摘要
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.
