From reference 20.
Underrepresentation of Indonesian strains in cluster II compared with the representation of Dutch strains in this cluster (P < 0.001).
Overrepresentation of Indonesian strains in cluster III compared with the representation of Dutch strains in this cluster (P = 0.018).
Cluster IVb was significantly enriched with PVL in comparison with the other AFLP clusters (P = 0.022).
Proportionately more PFGE cluster A strains compared with the other PFGE cluster strains (P < 0.001).
Proportionately more PFGE cluster B strains compared with the other PFGE cluster strains (P < 0.001).
