Figure. Principal component analysis of amplified fragment length polymorphism (AFLP) data of 1,033 Staphylococcus aureus strains. The different cubes (plotted in 3-dimensional space) represent every strain in the study. Each axis represents the score calculated for that strain on each principle component. The 4 circles indicate the different genetic AFLP clusters. Cluster IV could be subdivided in 2 minor clusters (8). The percentages (below each cluster) indicate the relative number of Panton-Valentine leukocidin (PVL)-positive strains in each major AFLP cluster. The single PVL-positive strain in cluster III is not visible behind the gray cubes. Gray, PVL-gene negative; red, PVL-gene positive. |
