(A) clonal analysis of the evolution of HIV RAL resistance over time in two patients (from Malet et al., J Antimicrob Chemother 2009). The bars indicate the relative proportion of each mutational pathway within the population of viral clones sequenced. (B) clonal analysis of the evolution of RAL resistance over time in one patient (from Fransen et al., Antimicrob Agents Chemother 2009). The bars indicate the relative proportion of each mutational pathway within the population of viral clones sequenced.
