Figure 2. Neighbour-joining tree based on partial nucleotide sequences of the TPI gene of Giardia intestinalis, including our new sequence (underlined).

Genotypes previously found in apes and humans are shaded. The host is listed for each sample. Values on branches are percent bootstrapping using 1 000 replicates. The bootstrap proportions greater than 50% are shown on each branch. Nucleotide sequences generated from this study are underlined and are deposited in the GenBank under Accession Nos. JQ837803-JQ837808.
