Bacterial load in liver and spleen of Salmonella-infected mice. Bacterial load [log₁₀ colony-forming units (CFU)/organ] in (a) liver and (b) spleen of nessy and C57BL/6 mice killed at certain times after infection with Salmonella enterica serovar Dublin SL5631 in three separate experiments. Mice in experiment 1 received approximately 1·2 × 10⁶ CFU and were killed at 2, 7 or 22 days postinfection (p.i.). Mice in experiment 2 received approximately 3·4 × 10⁶ CFU and were killed at 2, 7, 36/37 or 56/57 days p.i. In experiment 3, mice received approximately 1·2 × 10⁶ CFU and were killed at 22 days p.i. There is a significant difference between nessy and C57BL/6 bacterial loads from the spleen in experiment 3 (P < 0·05). Filled shapes represent nessy mice, open shapes represent C57BL/6 mice. Diamonds, experiment 1; squares, experiment 2; circles, experiment 3. Error bars represent standard deviation.
