Shelby Jo Weidenkopf Barbara L. Bodenstein 2025 <p>The U.S. Geological Survey National Wildlife Health Center provides diagnostic services to determine causes of wildlife morbidity and mortality events to State, Federal, and Tribal partners. To accomplish this, we rely on the timely collection and evaluation of submitted carcasses and the epidemiologic information relayed from personnel in the field. Our current submission criteria can be found here: <a href="https://www.usgs.gov/centers/nwhc/science/" data-mce-href="https://www.usgs.gov/centers/nwhc/science/">https://www.usgs.gov/centers/nwhc/science/</a> diagnostic-case-submission-guidelines. If the majority of carcasses found in the field are unsuitable for submission, then sick animals (birds, mammals, reptiles) that have been euthanized are acceptable specimens. Depending on the agency or affiliated institution, there may be additional requirements for submission. When applicable, always consult the organization’s wildlife health or veterinary staff.</p> application/pdf 10.3133/fs20253024 en U.S. Geological Survey Diagnostic success—A quick guide to quality carcass submissions for diagnostic services reports
