The population of wild swine vesicular disease virus (SVDV) strains was found non-homogeneous as manifested by varying plaque size and different pathogenicity of the clones obtained. The clones derived from large plaques (5-9 mm)--dominating among wild strains--were more virulent for newborn mice than those obtained from smaller plaques (1-2 mm). To evaluate the pathogenicity of wild SVDV strains the dose index was calculated; the clones were compared by dose index and theoretical pathogenicity index, respectively.
野生猪水泡病病毒（SVDV）毒株群体表现出非均一性，这体现在所获得克隆的蚀斑大小各异以及致病性不同。从大蚀斑（5 - 9毫米）——在野生毒株中占主导地位——衍生出的克隆对新生小鼠的毒性比从小蚀斑（1 - 2毫米）获得的克隆更强。为评估野生SVDV毒株的致病性，计算了剂量指数；分别通过剂量指数和理论致病性指数对克隆进行比较。
