Circular maps representing comparisons of blaSHV-12 (p33 and p39)-carrying plasmids available at GenBank and plasmids assembled in this study. The innermost rings (not colored black) represent the top plasmids with high nucleotide identity and coverage with respect to reference plasmids (p33 and p39). The legends at the top left present plasmid name, country, animal species/human, and year of isolation, where available. Areas of the plasmids carrying AMR genes are presented in the outermost rings. AMR genes, genes associated with mobile elements, and virulence genes are colored and labeled in red, blue, and green, respectively.
