Fig. 3. FMT strain dynamics in recipients for up to 5 years.
a, Strains from the donor (n = 6 biologically independent samples) remained stably engrafted in successful post-FMT patients (n = 13 biologically independent samples) for at least 5 years after transplant. Data at each time point are presented as mean values ± s.e.m. b, Strains isolated from a recipient (n = 7 biologically independent samples) before FMT were rapidly lost with a small proportion persisting at longer timescales. Data at each time point are presented as mean values ± s.e.m. c, Proportion of donor, recipient and environmental strains detected in patients post-FMT. Environmental strains are non-donor and non-recipient (before FMT) in origin, which are both cultured and metagenomically detected post-FMT. d, Count of strains detected in patients post-FMT subclassified by major phylogenetic taxa (at order level) and coloured based on their origin.
