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.

Paragonimus heterotremus Chen et Hsia, 1964 (Digenea: Paragonimidae): species identification based on the biological and genetic criteria, and pathology of infection.

As a result of the experimental infection of rats with metacercariae of Paragonimus heterotremus Chen et Hsia, 1964 from crabs (Potamiscus tannanti) caught in Yen Bai province, Vietnam, it was found that worms migrated into the lungs, to the liver and less frequently to the tissue that lines body cavities of the hosts, where they reached the adult stage, but in the muscles, worms stayed at the larval stage. Studies have shown that for P. heterotremus, rats can simultaneously play the role of the final and paratenic host; herewith, an infection with the trematode of this species can lead to the development of three forms of paragonimiasis: pulmonary, hepatic and muscular.

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.

Description of a new species, Cryptocotyle lata sp. nov., and discussion of the phylogenetic relationships in Opisthorchioidea.

Adult Cryptocotyle lata sp. nov. worms were obtained from experimental studies.

Morphometric and molecular analyses of Carassotrema koreanum Park 1938 and Elonginurus mugilus Lu 1995 (Digenea: Haploporidae) Srivastava, 1937 from the Russian Far East and Vietnam.

Adult worms that belong to Carassotrema Park 1938 and Elonginurus Lu, 1955 were found in the intestine of Carassius gibelio Bloch, 1782 from the southern Russian Far East and Mugil cephalus Linnaeus, 1758 from northern Vietnam, respectively. Morphometric parameters, geographic location and host species composition of these worms correspond to Carassotrema koreanum Park 1938, which is a known parasite of cyprinid fish in Korea, Japan and China, and Elonginurus mugilus Lu, 1955, first described from M. cephalus in China.

Trematode diversity in freshwater fishes of the Globe I: 'Old World'.

In this paper, we review, continent by continent, the trematode fauna of freshwater fishes of the 'Old World', a vast area consisting of the Palaearctic, Ethiopian, Oriental and Australasian zoogeographical regions. Knowledge of this fauna is highly uneven and clearly incomplete for almost all regions, sometimes dramatically so. Although the biggest problem remains the completion of the 'first pass' of alpha taxonomy, there are in addition great problems relating to biogeography and elucidation of life-cycles.

Hemozoin is a product of heme detoxification in the gut of the most medically important species of the family Opisthorchiidae.

Many species of trematodes such as Schistosoma spp., Fasciola hepatica and Echinostoma trivolvis are blood-feeding parasites. Nevertheless, there is no consensus on the feeding habits of the family Opisthorchiidae (Opisthorchis felineus, Opisthorchis viverrini and Clonorchis sinensis).

Molecular evidence of cryptic diversity in Paracaryophyllaeus (Cestoda: Caryophyllidea), parasites of loaches (Cobitidae) in Eurasia, including description of P. vladkae n. sp.

Molecular phylogenetic analysis of an extensive collection of monozoic tapeworms of the genus Paracaryophyllaeus Kulakovskaya, 1961 (Cestoda: Caryophyllidea), parasites of loaches (Cypriniformes: Cobitidae) in Eurasia, has revealed cryptic species diversity within this long-time monotypic genus, especially in the Paracaryophyllaeus gotoi (Motomura, 1927) species complex [syn. Paracaryophyllaeus dubininorum (Kulakovskaya, 1961); type species]. Three independent, well-supported clades were discovered on the basis of molecular data: (i) specimens from Misgurnus anguillicaudatus and Cobitis lutheri from China, Russian Far East and Japan - called herein P.

Genetic diversity of Clonorchis sinensis (Trematoda: Opisthorchiidae) in the Russian southern Far East based on mtDNA cox1 sequence variation.

We examined the phylogeography and the variation of the mitochondrial DNA (mtDNA) cytochrome c oxidase subunit 1 gene (cox1) of the Chinese liver fluke Clonorchis sinensis (Cobbold, 1875) in two geographic localities in the Russian southern Far East and compared them with those from different geographical regions (China, Korea, Japan and Vietnam). The Russian samples differed from those of the other regions in haplotype frequencies, haplotype and nucleotide diversities, and AT/GC ratios. Only 4 of the 18 haplotypes were common to Russian and Chinese samples, and two haplotypes were common to Russia and other regions.

New data on the morphology of some Far-Eastern species of Rhabdochona (Nematoda: Rhabdochonidae), as revealed by SEM observations.

Specimens of the nematode genus Rhabdochona Railliet, 1916 (Rhabdochonidae) were collected during helminthological examination of four species of cyprinid fishes in two rivers of the Amur River basin in the Russian Far East (Primorsky Region) in June 2011. Detailed light microscopical (LM) and scanning electron microscopical (SEM) examinations (the latter used for the first time for the reported nematode species) of the available material revealed the presence of three inadequately described nominal species of this genus: R. (Rhabdochona) denudata (Dujardin, 1845) from the spotted steed Hemibarbus maculatus Bleeker (Gobioninae), and R.
