Neighbor-Joining tree of the gdh Giardia sequences. Two sequences from the present study (in bold) and 12 reference sequences representing assemblage/sub-assemblages A/AI, A/AII, A/AIII, B/BIII, B/BIV and assemblage E were included in the analysis for comparative purposes. Accession numbers of publicly available reference sequences are indicated. The evolutionary distances were computed using the Tamura 3-parameter method and a bootstrap test based on 1000 replicates. Bootstrap values at nodes <70 are not indicated
