Biliary parasite Pseudamphistomum truncatum (Opistorchiidae) in American mink (Mustela vison) and Eurasian otter (Lutra lutra) in Ireland.

Native Eurasian otter (Lutra lutra) and introduced American mink (Mustela vison) carcasses collected throughout Ireland were screened for biliary parasites. Secondary intermediate hosts, Cyprinid fish, were also examined for Opistorchiid metacercariae. Twenty-nine mink and 24 otter gall bladders were screened for biliary parasites.
