Fig. 2From: luxS contributes to intramacrophage survival of Streptococcus agalactiae by positively affecting the expression of fruRKI operonInfluence of luxS deficiency on carbon source availability of S. agalactiae strains. All strains were cultivated in a chemically-defined medium (CDM) supplemented fructose (A, B) or glucose (C, D) at a range of concentrations from 0.1% to 1% (w/v) as the sole carbon source, separately. Data are presented as the mean ± SD for three independent experiments. *P < 0.05, **P < 0.01, or ***P < 0.001, indicates a significant difference between the indicated strain and the WT strain.Back to article page
