Fig. 4From: Horizontal gene transfer after faecal microbiota transplantation in adolescents with obesityBacteroidetes are overrepresented contributors to HGT. HGT events between donor-engrafted species and recipient species in a females and c males, clustered by phylum. Tiles are coloured by the number of HGT events between each donor-recipient species pairing. b Relative abundances of bacterial phyla across donor genes on high-quality MAGs (‘background’), donor bacterial phyla engrafted in FMT recipient gut microbiomes at week 6 (‘engrafted’), and those engrafted strains that contributed to HGT (‘engrafted with HGT’). Phylum distributions for engrafted and engrafted with HGT bacteria were compared (chi-squared test). ***p < 0.001.
