Circular map of the A. baumannii ZS3 genome and the gene environment of multiple copies of blaTEM-1D and ISAba1-ampC. The genome of A. baumannii ZS3 is represented by the outer blue circle. The GC content is represented by the black circle, and the GC skewed circle is the inner circle represented in green and purple. Blue arrows, coding sequences (CDS); red arrows, resistance genes; yellow rectangles, insertion sequence (IS) structures; pink arrows, Tn3 structures; gray arrow, IntIPac. The blaTEM-1D repeat fragment is highlighted with a black frame.
