Transfer of donor microbes to the patient, estimated at the species level. A The Bray-Curtis distance between the patient and the donor or the independent (not-used) donor over time. B The proportion of species common to the patient and the donor or independent donor over time. C Contributions to the patient post-FMT gut microbiota. Possible sources were divided into four categories, namely donor-specific (species from the donor and not shared with the patient pre-FMT), shared (species common to donor and the patient pre-FMT), recipient-specific (species from the patient pre-FMT and not shared with the donor), and newly detected (species not included in the above categories, possibly from the environment or below the detection limit). Line types indicate the measurement was performed with the donor (solid) or the independent donor (dashed). Fecal samples were collected from the donor and an independent (not-used) donor as well as from the patient during active CDI before the fecal microbiota transplantation (P-pre-FMT) and at 1 week (P1w), 8 weeks (P8w), 15 weeks (P15w), 22 weeks (P22w), 26 weeks (P26w, at term), and 50 weeks (P50w, 6 months after giving birth) after the FMT
