• Description: Introduction: These days gastroesophageal reflux disease (GERD) represents one of the significant health problems of western countries as a result of several lifestyle factors. Prolonged GERD leads to esophageal inflammation and significantly increases the risk of Barrett’s esophagus (BE) and the subsequent development of esophageal adenocarcinoma (EAC). There is an association between the esophageal microbiome and several esophageal diseases. However, it remains unclear whether the change in microflora leads to esophageal disease, or if this is a side effect of the highly acidic environment created by GERD. Our pilot study aimed to describe oral bacterial biota in patients with GERD and healthy controls from different parts of the esophagus, stomach and duodenum. Detailed microbiome analysis could contribute to early diagnosis and to the application of effective treatment in patients with GERD.
