FIGURE 1: P. aeruginosa MgtC promotes an intramacrophage phase and limits biofilm formation.

Expression of P. aeruginosa mgtC gene is induced inside macrophages and in magnesium-deprived medium. P. aeruginosa MgtC is involved in resistance to macrophage, a feature shared with MgtC proteins from intracellular pathogens as S. Typhimurium. Under magnesium deprivation, MgtC promotes planktonic growth but limits biofilm formation and EPS production.
