WebBiotypes (cytopathic vs. noncytopathic) are defined on the basis of cytopathic effects in cultured epithelial cells. However, virulence phenotype in vivo correlates with the noncytopathic rather than the cytopathic biotype. The authentic form of BDV is predominantly an ovine pathogen, although pigs are also affected.
