Burkholderia cepacia complex (Bcc) and Burkholderia pseudomallei complex (Bpc) species include pathogens that are typically multidrug resistant. Dominant intrinsic and acquired multidrug resistance mechanisms are efflux mediated by pumps of the resistance-nodulation-cell division (RND) family. From comparative bioinformatic and, in many instances, functional studies, we infer that RND pump-based resistance mechanisms are conserved in Burkholderia. We propose to use these findings as a foundation for adoption of a uniform RND efflux pump nomenclature.
