Neighbor-joining maximum composite likelihood phylogenetic tree of partial sequences of Tritrichomonas foetus and T. suis internal transcribed spacer 1 (partial), 5.8S ribosomal RNA gene (complete), and internal transcribed spacer 2 (partial). Pentatrichomonas hominis was used as an outgroup. The numbers on the nodes indicate the bootstrap support from 1000 replications. Only bootstrap values of >50 are shown. The scale bar represents the number of substitutions per nucleotide
