Endogenous microbiome pathway activity patterns influence the colonisation efficiency of PDB
To investigate whether variations in the FMM data were associated with the highly variable and subject-specific relative abundance of PDB during the intervention periods, RDA analysis was performed using the FMM determined during the intervention periods and, as explanatory variable, the average relative abundance of PDB during their respective interventions (Fig. Small intestinal microbiota activity associates with the temporary colonisation by PDB. Taken together, our results highlight how the endogenous microbiota composition and its predominantly active energy metabolism could explain the individual-specific PDB colonisation efficiency, specifically identifying the
