Myocardial pathology of domestic ruminants in southern Africa.

Myocardial pathology of ruminants in southern Africa, including lesions associated with toxic plants, other toxic agents, infectious agents and nutritional deficiency, is discussed with regard to recognition and to aetiological diagnosis. Findings are included which have not been published elsewhere. The importance and difficulties in recognition of myocardial lesions at an early stage are emphasized. Further research into the pathology of cardiac failure caused by toxic plants is clearly needed.
