Agarose gel electrophoresis patterns of plasmid DNA from SGAr S. aureus clinical isolates carrying vatA-vgbA (lanes C to J). (A) Plasmid migration patterns; (B) hybridization patterns with the vgbA probe (pIP1654). Lanes A, the Raoul marker (Appligene) used as a standard; lanes B, total DNA from BM3093; lanes C, plasmid DNA from genotype 22a strain (Paris-A, 1998); lanes D, plasmid DNA from genotype 36a strain; lanes E, plasmid DNA from genotype 8a strain; lanes F, plasmid DNA from genotype 32 strain; lanes G, plasmid DNA from genotype 3 strain; lanes H, plasmid DNA from genotype 19 strain; lanes I, plasmid DNA from genotype 20 strain; lanes J, plasmid DNA from genotype 16a strain.
