Fig. 6

Attenuated S. Typhimurium ΔznuABC vaccine and inactivated S. Choleraesuis vaccine induce antibody production. Symbols and bars represent mean and standard deviation of s/p ratio in 3 groups, respectively. The pattern of humoral immunity is similar between group A (vaccinated with Attenuated S. Typhimurium ΔznuABC) and in group B (vaccinated with killed S. Choleraesuis). The X-axis is divided into two segments to differentiate between antibody response after vaccination (DAV) and challenge (DAC). Differences are statistically significant between vaccinated piglets with attenuated strain and unvaccinated piglets from day 18 after vaccination. On the contrary, differences are statistically different between vaccinated piglets with inactivated strain and unvaccinated piglets only at day 35 and 47 after vaccination. Gray star indicates significant difference between groups B and C, while black star indicates significant difference between group A and C
