the only TSE known to affect free-ranging wildlife.
