Helicobacter species ribosomal DNA in the pancreas, stomach and duodenum of pancreatic cancer patients

Figure 1 Agarose gel electrophoresis (A), DGGE (B), and the outcome of a public database comparison of Helicobacter 16S ribosomal DNA PCR-product sequences (C). From 7 pancreatic cancer patients (P), amplicons from the duodenum (D), fundus ventriculi (Fv), and antrum ventriculi (Av) were compared to amplicons from normal (Pn), atrophic (Pa) and pancreatic tumor (Pt) tissues. Migration markers (M) were (from top to bottom) amplified from DNA of H. bilis (1), H. pullorum (2), H pylori (3), H. sp. flexispira (4) and H. hepaticus (5).
