Echinococcus multilocularis in two lowland gorillas (Gorilla g. gorilla).

An unusual presentation of alveolar echinococcosis was observed in two lowland gorillas (Gorilla g. gorilla). Clinical signs included progressive abdominal enlargement, apathy and anorexia. Macroscopical changes consisted of severe peritonitis and foci of hepatic necrosis with large cavities replacing most of the normal tissue. Additionally, a few structures resembling hydatid cysts were present. Histologically, some necrotic areas contained fragments of a laminated wall characteristic of echinococcal metacestodes. Only a few areas showed the multiloculated architecture typical of Echinococcus multilocularis. Serum antibodies against E. multilocularis antigen were detected in both animals, and granulomatous and necrotizing hepatitis with severe peritonitis due to E. multilocularis was diagnosed. The pathological changes in alveolar echinococcosis in gorillas appear to resemble more closely those found in human beings than those in other non-human primates.
