Viral skin virulence in rabbits.

Viral skin virulence in rabbits with intradermal inoculation. Rabbits were inoculated intradermally in dorsal skin with 102 to 105 PFU viral preparations from five TT clones, parental TT (752-1), and NYCBH. The average lesion diameter (mm) and putrescence incidence percentage are shown.家兔皮内接种后的病毒皮肤毒力测定实验。将5株TT克隆株、亲本TT株（752-1）以及NYCBH株的病毒制剂，以10²至10⁵ 蚀斑形成单位（plaque-forming unit, PFU）的剂量，于家兔背部皮肤实施皮内接种。实验结果以病灶平均直径（单位：毫米）及腐坏发生率进行呈现。
