FIG. 3.

Salp15 increases the bacterial burden and delays resolution of infection with the S. enterica serovar Typhimurium aroA mutant. Mice were infected with 10⁸ aroA-deficient bacteria harboring either the salp15 gene (Salp15) or the empty plasmid (eGFP). Bacterial burdens in the spleens of the infected animals were assessed over the course of infection by plating a section of the spleens in Luria-Bertani medium containing 50 μg of kanamycin/ml. The data represent numbers of CFU per milligram of tissue. The data at each time point represent the average of results for two mice.
