Circular structures of chromosome and plasmids harboring blaIMP-1 and mcr-9. a Map of the plasmids pA2483mcr-9 and pA2504mcr-9, showing that, relative to pA2483mcr-9, a pA2504-mcr-9 had a deletion of 11,770 bp from nt 146,310 to nt 158,080. b Map of the plasmids pA2483imp-1 and pA2504imp-1, showing that their structures were identical. c Map of the chromosome of A2563 coharboring blaIMP-1 and mcr-9. The two outermost circles show forward (light blue) and reverse (dark blue) genes and the innermost circle show GC content, with dark orange indicating above average and light orange indicating below average. Colored arrows indicate the positions and directions of antibiotic resistance genes (pink), surrounding genes (light grey) and insertion sequences (dark grey). Truncated genes are indicated by ∆
