Southern hybridization analysis for determination of the location of gnr gene. (A) Southern hybridization analysis of plasmid or chromosomal DNAs targeting gnrS gene. Lane 1, Positive control for qnrS gene; Lane 2 or 5, plasmid DNAs from environmentally isolated E. coli and A. punctata, respectively; Lane 3 or 4, chromosomal DNAs from environmentally isolated E. coli and A. punctata, respectively. (B) Southern hybridization analysis of plasmid DNAs from eight environmentally isolated C. fruendii targeting gnrB gene. (C) Southern hybridization analysis of chromosomal DNAs from eight environmentally isolated C. fruendii targeting gnrB gene.
