The invasive monozoic tapeworm Atractolytocestus huronensis, a specific parasite of common carp, was originally found and described in the North American continent. In the current study, tapeworms from one North American (USA) and five European localities (United Kingdom/UK, Slovakia, Hungary, Croatia, and Romania) were subjected to molecular analyses in order to determine the level of intrapopulation and intraspecific molecular variation and to assess interrelationships among American and European populations of the parasite. Partial sequences (672 bp) of the mitochondrial cytochrome c oxidase subunit I (cox1) revealed the presence of only two cox1 haplotypes. Both haplotypes differed in three nucleotide positions (99.6% identity) which did not change the amino acid sequence. The cox1 data imply that introduction of the parasite to Europe was probably the result of 2 independent events directed to the UK and Continental Europe.
