Metacestodes found in roe deer and moose. 2A: metacestode isolated from the omentum of a roe deer from the Węgrów region; 2B: metacestode isolated from the liver of a roe deer from the Rawa Mazowiecka region; 2C: metacestodes isolated from the omentum of a roe deer from the Iłża region; 2D: metacestodes isolated from the mesentery of a moose from the Biebrza National Park

Maximum-likelihood phylogenetic analysis of the cytochrome c oxidase subunit 1 (cox1) data (776 bp) for Taenia hydatigena metacestodes found in roe deer and moose in Poland (model = General Time Reversible, GTR+I (invariant sites) +G (Γ distribution)). Branch support estimated using nonparametric bootstrap analyses based on 1,000 replicates. The outgroup was Taenia lynciscapreoli. Two-letter, six-number codes are GenBank accession numbers. Sequences obtained in this study are shown in bold. TR – originating in Türkiye; GH – originating in Ghana; PL – originating in Poland; CN – originating in China; BNP – Biebrza National Park; WE – Węgrów region; IL – Iłża region; RA – Rawa Mazowiecka region; PNP – Polesie National Park; KNP – Kampinos National Park
