Infectivity of Toxoplasma gondii bradyzoites was compared in outbred female Sprague Dawley rats and outbred Swiss Webster mice. Rats inoculated subcutaneously with 1-10 bradyzoites of the 2 strains of T. gondii (VEG and GT-1) developed persistent infection, whereas an infective dose by the oral route was 10-1,000 bradyzoites. The infectivity of bradyzoites of the VEG and the GT-1 strains of T. gondii in rats by the subcutaneous route was comparable to that in mice.
在远交系雌性斯普拉格-道利大鼠和远交系瑞士韦伯斯特小鼠中比较了刚地弓形虫缓殖子的感染性。皮下接种1 - 10个刚地弓形虫2个菌株（VEG和GT - 1）缓殖子的大鼠发生了持续性感染，而经口途径的感染剂量为10 - 1000个缓殖子。刚地弓形虫VEG株和GT - 1株缓殖子经皮下途径在大鼠中的感染性与在小鼠中的相当。
