Identification of clonal clusters among 197 MRSA bacteremia cases. a Beeswarm plot of MRSA cases with sequenced isolate genomes during the surveillance period. Cases with isolates separated by ≤ 15 core-genome SNVs are grouped in clonal clusters, each highlighted with a distinct color. The number of isolates in each cluster is indicated in the color key. b Histogram of pairwise core-genome SNV distances for isolates obtained from the same patient (black bars) and isolates obtained from different patients (gray bars). The vertical red line indicates the 15-SNV threshold for clonality. c Heatmap of pairwise core-genome SNV distances between clustered isolates. Clusters are grouped along the diagonal and colored as in a, with decreasing shading reflecting an increased pairwise SNV distance. Closed squares and open squares are used for isolates from different patients or the same patient, respectively. All date information in this figure was recoded to protect health information.
