Transcription of MdrM transporter homologs is induced during L. monocytogenes intracellular growth. Transcription analysis of mdrM-like transporter genes during L. monocytogenes 10403S intracellular growth in BMD macrophages at 6 h p.i. in comparison to their levels during exponential growth in BHI medium using RT-qPCR analysis. Transcription levels are represented as relative quantity (RQ) compared to the transcription levels during growth in BHI. If the transcript levels are equal under both conditions, RQ = 1. Transcription levels were normalized to the levels of 16S rRNA as a reference gene. The data are representative of 3 independent biological repeats (n = 3). Error bars represent 95% confidence intervals (as described in Materials and Methods).
