Neighbor-joining phylogenetic tree of the B. globosus and B. truncatus haplotypes collected in Madziwa, Zimbabwe, in relation to other Bulinus species. Each terminal bar is marked using the species name and the code given to the haplotype, e.g. H1 or T1. Bulinus globosus and B. truncatus haplotypes are represented by the letter H and T, respectively. The bootstrap values below 80% are not shown. The accession numbers of the individual sequences forming the haplotypes are shown in Additional file 1: Table S3
