Figure 2From: Conjugative IncFI plasmids carrying CTX-M-15 among Escherichia coliESBL producing isolates at a University hospital in Germany Agarose gel showing S1 nuclease PFGE-based sizing of large plasmids for 8 isolates. M (Lambda Marker) indicates the molecular weight marker of concatenated multimers of the bacteriophage lambda genome. Plasmid preparations from isolate number 48, 67, 79, 90, 58, 70, 110 and 112 reveal plasmids with sizes ranging from 45.5 kb to 194 kb which are indicated with arrows.Back to article page
