About this study

The primary objective of the study aims to compare the biodiversity of intestinal microbiota between spondylarthritis (SPA) or rheumatoid arthritis (RA) patients and healthy volunteers, by microbiota DNA sequencing in order to further and respond the prior results, which suggested that there is a specific dysbiosis for each of the 2 diseases. A comparative analysis will allow to identify the biomarkers of the specific bacteria.
