The giant liver fluke, Fascioloides magna, is a veterinary important liver parasite of free living and domestic ruminants. This originally North American parasite was introduced along with its cervid hosts to Europe where it has established three permanent natural foci - in northern Italy, central and southern parts of the Czech Republic and the Danube floodplain forests. The first record on fascioloidosis in Poland originated from the Lower Silesian Forest in south-western Poland and since then an occurrence of F. magna in this country has not been documented. Recently, the parasitological examination of red deer (Cervus elaphus elaphus) from the Lower Silesian Wilderness (south-western Poland) revealed the presence of F. magna eggs. In order to determine the genetic interrelationships of the Polish giant liver fluke individuals, they were molecularly analyzed by mitochondrial cytochrome c oxidase subunit I (cox1) and nicotinamide dehydrogenase subunit I (nad1) and compared with haplotypes of so far studied European populations of the parasite. The study revealed the genetic uniformity of F. magna specimens from Poland with part of individuals from the Czech natural focus.
