Figure 6From: Staphylococcus epidermidis pan-genome sequence analysis reveals diversity of skin commensal and hospital infection-associated isolatesPrincipal components anaylsis of ortholog clustering. The orthologous gene cluster data for 35 genomes was analyzed using principal components analysis. Nosocomial isolates are shown as red circles and ST2 nosocomial isolates are filled red circles. Commensal isolates are black circles. The dashed ovals indicate the phylogenetic groups described in Figure 4 but are not statistically defined. Percentages of variance explained by PC1 and PC2 are 13.8% and 9.1%, respectively.Back to article page
