Study details disease burden in confiscated birds and reptiles
CURRENT BRIEF VERSION: A postmortem study from Spain found that confiscated CITES-listed birds and reptiles housed in a CITES-authorized rescue center faced a heavy burden of infectious and metabolic disease, underscoring how wildlife trafficking can quickly become a veterinary management problem after animals are seized. The work, presented at the 2025 ESVP-ECVP congress by researchers from Complutense University of Madrid, Fundación FIEB, and TRAGSATEC, reviewed 29 deaths between 2021 and 2024: 17 birds across 12 species and 12 reptiles across 9 species. In birds, 52% of deaths were linked to infectious disease, while in reptiles, 50% were tied to metabolic or nutritional disease and 41% to infections. Common findings included enteritis, hepatitis, and renal gout in birds, and hepatocellular atrophy, biliary stasis, and renal gout in reptiles; bacterial infections were seen in both groups, and avian polyomavirus, herpesvirus, bornavirus, and Leukocytozoon were also flagged.

Why it matters: For veterinary professionals, the study adds case-based evidence that confiscated wildlife often arrives with complex, mixed health problems that can complicate triage, quarantine, diagnostics, and long-term placement. CITES guidance already emphasizes rescue centers as designated facilities for seized live animals and calls for quarantine and disease-risk management, and broader literature on illegal wildlife trade has shown that birds and reptiles are common trafficked taxa and can carry a wide range of pathogens, including zoonotic agents. Related pathology work also shows how unusual infectious causes can be missed without necropsy and targeted testing: in a recent Veterinary Pathology retrospective, schistosomes were found in the brains of 12 aquatic birds, with neuroschistosomiasis likely contributing to death in 5 cases, and PCR/sequencing identified Dendritobilharzia pulverulenta in several samples. The authors’ main takeaway in the Spanish confiscation study was practical: individualized treatment and management may be more appropriate than population-based protocols often used in other zoological settings.

What to watch: Watch for a full peer-reviewed paper with expanded methods, species-level breakdowns, and any recommendations that rescue centers and regulators could translate into intake, quarantine, and husbandry protocols. It would also be useful to see whether future reports capture less common but clinically important infectious findings through molecular diagnostics, as has been done in recent avian neuroschistosomiasis work.
