Electrophoresis (a) and Southern blot (b) of isolates carrying bla OXA-72. The pattern of plasmid electrophoresis and Southern blot was very similar among isolates. However, Southern blot revealed bla OXA-72 in isolate 1765 (arrow) may be located in a different genetic background. All isolates were tested but only the results of 15 isolates (from Lane 1 to 15) were presented. M, marker (Bio-1KBTM Mass DNA Ladder, Protech Technology Enterprise Co., Ltd, Taiwan).
