Fig. 2From: Transcriptional analysis of bla NDM-1 and copy number alteration under carbapenem stressCopy number of bla NDM-1 within IncFIC plasmid. 0 μg/ml (control) = copy number of bla NDM-1 without any antibiotic pressure. 0.5, 1, 2 and 4 μg/ml = change in copy number of bla NDM-1 under 0.5, 1, 2 and 4 μg/ml exposure of imipenem (blue bar), meropenem (red bar) and ertapenem (green bar) pressure. The error bars represent the standard deviation of the three replicates of one sampleBack to article page
