The second is plasmid-mediated resistance, which results from extrachromosomal elements that encode proteins that disrupt quinoloneenzyme interactions, alter drug metabolism, or increase quinolone efflux.
Resistance mechanisms may also be acquired through horizontal gene transfer of mobile genetic elements on plasmids (circular pieces of extrachromosomal DNA) that carry the resistance gene(s) between bacteria.[2] A bacterium that possesses a way of resisting an antibiotic attack has a survival advantage over bacteria that do not.
