Influence of mouse gut microbiome on human fecal species. a Relative abundances of the total human fecal microbes that colonized different mouse gut environments. b Species richness of human fecal microbes in the FMT-established microbial communities. p-values of Wilcoxon rank sum test were shown. c Human fecal species enriched in nonABT versus ABT mice. Linear Discriminant Analysis score were shown for taxa showing significant enrichment (p < 0.05 and |LDA| > 2) when all samples were treated as independent. Additionally, the significance of enrichment were also shown with different sample pooling strategies: “average across time points” – samples representing time points of a same mouse were combined, “average across time points and co-caged mice”—samples representing time points of all mice in a same cage were combined. Names of species that were consistently enriched (p < 0.1) in nonABT or ABT mice for both mouse genotypes were highlighted in orange. LDA linear discriminant analysis
