GLUL and metastatic neoplasm: A higher detection rate of DNA fragments coding for 16S rRNA, β-galactosidase of E. coli, glutamine synthase of B. fragilis, and 5.8S rRNA was detected in patients with metastatic disease compared to adjuvant patients (88.4% vs. 42.8%, p < 0.001; 31.7% vs. 21.2%, p = 0.017; 82.0% vs. 31.2%, p < 0.001; 81.0% vs. 37.0%, p < 0.001, respectively) (Table 2 and Data S1).
