Fig. 3 in Trypanosoma madeirae sp. n.: A species of the clade T. cruzi associated with the neotropical common vampire bat Desmodus rotundus

Fig. 3. Phylogenetic positioning of T. rotundus in the clade T. cruzi. ML phylogenetic analysis based on the concatenated sequences of V7V8 SSU rRNA and gGAPDH genes (1.690 characters, –Ln = 8768.346166) from ten isolates of T. rotundus, other 29 bat trypanosomes, and 21 trypanosomes from other mammals. T. lewisi was used as outgroup. The numbers at the nodes correspond respectively to P, ML (500 replicates) and BI support values.
