Аннотация
In this study, we analyze the diversity of flagellated protozoa Diplomonadida, which are parasites in the digestive system of animals, in fishes of East Siberia. We have developed a method to diagnose the presence of DNA of Diplomonadida representatives, in particular, of Spironucleus barkhanus, in the analyzed samples. In our previous studies, we used molecular genetic methods to analyze salmonids of East Siberia for the presence of diplomonads and to determine the infection. The analysis of genetic diversity of diplomonads in the fishes of the genera Coregonus and Thymallus revealed the presence of one species, S. barkhanus. However, in addition to a cosmopolitan genotype widespread among Holarctic salmonids, in C. migratorius and C. lavaretus baicalensis, we have found a new genotype obviously different from those registered previously. Probably, S. barkhanus of this genotype is endemic for Lake Baikal. To determine a probable parasite exchange between C. migratorius and other fish species in the pelagic zone of Lake Baikal, we performed a screening of near-shore pelagic and pelagic cottoid fish for the presence of S. barkhanus. The analysis did not indicate the presence of DNA of S. barkhanus in the studied samples. We suppose the presence of other diplomonads species in endemic cottoid fish different from S. barkhanus.
