Figure 7. Maximum-likelihood tree of Taenia saginata tapeworm strains and T. asiatica tapeworms inferred from short fragments (426 nt) of the cytochrome c oxidase subunit 1 gene. The northern strain of T. saginata tapeworm is represented by the Gydan isolate from northern Siberia, Russia. T. crocutae tapeworm was used as an outgroup. Number along branch indicates a bootstrap percentage. GenBank accession numbers of original sequences are shown in parentheses. Scale bar indicates nucleotide substitutions per site.
