Table 3. Distribution of Giardia duodenalis assemblages A and B subtypes identified by gdh PCR amplification and terminal-RFLP for 32 samples (27 participants) collected from children living in a remote Indigenous community in the Northern Territory.

*BIII and BIV subtypes represent two assemblage B gdh genotypes that were identified in this study, and were consistent with the previously described gdh BIII and BIV subassemblages [14].
