Figure 1From: Conjugative IncFI plasmids carrying CTX-M-15 among Escherichia coliESBL producing isolates at a University hospital in Germany PFGE dendogram of ESBL-producing E. coli. Heterogeneity of the 63 E. coli ESBL producers are seen on the dendograms. The diagram also shows the isolate number, PFGE types as well as the corresponding phylogenetic group. The dashed line X indicates SAB of 0.8 revealing six clusters 1–6; PFGE types are labelled X1–X13.Back to article page
