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.
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...
Research to understand SARS-CoV-2 risks for wildlife
Multiple research endeavors at the USGS National Wildlife Health Center are ongoing to help assess the possible impacts of SARS-CoV-2 on wildlife.
Can we transition to actionable surveillance for wildlife health: A workshop summary
New study describes HPAI infections in wild mammals in US
Highly pathogenic avian influenza H5N1 virus (HPAIv) has been present in North America since its first detection in wild birds in November 2021 (Newfoundland and Labrador, Canada), and has subsequently spread across the Americas.
White-nose syndrome vaccine updates
Since its emergence in 2006, white-nose syndrome (WNS) continues to spread in North America and has substantially impacted hibernating bat populations, contributing to declines of over 90% in northern long-eared (Myotis septentrionalis), little brown (Myotis lucifugus), and tri-colored bat (Perimyotis subflavus) populations. We are developing tools and management strategies to protect bat...
Planning underway for next phase of WHISPers development
Development planning is underway for the next phase of WHISPers (Wildlife Health Information Sharing Partnership – event reporting system).
