Pathology Case of the Month
Science Center Objects
Notable cases at the National Wildlife Health Center are highlighted here in the Pathology Case of the Month Series.
Wildlife pathologists at the National Wildlife Health Center routinely investigate the causes of wildlife mortality events in the United States as part of our diagnostic services. The pathologists examine carcasses to verify species and condition, collect and process photographic and radiographic images, conduct detailed necropsies, collect appropriate samples for histological preparation, and collect and submit appropriate tissue samples for diagnostic laboratory evaluation. Necropsy findings, histopathology, and laboratory test results are interpreted by pathologists to infer cause of death.
