Fig. 2From: Molecular epidemiology of bla OXA-23 -producing carbapenem-resistant Acinetobacter baumannii in a single institution over a 65-month period in north ChinaResults of plasmid measurement and hybridization. a S1 nulcease digestion of total DNA of A.baumannii isolates was followed by PFGE. Plasmid bands are shown as linearized fragments on the gel. For each A.baumannii ST, only one strain was selected randomly for this assay. b Southern blot hybridization for the bla oxa-23 gene.
