The gut microbial composition is greatly influenced by the colonization of the recalcitrant pathogen\n                    <jats:italic>Helicobacter pylori<\/jats:italic>\n                    (\n                    <jats:italic>H. pylori<\/jats:italic>\n                    ) and the conventional antibiotic regimens that follow.\n                    <jats:italic>H. pylori<\/jats:italic>\n                    is considered to be the main microorganism in gastric carcinogenesis, and it appears to be required for the early stages of the process.

On the other hand, specific groups of gut microbes may produce beneficial byproducts such as short-chain fatty acids (acetate, butyrate, and propionate) that can modulate inflammation and tumorigenesis pathways.
