Bayesian inference phylogram reconstructed using partial 28S rDNA sequences for nine Echinostoma spp. The alignment comprised 1,219 nucleotide positions. Outgroups: Hypoderaeum conoideum and Echinoparyphium cinctum. The newly-sequenced European isolates are shown in red. Sequence identification is as in GenBank, followed by a letter: G, Georgieva et al. [19]; O, Olson et al. [47]; L, Lotfy et al. [49]; M, Mollaret et al. [50]. The scale-bar indicates the expected number of substitutions per site.
