Fusobacterium nucleatum colonization is associated with decreased survival of helicobacter pylori-positive gastric cancer patients

Figure 3 Identification of Fusobacterium nucleatum in the resected gastric cancer tissues. A: Fusobacterium nucleatum (F. nucleatum) was detected by amplification of the conserved NusG gene sequence using nested polymerase chain reaction method. The end point product was analyzed using 6% nondenaturing polyacrylamide gel electrophoresis; B: The relative risk of F. nucleatum colonization was analyzed against the sex, age, status of Helicobacter pylori colonization, and cancer stage. Data analysis is shown as Forest plot.
