Antibiotics resistance in the foodborne pathogen Listeria monocytogenes emerging in recent years increases a public health concern. In order to investigate the genetic mechanisms of antimicrobial response in L. monocytogenes, the ability of the stress responsive alternative Sigma factor mutant EGDeΔsigB tolerant to six different antibiotics was analyzed by minimal inhibitory concentration (MIC) and the growth assays. Our results showed that the MICs of EGDeΔsigB were significant lower than that of wild type EGDe in penicillin G, erythromycin, and gentamicin media. The growth of EGDeΔsigB was inhibited strongly in the four times MIC of the antibiotics tetracyclin HC1, Rifampicin and Ampicillin. All these data indicate that σ^B plays a very important role in L. monocytogenes antibiotics resistance.
