Multidrug efflux pumps play an important role in bacterial multidrug resistance by actively excreting antibiotics. The ATP‐binding cassette–type drug efflux pump MacAB was originally reported as a macrolide‐specific pump. MacAB is also known to be required for the virulence ofSalmonella entericaserovar Typhimurium following oral infection in mice. Here, we performed a screening of inhibitors ofSalmonellaMacAB and found a compound that increased the susceptibility of a MacAB‐expressing strain to macrolides. It was previously reported that MacAB is required to resist peroxide‐mediated killingin vitroand that a supernatant of wild‐typeSalmonellarescues the growth defect of amacABmutant in H2O2. In this study, we also found that the MacAB inhibitor reduced the ability of the supernatant to rescueSalmonellacells in H2O2. This compound could lead to a better understanding of the function of MacAB.
