Fig. 4From: luxS contributes to intramacrophage survival of Streptococcus agalactiae by positively affecting the expression of fruRKI operonThe promoter activity of fruRKI in S. agalactiae strains grown in rich medium or chemically defined medium (CDM). A The fruRKI promoter activity in the WT, ΔluxS and CΔluxS strains cultivated in THB (rich medium). B The fruRKI promoter activity in the WT, ΔluxS and CΔluxS strains cultivated in CDM supplemented 1% fructose. Data are presented as the mean ± SD of three independent experiments. ***P < 0.001.Back to article page
