Multiple environmental and genetic factors are involved in the development of gastric cancer. In the present study, we aimed to determine the microbial composition of gastric mucosa from the patients with chronic gastritis, intestinal metaplasia, and gastric cancer and to analyze any difference in the microbial composition among three groups using high throughput sequencing platform, 454 GS FLX Titanium.
