Suspected cardiac glycoside poisoning in elephants (Loxodonta africana).
Two young (< 2 years old) elephants (Loxodonta africana) died suddenly and simultaneously at Ongava Game Reserve bordering on the Etosha National Park, Namibia. Both elephants showed lung congestion, epi- and endocardial haemorrhages and hyperaemic areas in the mucosa of the stomach and small intestine. Histopathology of the myocardium showed multifocal degeneration and necrosis of muscle fibres accompanied by haemorrhages. Parts of the leaves of the alien plant Cryptostegia grandiflora (Asclepiadaceae) were found in the intestinal tracts of the elephants. These findings suggested that the elephants died from heart failure after ingesting this plant which contains cardiac glycosides.
