Method for regulated expression of single-copy efflux pump genes in a surrogate Pseudomonas aeruginosa strain: identification of the BpeEF-OprC chloramphenicol and trimethoprim efflux pump of Burkholderia pseudomallei 1026b

Antimicrob Agents Chemother. 2006 Oct;50(10):3460-3. doi: 10.1128/AAC.00440-06.

Abstract

Construction and integration of recombinant mini-Tn7 expression vectors into the chromosome of a surrogate, efflux-sensitized, and biosafe Pseudomonas aeruginosa host was validated as a generally applicable method for studies of uncharacterized bacterial efflux pumps. Using this method, the Burkholderia pseudomallei bpeEF-oprC operon was shown to encode a chloramphenicol and trimethoprim efflux pump.
