Fig. 2

BF638R1245 (recA); BF638R1246/7 (bcp); and BF638R1248 (sdh). White arrows indicate the promoters for each gene and the transcription direction. Putative promoters are shown in italics. (B) Relative fold increase in transcription of the three genes in the recA operon of B. fragilis. Transcription of BF638R1245; BF638R1246/7 and BF638R1248 was evaluated over time either being untreated (dark grey), after the addition of 1 μg/ml of metronidazole for 30 min (light grey) or 60 min (black), or after exposure to 100 μM H2O2 for 15 min (horizontal bars) or 30 min (white). Error bars represent the standard error of the mean.
