Kinetics of intratracheal infection with B. suis. BALB/c mice were infected with 5 × 10⁴ CFU/mice of B. suis wt. At 1, 7 and 30 days post-infection mice were euthanized, and the lungs, spleens, and livers were removed. Dilutions of organs homogenates were plated and CFU were counted. Values are means ± SD of duplicate measurements from three independent experiments. Asterisks indicate significant differences between 1 and 7 days and up arrowheads and crosses significant differences between 7 and 30 days. ****p < 0.0001; ^∧∧∧p < 0.001; ⁺⁺⁺⁺p < 0.0001.
