ABSTRACT
In this work, for the first time, the genetic variability of the Metagonimus suifunensis population in the Russian southern Far East was estimated based on the full-length sequences of the nad1 gene of mitochondrial DNA. In addition, for a sample of the same size, the sequences of cox1 and cytb genes, previously used for population studies for M. suifunensis, were reanalysed. Three markers were combined to a common sequence, and the obtained data were studied. Despite the higher level of variability, nad1 and cox1 mtDNA genes did not reveal subdivisions within the population. The combined dataset made it possible to determine that the sample from the Odyr River was the centre of the species' range formation and clarified the continental migration route of the parasite from south to north. According to the data obtained, it was presumed that piscivorous birds participate in the life cycle of the parasite. The subdivision within population revealed that using all three mitochondrial markers is consistent with the features of differentiation within populations of related species, but the reasons for its formation remain unclear due to the insufficient amount of data and the use of different markers in studies of different species.
