Fig. 1: Plasmid antimicrobial resistance gene profiles.

A block of light brown indicates the presence of one of the 33 different ARGs on the plasmid. The inner ring describes each plasmid by name and is coloured by group. Indicative plasmids with no ARG (only black blocks present) are included to demonstrate the presence of related plasmids with no ARGs. The phylogenetic tree shows the relatedness of the plasmids. Most plasmids contained more than one ARG and were predominantly MDR plasmids.
