Onderstepoort Veterinary Institute
The ARC-Onderstepoort Veterinary Institute (ARC-OVI), has a long tradition of veterinary research since its founding in 1908 by Sir Arnold Theiler. It is nationally and internationally recognized as a veterinary centre of excellence. The ARC-OVI is a flagship institution of the Agricultural Research Council and plays an important role in maintaining the health of our national herd and wildlife. This collection (in an experimental phase) consists of the following sections:
General veterinary history collection
African animal trypanosomiasis (Nagana) collection
