Phylogenetic tree of concatenated SSU-rRNA and LSU-rRNA sequences of badger trypanosomes and comparator species. The phylogenetic analysis was implemented using the Maximum Likelihood method based on the Kimura 2-parameter model. The tree with the highest log likelihood (−4361) is shown. Initial trees for the heuristic search were obtained automatically by applying Neighbor-Join and BioNJ algorithms to a matrix of pairwise distances estimated using the Maximum Composite Likelihood (MCL) approach, and then selecting the topology with the superior log likelihood value. A discrete Gamma distribution was used to model evolutionary rate differences among sites (5 categories (+G, parameter = 0.1323)). The analysis involved 26 nucleotide sequences, 11 of which, used the concatenated datasets (T. grosi, T. otospermophili, T. kuseli, T. rangeli, T.pestanai, T. rotatorium, T. simiae, T. congolense (riverine forest), T. congolense (kilifi), T. congolense (savannah), Trypanoplasma borreli and badger trypanosome). There were a total of 1560 positions in the final dataset. The numbers after species name on branch are the GenInfo Identifier number (GI) while annotated colours indicate different groups of kinetoplastids. Evolutionary analyses were conducted in MEGA6.
