Relationship of core genome SNP groups to spatial and temporal distance. a Clonality results for A. baumannii. Squares represent A. baumannii collected from surfaces. Colors represent clonal subgroup membership. Each colored set is a clonal subgroup with fewer than five SNPs different between all members of the group. Unfilled squares did not have fewer than five SNPs different with any other isolates. Lineage from BAP (identified in Fig. 3 by branch color) is indicated in the legend on the left. b Clonality results for E. faecium. Diamonds represent E. faecium collected from surfaces. Colors represent clonal subgroup membership. Each colored set is a clonal subgroup with fewer than five SNPs different between all members of the group. Unfilled diamonds did not have fewer than five SNPs different with any other isolates. Lineage from BAP is indicated in the legend on the left. For c, d, temporal distances are calculated as +1 for every 2-week span separating isolate collections. Spatial distances are given as +0 if isolates were collected from the same surface and room, +1 if they were collected from the same room, but different surfaces, and +2 if they were collected from different rooms. c Temporal linkage for A. baumannii clones. The expected temporal distance distribution is shown in blue and the observed temporal distribution is shown as a solid black line. d Spatial linkage for A. baumannii clones. The expected spatial distance distribution is shown in blue and the observed spatial distribution is shown as a solid black line. e Temporal linkage for E. faecium clones. The expected temporal distance distribution is shown in red and the observed temporal distribution is shown as a solid black line. f Spatial linkage for E. faecium clones. The expected spatial distance distribution is shown in red and the observed spatial distribution is shown as a solid black line. Source data for all panels are provided in the source data file
