  1. a % reported is the proportion of virus quasispecies that did not have an amino acid substitution within the Gag p11C epitope (remained wild type).
  2. b In parentheses is the number of virus quasispecies that remained wild type at the Tat TL8 epitope/number of virus quasispecies sequenced.
  3. c ND = not done or unable to amplify virus variants
