Figure 2Drug accumulation in isogenic strains with and without the efflux gene cluster. Energy-dependent efflux of [3H]chloramphenicol (
a) and [14C]salicylate (
b) by
B. cepacia. Strains 249-2(pAM1) (filled squares) and 249-2(pSP329) (open circles) were assayed for accumulation of radiolabel before and after the addition of 250 μM CCCP. The addition of CCCP increased cell-associated accumulation of both drugs (i.e., decreased drug efflux) in 249-2(pAM1). Data points represent the means of three experiments with error bars showing the SD.
