Relationship between CC and ST for Mycoplasma pneumoniae isolates by eBURST version 3.1 analysis (http://eburst.mlst.net/v3/mlst_datasets/). Data included 417 strains from Japan, 2002–2016, and 62 strains isolated from the United Kingdom, the United States, China, and France. For all isolates, 24 STs were identified. The size of each circle is proportional to the number of isolates for each ST. Red indicates isolates detected in Japan only; blue indicates isolates detected in the United Kingdom, the United States, China, and France but not Japan; black indicates isolates detected in all 5 countries. CC, clonal complex; ST, sequence type.
