Figure 2. Intracellular proliferation of S. Typhimurium wild type, ΔmsrA, ΔmsrB, ΔmsrAΔmsrB in RAW 264.7 cells.

Figure 2

A. S. Typhimurium wild type, ΔmsrA, ΔmsrB, ΔmsrAΔmsrB, ΔmsrA + pBAD30::msrA and ΔmsrAΔmsrB + pBAD30::msrA were tested in IFN-γ-activated RAW 264.7 cells. B. S. Typhimurium wild type, ΔmsrA, ΔmsrB, and ΔmsrAΔmsrB, were tested in non-stimulated RAW 264.7 cells. Intracellular proliferation was determined in a gentamicin protection assay. Number of bacteria 16 h post infection was divided by the number of bacteria 2 h post infection. Results shown are the means ± standard error of the mean for three independent experiments, each in triplicate. P-values <0.05 were considered to be significant as indicated by asterisks. ns: not significant.
