Colonization of Salmonella Choleraesuis rSC0012 in BALB/c mice at diferent time points. Mice were orally inoculated with 1.0 ± 0.3 × 109 CFU of the indicated strains. The numbers of bacteria loads in the Peyer’s patches (a), spleen (b) and liver (c) of mice at 3 d, 7 d, 14 d, 21 d and 28 d after inoculation were plotted. Bars represent the arithmetic mean ± standard deviations from two separate experiments each with 5 mice per group. *, P < 0.05; **, P < 0.01, for rSC0018 compared to rSC0012 or to rSC0011 with either pYA3493 or pS-SaoA; #, P < 0.05, ##, P < 0.01, for rSC0011 compared to rSC0012 or to rSC0011 with either pYA3493 or pS-SaoA; $$, P < 0.01, for C78-3 compared to rSC0011, rSC0012 and rSC0018 with either pYA3493 or pS-SaoA, as indicated. The data were collected from two independent experiments
