Variation in the triosephosphate isomerase (TPI) nucleotide sequences of G. duodenalis isolates belonging to the assemblage B. Twelve distinct subtypes of G. duodenalis based on the these sequences were evident within assemblage B. The isolates representing these subtypes (S1–S12) as follows: S1 (341, 2578, 2579, 2580, 2586, 2587, 2879, 2890, 2895, 2920, 2924, 2926, 2935, 4599, 4600); S2 (2582, 2583, 2589, 2932); S3 (2506, 2536, 2917); S4 (2590, 2887, 2913, 2915, 2930); S5 (2902); S6 (2877); S7 (2900); S8 (2901); S9 (1653, 1654, 1655, 3469, 3470, 3495, 3500, 3518, 3599); S10 (3565, 3569); S11 (3577); and S12 (1758). Dots denote sequence identity to GenBank accession no. L02116; dashes denote sequence information not obtained.
