Identification of a new group of bovine viral diarrhea virus strains associated with severe outbreaks and high mortalities.

abstract：:Cauliflower mosaic virus (CaMV) strains CM1841 and W260 produced markedly different symptoms when inoculated onto turnips (Brassica campestris L. 'Just Right'). The CM1841 strain induced a mild degree of stunting of infected plants while strain W260 caused moderate to severe stunting. Although CM1841 was significantly...
