Population snapshot of MRSA strains from blood source in the MLST database. Individual sequence type (ST) is highlighted in black (STs in the database), green (STs in this study) and pink (STs in both the database and in this study) and is represented by each circle. The size of the circle indicates the frequency of a particular ST and the colour of the circle represents founders or subgroup founders. Blue circles are ‘founders’ [defined as ST with many single locus variants (SLVs) and is prevalent within a CC], whereas yellow circle are ‘subgroup founders’. The most prevalent ST in this study was ST239, which is the subgroup founder within CC8
