Phylogenetic tree depicting evolutionary relationships among Giardia duodenalis sequences at gdh from Brazilian human and animal isolates. The analysis was inferred using the Neighbor-Joining method of the nucleotide sequence covering a 388-bp region (positions 80–467 of GenBank: L40508) of the gene. Bootstrap values lower than 50% are not shown. Red circles represent sequences generated in the present study; black circles represent reference sequences downloaded from the GenBank database. Spironucleus vortens was used as the outgroup
