Fig. 2From: Toxigenic and non-toxigenic patterns I, II and III and biofilm-forming ability in Bacteroides fragilis strains isolated from patients diagnosed with colorectal cancerComparison of bft gene expression in Bacteroides fragilis strains under planktonic and biofilm conditions. The black bars represent the average fold-change ± SD (1.64 ± 0.96) of bft gene expression under planktonic condition and gray bars represent the average fold-change ± SD (0.50 ± 0.38) of bft gene expression under biofilm condition. *Indicates statistical significance (P = 0.001)Back to article page
