Population diversity and selection for whole-genome sequencing. Pie charts indicating the percentage of typed MSSA isolates assigned to a particular spa type or MLVA type, categorized by study year (rows) and origin (columns). Raised sections indicate the isolates that were eligible for whole-genome sequencing, which includes all neonatal isolates in 2014. Abbreviations: MSSA: methicillin-susceptible S. aureus; MT: MLVA type; HCW: healthcare worker.
