Figure 3From: Systematic analysis of the regulation of type three secreted effectors in Salmonella enterica serovar TyphimuriumEffect of chromosomal regulators on the expression of slrP. β-galactosidase assays were performed on log-phase cultures (using Beta-glo reagent). The results represent a mean of at least three independent assays. WT, wild type; invF, invF mutant; sicA, sicA mutant; sprB, sprB mutant, MM + pinvF-sicA, multi-mutant containing the plasmid encoding invF and sicA; MM + psprB, multi-mutant containing the plasmid encoding sprB.Back to article page
