Analysis of gene expression changes in S. aureus by qPCR in response to L. reuteri RC-14 supernatant. Quantitative PCR analysis of (A) S. aureus MN8, (B) S. aureus MN8 isogenic Δagr mutant, and (C) S. aureus strains Newman, Mu50, and SK46. RNA was isolated from S. aureus strains grown in BHI, and in BHI supplemented with fourfold-concentrated L. reuteri RC-14 supernatant (BHI+SUP) to postexponential growth phase (8 h for MN8 and Δagr mutant, 6 h for others). Values (mean ± SEM) were obtained from at least three independent samples. ***P < 0.001, **P < 0.01, *P < 0.05. (D) Growth curves of S. aureus Newman, Mu50 and SK46 cultivated in BHI and in L. reuteri RC-14 supernatant (BHI+SUP).
