Control animals were given uninfected Vero cell lysate. Survival (A) and clinical scores (B) were monitored daily after inoculation. Clinical scores were defined as following: 0,healthy; 1,ruffled hair, hunchbacked or reduced mobility; 2,limb weakness; 3,paralysis in 1 limb; 4,paralysis in both limbs; 5,death. Each group contained seven or eight gerbils. One representative of two independent experiments was shown.
