The discovery of Helicobacter pylori ( H. pylori ) changed the dogma of the stomach as a sterile organ. H . pylori is an obligate pathogen in the human stomach and recognized as a definite carcinogen. Extensive research on the interaction of this bacterium with the gastric mucosa has been performed over the past three decades. The development of new nucleotide sequencing techniques and new biocomputational tools has opened the field for studying the diversity and complexity of the microbiome in the gastrointestinal tract independently of cultural methods. These techniques allow to better characterize further gastric bacteria. However, the differentiation of alive resident and transient microbes requires an analysis beyond the pure detection of bacterial genomic material applying a combination with metabolomic analyses. Currently, the interaction of gastric microbiota with each other, with H . pylori and with the host is addressed by extensive research. This review gives a concise overview on current knowledge on this topic.
