Morpho-Molecular Features and Phylogenetic Relationships of Oschmarin, 1963 (Trematoda: Opisthorchiidae) from East Asia.

Adult trematodes of the genus were found in the gallbladders of ducklings that had been experimentally fed freshwater fishes of the genera and that were naturally infected by metacercariae. Some of the trematodes were identified as , whose morphology of developmental stages and molecular data had previously been described in detail. The other trematodes were confirmed as species on the basis of morphological features: subterminal oral sucker, vitelline follicles with interrupted bands, and rosette-shaped testes.

Three species of Kobayashi, 1921 (Digenea: Cryptogonimidae) in the East-Asian region: morphological and molecular data.

New data have been obtained for three representatives of Exorchis; Exorchis convictus sp. n., Exorchis oviformis and Exorchis sp.

First next-generation sequencing data for Haploporidae (Digenea: Haploporata): characterization of complete mitochondrial genome and ribosomal operon for Parasaccocoelium mugili Zhukov, 1971.

The first data on a whole mitochondrial genome of Haploporidae, Parasaccocoelium mugili (Digenea: Haploporata: Haploporidae) was generated using the next-generation sequencing (NGS) approach. We sequenced the complete mitochondrial DNA (mtDNA) and ribosomal operon of Parasaccocoelium mugili, intestine parasite of mullet fish. The mtDNA of P.

Morphological and molecular data for highly pathogenic avian parasite Erschoviorchis anuiensis sp. n. and phylogenetic relationships within the Opisthorchiidae (Trematoda).

Adult worms of Erschoviorchis anuiensis sp. n., parasites of the pancreas and liver of birds, were found by feeding the Muscovy ducks Cairina moschata dom.

First description of genetic diversity for the genus Metagonimus using the complete cox1 gene sequence.

The complete cox1 gene sequence was analysed for Metagonimus suifunensis from eight localities in the Russian southern Far East, and the level of variability was compared with that of Clonorchis sinensis from the same territory of Russia. These species belong to the superfamily Opisthorchioidea, have a similar distribution in the Russian southern Far East and share second intermediate and definitive hosts, but are distinguished by their first intermediate hosts belonging to different orders of caenogastropods. The data obtained showed that the nucleotide sequence variability of the M.

The geographical vector in distribution of genetic diversity for Clonorchis sinensis.

Clonorchis sinensis, the causative agent of clonorchiasis, is one of the most important parasites that inhabit countries of East and Southeast Asia. In this study, we validated the existence of a geographical vector for C. sinensis using the partial cox1 mtDNA gene, which includes a conserved region.
