Figure 2
PCA of the 1,056 S. aureus strains. The different cubes (plotted in 3D space), colored according to the source, represent every strain in the study. Each axis represents the score calculated for that strain on each PC. The distribution of the strains is shown from 2 different angles (A and B). The 5 circles indicate the different phylogenetic AFLP clusters.
