Principal Component Analysis of SAC virulence genes. a PCA based on the presence (1) and absence (0) of 106 virulence genes; b PCA based on the mean distance of one strain against the rest 50 strains among 30 core virulence genes. Five genes, sed, see, sej, selr and etb, were excluded from the gene because they were not present in any strain. Species are marked using different colored dots: S. aureus (red), S. argenteus (green) and S. schweitzeri (blue). The cluster of dots representing S. argenteus ST2250 strains is indicated by the arrow. The genes that provide the best strain differentiation are shown in the biplot
