BRD2 and neoplasm: At the genus level, similarly to the NAT group, Acetobacter (V1V2 p = 0.0003; V4/V5 p = 0.006; V5V7 p = 0.004; V7V9 p = 0.003) and Liquorilactobacillus (V1V2 p = 0.007; V4/V5 p = 0.001; V5V7 p = 0.007; V7V9 p = 0.03) were absent or of low abundance in most Tumor samples, whereas Ralstonia was highly abundant when compared with Normal (V1V2 p = 0.04; V4/V5 p = 0.04; V5V7 p = 0.04; V7V9 p = 0.03) (Fig. 2B and Additional file 2: Fig S6).
