Presence and quantity of F. nucleatum and B. fragilis in colorectal tissue. qPCR determination of presence and quantity of bacterial DNA in 99 colorectal tumor tissue, 76 paired normal tissue, 96 adenomas and 104 diverticula. a Prevalence of F. nucleatum and B. fragilis in colorectal tissue. Positivity was determined as bacterial species with a DNA quantity above the LOD of the primers. b Prevalence of F. nucleatum and B. fragilis in different stages of CRC. No statistical significant differences were observed. c Difference in quantity of F. nucleatum and B. fragilis DNA in colorectal tumor tissue compared to paired normal tissue, adenomas and diverticula as well as in adenomas compared to diverticula. Brackets denote standard deviation. * P < 0.05, ** P < 0.001
