Figure 4. Maximum-likelihood phylogenetic tree based on 18S–28S rRNA sequences of schistosomes. Schistosomatids are indicated in the large box and the Bilharziella, Trichobilharzia, Gigantobilharzia, and Dendritobilharzia (BTGD) clade is indicated in the gray box. Samples in boldface are those obtained from Haminoea japonica snails. Node support is indicated by maximum parsimony (MP) and minimum evolution (ME) bootstrap values and Bayesian posterior probabilities (PPs), respectively. Asterisks indicate MP and ME bootstrap values >85 and PPs >98 and hyphens indicate no significant node support. Branch support is designated only for major clades. Scale bar indicates nucleotide substitutions per site.
