Detection of Mutations in the soxRS , marRAB , acrR and ramR regulatory loci ( as it is already known , RamR exert a positive effect on AcrAB/TolC expression , whereas AcrR is the local repressor ) was performed using the corresponding primers .
Detection of Mutations in the soxRS , marRAB , acrR and ramR regulatory loci ( as it is already known , MarA exert a positive effect on AcrAB/TolC expression , whereas AcrR is the local repressor ) was performed using the corresponding primers .
Detection of Mutations in the soxRS , marRAB , acrR and ramR regulatory loci ( as it is already known , the transcriptional regulators SoxS exert a positive effect on AcrAB/TolC expression , whereas AcrR is the local repressor ) was performed using the corresponding primers .
