Figure. Pulsed-field gel electrophoresis (PFGE) pattern and phylogenetic tree of 4 strains ST377. SmaI macrorestriction patterns were digitized and analyzed by using GelCompar II (Applied Maths, Kortrijk, Belgium) to calculate Dice coefficients of correlation and to generate a dendrogram by the unweighted pair group method using arithmetic averages clustering. The scale indicates the level of pattern similarity. PVL, Panton-Valentine leukocidin; ST, sequence type.
