Fig. 2.

Phylogenetic tree based on 18SrRNA genes sequences of Trypanosoma vivax isolates (Brazil, Nigeria and Mozambique), Trypanosoma evansi, Trypanosoma theileri, Trypanosoma cruzi, Babesia bigemina and Babesia bovis. Sequences were compared using the unweighted pair group method with arithmetic mean (UPGMA). The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (1000 replicates) is shown next to the branches. The scale bar represents the number of mutations per sequence position.
