Fig. 3From: Immunogenicity and protective efficacy of a Salmonella Enteritidis sptP mutant as a live attenuated vaccine candidateBody weight (a) and bacterial colonization in mouse organs post immunization. Salmonella colonization and persistence in the liver (b), spleen (c), and mLN (d) of mice following oral immunization with 1 × 107 CFU or 1 × 108 CFU of C50336ΔsptP. Control mice received 100 μl of PBS and were negative for Salmonella in the liver, spleen, and mLN. The number of Salmonella was determined and represented as Log10 CFU/gBack to article page
