Figure 4From: The effect of environmental conditions on expression of Bacteroides fragilis and Bacteroides thetaiotaomicron C10 protease genesResponse of B. thetaiotaomicron and B. fragilis C10 protease genes to environmental stimuli. The change in expression of the four btp genes in B. thetaiotamicron (a) and the four bfp genes in B. fragilis (b) was examined in response to atmospheric oxygen (light grey bar), bile (dark grey) and blood (white bar). In both plots, values between +/− 1 fold change indicate no significant alteration of gene expression compared to the control.Back to article page
