Polymorphism of fragments of the ND1 and CO1 mitochondrial genes was for the first time found in four liver fluke Fasciola hepatica samples from Ukraine, Belarus, Moscow region, and Mordovia. The ND1 and CO1fragments were respectively 292 and 433 bp in size, with polymorphic sites amounting to 2.7 and 0.9% of the total sequence. Seven haplotypes were found in the four samples; two haplotypes (A and B) were most common (29.1 and 45.8%, respectively) in the pooled sample. The haplotype frequency distribution differed among the four populations. Haplotype B prevailed in the Mordovian and Moscow region samples. In addition, these samples had a higher number of unique haplotypes (A2, A3, B2). The results testify to genetic differences of the four geographically distant populations of F. hepatica.
