Figure 6. In mixed-infections of macrophages, FeoB limits S. Typhimurium replication.
RAW264.7 Nramp1+ cells were resting (A) or treated with IFNγ and LPS (B) or IL-4 (C) and were inoculated with a 1:1 mixture of WT and ΔfeoB strains. Mean and SD of representative experiments are shown. p-values were determined as described in the methods. p < 0.05 (*) vs. the null hypothesis, n ≥ 3 experiments.
