Fig. 1.
Relative quantities of gene targets of the original bacterial community in fecal samples from healthy controls (white), ulcerative colitis patients in remission (gray), and ulcerative colitis patients in relapse (black). Target genes encoded 16S rRNA from Lactobacillus spp., Bifidobacterium spp., Firmicutes, Bacteroidetes, Clostridium coccoides group, Clostridium leptum subgroup, Faecalibacterium prausnitzii, and Desulfovibrio spp. The relative quantities (RQ) were calculated as RQ = EΔCT, where E represents the primer efficiency and ΔCT was the CT value of the bacterial target normalized against the CT value of the total bacterial population in the sample. Total bacteria were set to 100% (indicated by dotted line). Error bars represent averages ± standard errors of the means of relative quantities in target species in each of the six samples in each group. Asterisks indicate a significant difference among groups (P < 0.05).
