(a). Electrophoresis of nested PCR products from gastric tissue and gastric fluid samples of 5 H. pylori-infected gerbils. 1–5 are the nested PCR products of gastric tissue, 6-10 are the nested PCR products of gastric fluid, respectively. (b) Gram staining of bacteria cultured from H. pylori-infected gerbils’ gastric mucosa, ×1000. (c–e) Oxidase, catalase, and urease reactions of bacteria cultured from H. pylori-infected gerbils’ gastric mucosa. 1–5 is the number of gerbils. 6 is the negative control. (c) Oxidase reaction. (d) Catalase reaction. (e) Urease reaction.
