Mortality and viral loads of A129 mice subcutaneously inoculated with the JaOArS982 strain of JEV. Mortality (A) and survival (B) rates of mice inoculated with 100, 102, 104 or 106 pfu of JEV (n=10 per group). p: Log-lank test. Infectious virus titers in the spleens (C) and brains (D) of mice inoculated with 100, 102, 104 or 106 pfu of the JaOArS982 strain of JEV at 24, 48 and 72 hours pi (n=3 per group). Error bars represent the standard errors. P values were calculated by ANOVA at each time point.
