Loss of mazEF expression decreases survival of MRSA during chronic PJI in vivo. Mice given PJI were euthanized at 1-, 3-, 7-, and 14-day post infection (n = 3 per group). Infected implants were quantified over time (A). Acute (days 1 and 3) and chronic (days 7 and 14) displayed mazF::tn increased acute bacterial burden (**p < 0.01) (B) and decreased chronic bacterial burden (C) compared to WT. Proximal bone tissue of infected joint also displayed this same trend as implants (*p < 0.05) (D–F).
