FIG. 3.

Competitive infections in mice. Mice were infected with a mixed inoculum of wild-type Salmonella serovar Typhimurium (wt) and either an hha mutant (left) or an hha ydgT double mutant (right). The CI for the hha strain and ydgT hha strain were determined for the spleen and liver at 72 h postinfection. Each data point represents one animal, and horizontal bars indicate geometric means. CI for hha/wt, P = 0.021 (spleen) and P = 0.001 (liver); CI for ydgT hha/wt, P < 0.0001 for spleen and liver.
