The effect of FMT on the jejunal microbiome composition and diversity of weanling piglets. A Stacked bar graph illustrating the actual abundance of jejunal gut microbiota at the genus level in control and FMT groups. B Heat tree depicting the hierarchical taxonomical distribution and relative abundance of significantly different microbial genera in control and FMT groups. The colors on the heat tree represent the median ratio of the log2-transformed abundance levels between the FMT and Control groups, with positive values (shades of red) indicating higher abundance in the FMT group and negative values (shades of blue) indicating higher abundance in the Control group. C Phylogenetic tree abundance map of microbial communities depicting comparative genetic diversity and the population density of the microbial genera in control and FMT groups. The blue square indicates selected genera that are significantly lacking in control weanling pigs but abundant in piglets that received FMT. The numbers surrounding the tree represent bootstrap values, indicating the confidence level of the branches. D Boxplot illustrating the Shannon index of alpha diversity within jejunal microbial communities of control and FMT groups; E Principal component analysis (PCoA) scatter plot demonstrating beta diversity among the jejunal microbiota of control and FMT groups
