Figure 3

Association and invasion of monocytes U937 (a) or mononuclear cells directly extracted from human blood (b). The strains used include S. Typhi STH2370 WT (black), S. Typhi STH2370 ΔstgABCD::FRT (Δstg) (white), S. Typhi STH2370 ΔstgABCD::FRT/pSstgstg/pSstg) (fark grey), and S. Typhi STH2370 ΔstgABCD::FRT/pSU19 (Δstg/pSU19) (light grey) (a); and S. Typhimurium 14028s WT (black), S. Typhimurium 14028s WT/pSstg (white), and S. Typhimurium 14028s/pSU19 (dark grey) (b). The figure shows values expressed as the mean ± standard deviation of three full biological replicates, each time in technical triplicate. *p < 0.05 (Student’s-test) compared with the WT in the corresponding group.
