Plasmid profile of sewage wastewater bacterial isolates: lane 1, E. coli ST2; lane 2, E. coli ST3; lane 3, E. coli ST4; lane 4, E. coli ST4 (cured strain); lane 5, E. coli V517 (≈54 kb) standard molecular marker; lane 6, A. baumannii ST1; lane 7, P. putida ST6; lane 8, P. putida ST6 (cured strain). Note the presence of chromosomal DNA smears and the absence of plasmid DNA bands in cured bacterial strains (lanes 4 and 8).
