Figure 2. Geographic origin of US hound Leishmania isolates. A) Cladogram of the neighbor-joining tree from Figure 1 showing monophyletic groups for better visibility of evolutionary relationships of the US hound parasites. B) Cladogram of the maximum-likelihood phylogeny (Appendix 2 Figure 2, panel B). Cladograms were reconstructed on the basis of whole-genome genotype calls of 83 parasite samples representing the dominant L. infantum zymodeme MON-1 from the United States, Europe, South America, and the Middle East, which were the samples most relevant in the context of the origin of the US samples (Appendix 2 Figure 2). Numbers at internal nodes show bootstrap values.
