(G-I) Brucella replication in BMMs treated with non-targeting siRNAs (siNT), or siRNAs against Rab6a/a' (siRab6a/a') (G), Rab8a (siRab8a) (H) or Arf6 (siArf6) (I) and infected with either wild type (2308), ΔbspF, or complemented ∆bspF (ΔbspF::bspF) bacteria, measured as number of bacteria per cell at 24 h pi. Data are means ± SD of n=3 independent experiments in which at least 100 cells were analyzed per experiment. Grey dots represent individual cells analyzed; black dots indicate means of individual experiments. Asterisks indicate statistically significant differences (P<0.05, one-way ANOVA followed by Dunnett's multiple comparisons test) between test and control conditions.
