Figure 2

Neighbour-Joining (NJ) tree for 16 species-level lineages within the ' revolutum ' group of Echinostoma based on the mitochondrial gene nad 1: Clade B and the remaining species, continuation of Figure 1 . The newly-sequenced European isolates are shown in red; stars indicate adult isolates from natural infections. Sequence identification is as in GenBank, followed by a letter: D, Detwiler et al. [16,17]; G, Georgieva et al. [19]; K, Kostadinova et al. [28]; M, Marcilla et al. (unpublished); M & B, Morgan & Blair [14,26]; O, Olson et al. [47]. The scale-bar indicates the expected number of substitutions per site.
