Phagocytosis and replication of the <i>mgtC</i> mutant in the J774 macrophage cell line.

<p>(A) Phagocytosis of the <i>mgtC</i> mutant and complemented strains by J774 macrophages is normalized to 100% for the wild-type strain. Results are expressed as means+SD from four independent experiments. (B) Numeration of macrophages infected with <i>mcherry</i>-expressing bacteria, normalized to 100% for the wild-type strain. Results are expressed as means+SD from three independent experiments. (C) Replication of the <i>mgtC</i> mutant and complemented strains by J774 macrophages normalized to the wild-type strain. Results are expressed as means+SD from four independent experiments. (D) Kinetic of phagocytosis of the <i>mgtC</i> mutant and complemented strains by J774 macrophages normalized to 100% for the wild-type strain at 180 min. The <i>wbbl2</i> mutant strain is used as a positive control. Results are expressed as means ± SD (error bars) from three independent experiments. Asterisks indicate statistical significance (* <i>P</i><0.05; ** <i>P</i><0.01).
