Phylogenetic relationship among multi-locus sequence subtypes of Giardia duodenalis assemblage B from this and previous studies as inferred by a neighbor-joining analysis of concatenated sequences of the gdh, bg, and tpi loci, based on genetic distances calculated by Kimura 2-parameter model. Bootstrap values greater than 50 % from 1,000 replicates are shown. The four specimens from cats in this study are indicated by filled triangles
