aac(6')-Ib-cr is the most prevalent plasmid-mediated fluoroquinolone (FQ) resistance mechanism in Enterobacteriaceae. We aimed to analyse the interplay between this plasmid-mediated gene and chromosomal-mediated quinolone resistance mechanisms on both FQ resistance and bacterial fitness in Escherichia coli.
