Genetic and geographical relationships of H. taeniaeformis s.s. isolates based on a neighbor-joining analysis of the nad4 locus. The relationships were inferred by a neighbor-joining analysis of the nad4 gene sequences of H. taeniaeformis s.s. isolates from different countries based on genetic distance calculated using the Kimura 2-parameter model. The numbers on the branches are percent bootstrapping values from 1,000 replicates. Each H. taeniaeformis s.s. sequence is identified by its accession number and geographical location (country). Novel nucleotide sequences obtained in the present study are represented by black triangles.
