Phylogenetic trees of fecal bifidobacterial isolates from FMT donors and their recipients. (A) Phylogenomic tree based on concatenated amino acid sequences of 49 single copy genes of ribosomal proteins of all the isolates and NCBI reference genomes. Note that the tree is topological and branch distance is therefore unindicative of phylogenetic distance. (B) Phylogenetic tree of B. longum isolates based on whole genome SNP calling. The colors in isolate codes indicate an isolate’s rep-PCR fingerprint group. The branch support values represent proportions among 1,000 bootstraps. DX and DY, FMT donors; PX1-4 and PX6-7, FMT recipients of DX; PY1 and PY5, FMT recipients of DY. F1, F2, F4, F5, and F7, 3 days, 2 weeks, 2, 4, and 12 months post-FMT, respectively; pv1-54, isolate codes; DX_pv5_PacBio and DX_pv32_PacBio, two DX isolate genomes that were sequenced by PacBio in addition to MiSeq; REF, reference strains from the NCBI reference genome database (Supplementary Table 5).
