  • a Salmonella strains are as described in the legend to Fig. 2.

  • b Expression levels of PmlrA and PrpoS::lux fusions generated from ATCC 14028 were measured in each strain background. Values represent the means and standard deviations of maximum luminescence from at least three independent experiments.
