A novel role for colistin as an efflux pump inhibitor in multidrug-resistant Klebsiella pneumoniae [PDF]

Scientific Reports
Antimicrobial resistance (AMR) is a global challenge that demands new strategies to maintain the effectiveness of current treatments. AMR arises through various mechanisms, including overexpression of drug efflux pumps. The AcrAB-TolC efflux pump is used

Efflux pumps positively contribute to rifampin resistance in rpoB mutant Mycobacterium tuberculosis [PDF]

Annals of Clinical Microbiology and Antimicrobials
Background While several recent studies have documented the importance of efflux pumps as mediators of rifampin (RIF) resistance, it remains uncertain which efflux pumps play major roles in rifampin-resistant Mycobacterium tuberculosis strains harboring ...

AcrAB-TolC Efflux Pump Mediated Resistance to Carbapenems among Clinical Isolates of Enterobacteriaceae

Journal of Pure and Applied Microbiology, 2022
AcrAB-TolC is a resistance nodulation division type of efflux pump present in Enterobacteriaceae. It non-specifically effluxes antibiotics out of the bacterial cell, thus conferring drug resistance.
