title: Generalized amyloidosis in an Eastern Bongo (Tragelaphus eurycerus isaaci).
abstract: Amyloidosis has been described in a wide range of domestic and wild species and man. A 10-yr-old male Eastern (Mountain) Bongo (Tragelaphus eurycerus isaaci) was submitted for postmortem examination after a period of 24-hr malaise. Gross examination found evidence of biventricular cardiac hypertrophy, congestive heart failure, and focal pulmonary abscessation. Histologic changes in the heart were consistent with hypertrophic change. Amyloid deposits were found within the liver, kidney medulla, heart, adrenal cortex, and pituitary gland and were confirmed as reactive systemic amyloid (AA) by immunohistochemistry. The pulmonary abscessation was thought to be the stimulus for excessive serum amyloid associated protein production leading to the reactive systemic amyloidosis. Colloidal goiter was also identified as an incidental finding.
