FIG. 6.

Mouse body weights after infection with VEE TC-83 or SIN-83 viruses. Six-day-old NIH Swiss mice were inoculated s.c. with 2 × 10⁶ PFU of VEE TC-83 or SIN-83 viruses. Ten animals were used per virus, and six noninfected animals of the same age were included as a control group. The body weight of each animal was determined weekly. Weights of the VEEV TC-83-infected mice that died were excluded from the study. Error bars indicate standard deviations.
