Fig. 6: Influence of galactose catabolism on gene expression and capsule.
From: Environmental and genetic regulation of Streptococcus pneumoniae galactose catabolic pathways
Expression of selected genes (A) and quantification of glucuronic acid in galactose catabolic pathway mutants relative to WT. Values above and below (for downregulation) the dotted lines represent the significant levels of expression (B). Gene expression and glucuronic acid levels were quantified in pneumococci obtained 4 h after intranasal infection through lung lavage. Each column in (A) and (B) represents the mean of three experiments. For each experiment lung lavage from two mice were used. The mean recovered CFU for different strains was similar: D39: 1.81X107, ΔgalK: 1.9X107, ΔlacD: 1.7X107, and ΔgalKΔlacD: 1.76X107. Vertical lines show standard deviation.
