Mean group morbidity scores ((a), (c), and (e)) and mean weight changes ((b), (d), and (f)) in BALB/c, CBA/Ca, and C57BL/6 mice following i.p. inoculation with 1 × 10⁶, 5 × 10⁶, or 25 × 10⁶  NC-Liv tachyzoites. Mice were scored for clinical symptoms including hunched back, ruffled hair coat, impaired movement, and spinning when picked up by the tail, resulting in a maximum clinical score per mouse of 4. Figures 1(a), 1(c), and 1(e) show the average clinical score per mice per group. ∗indicate the death of a mouse; error bars ± SD; n = 5.
