Relative abundance of bacteria within gastric fluid, mucosal brushing, and fundal, corpus, and antral biopsies at (a) phylum and (b) operational taxonomic unit (OTU) levels. Fecal bacteria isolated from the patient and three age-similar healthy controls depicted at (c) phylum and (d) genus (when possible) or family levels. Patient’s microbiota represent single samples; controls represent average abundances from up to 23 fecal samples per healthy child obtained on separate days over one month as previously reported [Schloss et al. 2014].
