Hemangiosarcoma associated with a Pasteurella multocida infection in a near threatened cinereous vulture (Aegypius monachus): insights into avian pathology and implications for conservation

This case illustrates the complex interplay between neoplasia and bacterial infection in avian species and underscores the importance of multidisciplinary diagnostics in wildlife disease surveillance. Based on the clinical course and pathological findings, the most likely cause of death was acute septicemia with septic encephalopathy secondary to pulmonary hemangiosarcoma and concurrent Pasteurella multocida infection. Enhanced awareness of neoplastic conditions in Near Threatened scavenger birds is essential for effective conservation and rehabilitation strategies.
