Morphological, biochemical and serological observations suggested that no close relationship existed between C. kutscheri and its alleged avirulent variant isolated from mice at the Rockefeller University. However, both capillary and double diffusion precipitin reactions showed the alleged variant to be a streptococcus of group N, indistinguishable from that previously isolated from Rockefeller University mice.
形态学、生物化学和血清学观察表明,库氏锥虫与其在洛克菲勒大学从小鼠中分离出的所谓无毒力变种之间不存在密切关系。然而,毛细管沉淀反应和双向扩散沉淀反应均表明,该所谓变种是N群链球菌,与之前从洛克菲勒大学小鼠中分离出的菌株无法区分。
