9) Resistance can also be acquired by minimizing the accumulation of the antimicrobial agent in the cell by either one or both of the following mechanisms: altered expression of porins leading to decreased penetration of fluoroquinolones within bacteria or increased efflux of quinolones from the bacterial cell due to overexpression of the AcrAB-TolC efflux pump that acts synergistically with the outer membrane mutation.
