Clustering by PFGE and phage typing. (A) Unweighted-pair group method using average linkages (UPGMA) dendrogram illustrating the similarity (based on the Dice coefficient) of the PFGE profiles of 25 representative Rhine-Hesse isolates and 5 reference isolates. The similarity scale is shown at the bottom. spa clonal complexes (spa), mec types (mec), and MLST types (ST) seem to be randomly distributed in the Rhine-Hesse cluster. (B) Cluster dendrogram of the phage typing results of 25 representative Rhine-Hesse isolates. Data were analyzed by hierarchical clustering computing distances using the Ward method.
