- Amino acid diversity and selection in ESAG sequences from three trypanosomatid protozoa. The BES loci studied are indicated on the left. The strains are Trypanosoma brucei gambiense DAL 972 (T.b.g.), T. b. brucei EATRO 2340 (T.b.r.) and T. equiperdum STIB 818 (T. eq.). N° seqs. = number of protein sequences in alignment; codons = number of codons in gap-stripped alignment; % S = percentage of polymorphic sites; π = average pairwise amino acid diversity; dN/dS ratio ω > 2 = number of amino acid residues with dN/dS ratio (ω) estimated to be greater than 2 indicating evidence for positive selection; Average dN/dS ω (avg.) = average ω estimate over residues with ω > 2.
