Phylogenteic relationship of Fasciola parasites based on sequences of COI.

Paragonimus westermani (AF219379) was used as an outgroup. Evolutionary relationships of 12 taxa was inferred using the maximum likelihood method based on Tamura-Nei model (Tamura & Nei 1993) with Invariant sites (I). The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (2000 replicates) are shown next to the branches (Felsenstein, 1985). Phylogenetic analyses were conducted in MEGA5 (Tamura et al., 2011).
