Gut microbiota may have an impact on obesity. To date, the majority of studies in obese patients reported microbiota composition in stool samples.The aim of this study was to investigate the duodenal mucosa dysbiosis in adult obese individuals from Campania, a region with a very high percentage of obese people in Italy, to highlight microbial taxa likely associated to obesity.Duodenum biopsies were taken during upper gastrointestinal endoscopy in 19 obese (OB) and 16 lean control subjects (CO) and microbiome studied by 16S rRNA gene sequencing.
