Figure 2.
Survival curves of mice injected with 5 × 107 CFU of live S. parasuis strain BS26, S. parasuis strain BS27, S. suis strain P1/7, and PBS only as control group. Overall survival rates of the two experiments for each group (calculated via the Kaplan-Meier method) at 2 h, 4 h, 6 h, 8 h, 10 h, 12 h, 18 h, 24 h, 36 h, 48 h, and 72 h post-infection were present in survival curve. The survival rates of different groups were compared using Log-rank test. *, significantly different (p < 0.05) compared to S. parasuis strains-infected group and control group. §, significantly different (p < 0.05) between S. parasuis strains-infected group and control group.
