Donors and recipients in recombination events of core and shared accessory genes inferred by fastGEAR. For each of the three dominant STs (ST5, ST8, ST30), we subdivided the genomes into whether they came from a human host or animal host. We grouped all low-frequency STs into the Other STs category, which were further subdivided into whether they were human-derived (dark gray outer ring) or animal-derived (light gray outer ring). The length of the outer block is proportional to the number of genomes in which recombination was detected. Each line in the center connects a pair of donor and recipient genomes. For each line, the recipient genome is indicated by the end of the line ending nearer the outside of the plot and the potential donor cluster is indicated by the end of the line nearer the center of the plot. The color of the connecting line is based on the color of the recipient genome. The width of the lines in the center is proportional to the number of recombination events between a pair of genomes from the respective groups. The list of all recombination events is presented in Supplementary Table S5
