Figure 1. Pulsed-field gel electrophoresis (PFGE), multiple-locus variable-number tandem-repeat analysis (MLVA), phage types, and number of isolates. *PFGE patterns were sorted using the Pearson correlation in BioNumerics 4.0. †Types are shown when present 6× and when >4 isolates had identical MLVA type within each PFGE type. ‡Phage types are only shown when <2 isolates within each MLVA type had the same phage type.
