A new paper with Lindsay Sonnenkalb as first-author has just been published in The Lancet Microbe. It is a collaboration between a  number of groups, led by Stefan Niemann and in it we evolved resistance to bedaquiline in vitro. Sequencing revealed 265 genetic variants with 250 affecting Rv0678, which is the transcription regulator of mmpL5, an efflux pump. These variants included a number of novel mutations and, interestingly, a large scale rearrangement of Rv0678 which was confirmed with PacBio sequencing.
