Fig 2. Phylogenetic relationships of bulinids based on concatenated cox1 + 16S sequences.

Phylogenetic relationships of bulinids from this study and from GenBank based on 1163 bp of combined cox1 and 16S sequences inferred from ML analysis under the GTR+G+I model. Bootstrap values above 95 are indicated by an asterisk. Sequences generated during this study are listed by MSB:Host number. Additional information for specimens can be found in Table 1. Specimens recovered within the LVB by this study are color coded by species. B. africanus group species are in warm colors, B. forskalii group species in greens, and B. truncatus/tropicus group species in blues. Wave icons indicates species found within Lake Victoria. Cow icons indicate species with naturally occurring S. bovis infections. Human icons indicate species with naturally occurring S. haematobium infections.
