RESUMO
Of 500 red-footed tortoises imported to southern Florida, approximately 200 died during a 2-month period. Clinical signs were nonspecific and included anorexia, listlessness, and watery diarrhea, with lingering death. Necropsy consistently revealed thickened duodenum, with necrotic mucosa and multifocal to diffuse areas of hepatic necrosis. Histologic evaluation of tissues demonstrated numerous amebae in intestinal and hepatic lesions.

Five Bolivian side-neck turtles had multifocal small, round to confluent, white skin lesions distributed over the head. Several gram-negative microorganisms were isolated from the lesions. Light microscopy revealed hyperkeratosis and hyperplasia of the epidermis. Ultrastructural evaluation demonstrated crystalline aggregates of virus particles within nuclei of cells in the stratum granulosum and free within the stratum corneum. On the basis of size, location, arrangement, and tissue affected, the particles resembled papillomaviruses.
