Fig. 4From: Prevalence of intestinal parasites and molecular characterization of Giardia intestinalis, Blastocystis spp. and Entamoeba histolytica in the village of Fortín Mbororé (Puerto Iguazú, Misiones, Argentina)Phylogenetic relationships of Giardia intestinalis inferred by neighbor-joining analysis of the β-giardin nucleotide sequences. Filled triangles represent reference sequences obtained from GenBank, described in Additional file 2: Table S2. A sequence from Giardia muris was used as the outgroup. Bootstrap values are based on 500 replicates, and only bootstraps > 50% are indicatedBack to article page
