    Summary

    A bacterial infection caused endocarditis and thromboembolic lesions in a bald eagle (Haliaeetus leucocephalus). This highlights the impact of bacterial diseases on avian wildlife health.

    Area of Science:

    • Veterinary Pathology
    • Wildlife Disease Ecology
    • Avian Pathology

    Background:

    • Bald eagles (Haliaeetus leucocephalus) are apex predators in North American ecosystems.
    • Understanding disease prevalence in bald eagle populations is crucial for conservation efforts.
    • Environmental factors can influence disease susceptibility in wildlife.

    Observation:

    • An adult male bald eagle was found deceased near its nest in California.
    • Gross examination revealed a thickened atrioventricular valve and a discolored, mottled liver.
    • These macroscopic findings suggested significant internal pathology.

    Findings:

    • Microscopic analysis confirmed bacterial vegetative valvular endocarditis.
    • Disseminated bacterial thromboembolic lesions were identified throughout the affected organs.
    • The results indicate a systemic bacterial infection.

    Implications:

    • Bacterial endocarditis and thromboembolism can be fatal in bald eagles.
    • This case underscores the importance of monitoring bacterial pathogens in wildlife.
    • Further research may elucidate transmission routes and environmental links to such infections.
