The environmental microbiome had minimal impact on gut microbiome analysis. a Two microbiomes were analysed from the intestinal tract, namely faecal and caecal content samples collected when tumours reached 50 mm3 and 350 mm3, respectively. b Quantification of bacterial load from different tissue and luminal contents from mice, with E. coli (1 × 102, 1 × 104, 1 × 106 CFUs) as controls (n = 1 mouse). c Comparison of the total amount of nucleic acid quantified by PicoGreen assay in all samples collected when the tumours reached 50 mm3 and 350 mm3. d Common bacterial taxa at the species level in 4 samples of PBS, as negative controls of DNA extraction by 16S rRNA sequencing
