Minor effects of enteral broad-spectrum antibiotics and fecal microbiota transplantation on gut microbiota composition. (a). Dissimilarity plots based on 16S rRNA gene amplicon sequencing data, visualizing differences in beta diversity of the colonic microbiota after AB (upper) and FMT (lower) treatment using Jaccard (left) and Unweighted UniFrac distances (right). (b). Shannon and Pielou’s evenness indices as measures of alpha diversity (data not sharing the same superscript letter are significantly different at p < .05). (c). Relative colonic bacterial abundance presented as stacked bar graphs summarized at order level of taxonomic classification. n = 13–16 per group for all analyses
