Relative gene expression (average S.D.) of fimA and hilA of Salmonella Typhimurium strain 112910a grown in LB-broth with subMIC
concentrations of different fatty acids relative to Salmonella Typhimurium strain 112910a grown in unsupplemented LB-broth at 37 8C for
20 h, using hilA-luxCDABE or fimA-luxCDABE transcriptional fusions. One or two asterisks refer to significantly lower or, respectively, higher
gene expression relative to that of the Salmonella Typhimurium strain 112910a grown in unsupplemented LB-broth ( p 0.05).
