Fig. 2From: Multi-host infection and phylogenetically diverse lineages shape the recombination and gene pool dynamics of Staphylococcus aureusPrincipal component analysis (PCA) of the S. aureus accessory genome. PCA based on the presence or absence of accessory genes, with dots representing isolates colored according to host (a) and according to ST (b). For visual clarity, only the three dominant STs (ST5, ST8, ST30) are colored. PC1 and PC2 are principal component 1 and principal component 2, respectivelyBack to article page
