Given this we collected gastric antrum and gastric body biopsies from healthy controls (HC.A and HC.B group) and gastric antrum, gastric body and polyp biopsies from patients with multiple gastric polyps (GP.A, GP.B and GP.P group) for 16S rDNA sequencing. The results showed that the diversity of the gastric flora in the GP group was significantly lower than that of the HC group. The gastric flora composition of the GP group was significantly different from the HC group. However, flora diversity and compositions in different parts of the stomach (gastric antrum, gastric body or polyp tissue) were not significantly different. <jats:italic>H. pylori<\/jats:italic> abundance could influence the composition of gastric microbiota. Meanwhile, patients with fundic gland polyps (FGPs) and those with hyperplastic polyps (HPs) had considerably similar gastric bacterial compositions. We constructed a microbial dysbiosis index (MDI) based on the gastric microbiota at the genus level as a predictive model, and it was able to distinguish between individuals in the GP and HC groups. These findings showed that intragastric flora dysbiosis may be closely related to the occurrence and development of gastric polyps.<\/jats:p>","DOI":"10.1038\/s41598-018-31738-2","type":"journal-article","created":{"date-parts":[[2018,9,10]],"date-time":"2018-09-10T10:23:38Z","timestamp":1536575018000},"update-policy":"http:\/\/dx.doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["The gastric mucosal-associated microbiome in patients with gastric polyposis"],"prefix":"10.1038","volume":"8","author":[{"given":"Rongrong","family":"Ren","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zikai","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Huaibo","family":"Sun","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xuefeng","family":"Gao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gang","family":"Sun","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lihua","family":"Peng","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bin","family":"Yan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yunsheng","family":"Yang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2018,9,14]]},"reference":[{"key":"31738_CR1","doi-asserted-by":"publisher","first-page":"1524","DOI":"10.1038\/ajg.2009.139","volume":"104","author":"SW Carmack","year":"2009","unstructured":"Carmack, S.
