Adobe Acrobat XI Pro was used to OCR the text and also for the merging and conversion to the final presentation PDF-format.Cytopathogenic activity by egg adapted strains of bluetongue virus for sheep kidney cells in culture, and the neutralization of this activity by homologous antiserum are described. The possible applications of this phenomenon to studies on various phases of bluetongue is discussed briefly. Reference is made to preliminary studies which indicate that the property of cytopathogenesis is not associated with virulent, unmodified, bluetongue virus.en© 1956 ARC - Onderstepoort and Faculty of Veterinary Science, University of Pretoria (original). © 2016 University of Pretoria.
