Comparison of gut microbiomes between axial spondyloarthritis (axSpA) patients and healthy controls (HCs). Feces were obtained from axSpA patients (N = 33) and HCs (N = 20), and 16s rRNA was analyzed using next generation sequencing. (A) α-diversity measured by observed OTUs and Chao1 score and (B) β-diversity using PCoA based on Bray-Curtis dissimilarity between axSpA patients (N = 33) and HCs (N = 20). Pearson’s correlation (r) and the corresponding P values are presented. Relative abundance of gut microbes in axSpA patients and HCs according to genus (C, D), and species levels (E, F). Species-level gut microbes that were significantly different between groups are presented. OTUs, operational taxonomic units; PCoA, principal coordinate analysis.
