Comparison of MICs for different antimicrobials between genetically related (i.e., isolates in cgMLST clusters) and unrelated EIA-MRSA isolates. (A) Distribution of MICs in genetically related (black dots) and unrelated (grey dots) EIA-MRSA isolates across different antimicrobials. (B) Minimum spanning tree based on the core genome of 105 EIA-MRSA isolates. Node colors represent the clonal complex (CC). Thirteen cgMLST clusters, each with at least two isolates and a maximum of eleven allelic differences, are highlighted with a grey background. Dashed outlines around nodes indicate isolates resistant to levofloxacin. Allelic differences between two isolates are indicated on the edges. ST764 and ST22 isolates are enclosed in boxes
