ENGLISH ABSTRACT: The international demand for ostriches and their products has increased dramatically in the past years. This in turn has lead to an increase in the importance of infectious ostrich diseases. Due to the fact that South Africa is currently the largest producer of ostrich products in the world, the effects that infectious ostrich diseases can have on the local industry, are particularly relevant Newcastle disease (ND) can cause significant economic losses to the ostrich industry. Countries such as those in the European community importing ostriches or ostrich products, demand that they be certified virus free.
