Figures & Tables

Line drawing of the trematode species commonly found in the intestines of cormorants: a – Petaseiger exaeretus, b – Petasiger radiatus, c – Petasiger phalacrocoracis, d – Hysteromorpha triloba. Scale bars: a, d – 200 μm; b, c – 500 μm.

Phylogenetic analysis by maximum likelihood estimation of Petasiger (a) Hysteromorpha (b) and Metorchis (c) samples with related sequences deposited inGenBank. Samples from the present study are in bold. The scale bar indicates the expected number of substitutions per site.
