Molecular Analysis of VanA Outbreak of Enterococcus faecium in Two Warsaw Hospitals: The Importance of Mobile Genetic Elements

Figure 2

PFGE-based dendrogram of selected isolates from outbreaks in IO and IH, representing all PTs. Normalization performed by the use of reference Lambda Ladder PFG Marker (New England BioLabs, UK). The phylogenetic tree was constructed by the use of Dice coefficient (optimization, 0.5%; band tolerance, 1.3%) and UPGMA clustering.
