Growth of L. monocytogenes strains in BMM. A total of 2 × 106 wt (A) or LysM− (B) BMM were infected with wt, Pgd−, or Pgd− Oat− L. monocytogenes at an MOI of 0.1. A total of 2 × 106 wt (C) or LysM− (D) BMM were infected with LLO− L. monocytogenes strains at an MOI of 1. BMM were lysed, and bacterial CFU were quantified. Error bars represent standard deviations of the means of technical triplicates, and data are representative of more than 3 independent experiments with similar results. Student's t test was used to analyze statistical significance compared to wt L. monocytogenes infection at each time point. *, P < 0.05; **, P < 0.01; ***, P < 0.001; ****, P < 0.0001.
