The gastric carcinoma microbiota is characterised by nitrosating bacteria. Functional classification of the predicted metagenome content of the microbiota of chronic gastritis and gastric carcinoma using (A) COG and (B) KO. The normalised relative frequency of nitrate reductase and nitrite reductase in patients with chronic gastritis and gastric carcinoma is shown. Significance was considered for adjusted P<0.05. COG, Clusters of Orthologous Groups; KO, Kyoto Encyclopedia of Genes and Genome (KEGG) orthology; NADH, nicotinamide adenine dinucleotide; NO, nitric oxide; TMAO, trimethylamine N-oxide.
