    Amebiasis caused significant mortality in imported red-footed tortoises. Necropsy revealed intestinal and liver damage, with amebae identified as the cause of death in these reptiles.

    Area of Science:

    • Veterinary Pathology
    • Herpetology
    • Parasitology

    Background:

    • Red-footed tortoises (Chelonoidis carbonarius) are popular exotic pets.
    • Imported reptiles can introduce novel pathogens and diseases to naive populations.
    • Disease outbreaks in captive wildlife pose significant challenges to animal health and conservation efforts.

    Purpose of the Study:

    • To investigate the cause of mortality in a group of imported red-footed tortoises.
    • To characterize the clinical, gross, and microscopic findings associated with the disease outbreak.
    • To identify the causative agent responsible for the observed pathology.

    Main Methods:

    • Clinical case review of affected tortoises.
    • Gross necropsy examination of deceased animals.

  • Histopathological evaluation of intestinal and hepatic tissues.
  • Microscopic identification of protozoal organisms within lesions.

    • Main Results:

    • Approximately 40% mortality (200/500) occurred within two months of importation.
    • Clinical signs included anorexia, listlessness, and watery diarrhea.
    • Consistent findings at necropsy were duodenal thickening with mucosal necrosis and multifocal hepatic necrosis.
    • Histology revealed numerous amebae within intestinal and hepatic lesions.

    Conclusions:

    • Amebiasis is identified as the cause of significant mortality in this group of imported red-footed tortoises.
    • The findings highlight the potential impact of parasitic infections on captive reptile populations.
    • Early diagnosis and treatment are crucial for managing amebiasis in tortoises.
