Ups and downs of infections with the broad fish tapeworm Dibothriocephalus latus in Europe (Part II) and Asia from 1900 to 2020.

The broad fish tapeworm, Dibothriocephalus latus (Diphyllobothriidea), is the most important causative agent of diphyllobothriosis, a fish-borne zoonosis, in Europe. Part I of this review focused on the occurrence of D. latus in northwestern and central Europe, particularly in Fennoscandia, the Baltic, the Alpine lakes and Danube River regions during 1900-2020.

Bird Louse Flies spp. (Diptera: Hippoboscidae) as Potential Vectors of Mammalian and Other Pathogens.

Birds and mammals share various ectoparasites, which are responsible for the transmission of a wide range of pathogens. The louse flies (family Hippoboscidae) are ectoparasitic dipterans feeding strictly on the blood of mammals and birds. Both sexes of the louse flies are obligatory hematophagous and are known to act as the vectors of infectious agents.

An examination of nervous system revealed unexpected immunoreactivity of both secretory apparatus and excretory canals in plerocercoids of two broad tapeworms (Cestoda: Diphyllobothriidea).

and are diphyllobothriidean tapeworms autochthonous to Europe. Their larval stages (plerocercoids) may seriously alter health of their intermediate fish hosts () or cause intestinal diphyllobothriosis of the final human host (). Despite numerous data on the internal structure of broad tapeworms, many aspects of the morphology and physiology related to host–parasite co-existence remain unclear for these 2 species.

Ups and downs of infections with the broad fish tapeworm Dibothriocephalus latus in Europe from 1900 to 2020: Part I.

The broad fish tapeworm, Dibothriocephalus latus (Diphyllobothriidea), is the most frequent causative agent of diphyllobothriosis, a fish-borne zoonosis, in Europe. Diphyllobothriosis is characterized by the transmission of D. latus larvae to humans via the consumption of raw, marinated, smoked or inadequately cooked fish products.

The first records of Spirometra erinaceieuropaei (Cestoda: Diphyllobothriidae), a causative agent of human sparganosis, in Latvian wildlife.

Diphyllobothriid tapeworms of the genus Spirometra are causative agents of sparganosis, food-borne zoonotic parasitic disease. They have been recorded in broad spectrum of hosts, including humans, in all continents except Antarctica. Spirometra tapeworms have been intensively studied in several Asian countries; however, they have been rather neglected in Europe.

Comparative analysis of monozoic fish tapeworms Caryophyllaeus laticeps (Pallas, 1781) and recently described Caryophyllaeus chondrostomi Barčák, Oros, Hanzelová, Scholz, 2017, using microsatellite markers.

The monozoic tapeworm Caryophyllaeus laticeps has been characterized by five markedly different morphotypes largely corresponding to different fish hosts. Recently, the most distinct morphotype 4 from the common nase Chondrostoma nasus was studied in more details resulting in description of a new species Caryophyllaeus chondrostomi. The molecular study based on mitochondrial cox1 and ribosomal lsrDNA did not reveal any interspecific differences between C.

Development of microsatellite loci in zoonotic tapeworm Dibothriocephalus latus (Linnaeus, 1758), Lühe, 1899 (syn. Diphyllobothrium latum) using microsatellite library screening.

The broad fish tapeworm Dibothriocephalus latus is a causative agent of human food-borne disease called diphyllobothriosis. Medical importance, scattered geographical distribution and unknown origin of D. latus in Europe and North America make this species to be an interesting model for population genetics.

Tour around the globe: The case of invasive tapeworm Atractolytocestus huronensis (Cestoda: Caryophyllidea), a parasite of common carp.

The monozoic tapeworm Atractolytocestus huronensis Anthony, 1958 (Cestoda: Caryophyllidea), an intestinal parasite of the common carp, is characterized by its invasive character and potential to colonize new territories. It was initially described from North America and has also been found in several European countries. The most recent findings of A.

A genetic structure of novel population of Fascioloides magna from Poland, Podkarpackie Province, indicates an expanding second European natural focus of fascioloidosis.

The veterinary important parasite of ruminants, giant liver fluke Fascioloides magna(Trematoda: Fasciolidae), isolated from liver of farmed fallow deer (Dama dama) from Podkarpackie Province (southeastern Poland) was genotypized by mitochondrial cytochrome c oxidase (cox1) and nicotinamide dehydrogenase (nad1) markers. The data on this newly emerged population were compared with mitochondrial haplotypes of recently detected Polish population of F. magna from Lower Silesian Wilderness (southwestern Poland) and with European populations of the parasite from all three natural foci; northern Italy, Czech Republic and the Danube floodplain forests.

Roles of the Nfu Fe-S targeting factors in the trypanosome mitochondrion.

Iron-sulphur clusters (ISCs) are protein co-factors essential for a wide range of cellular functions. The core iron-sulphur cluster assembly machinery resides in the mitochondrion, yet due to export of an essential precursor from the organelle, it is also needed for cytosolic and nuclear iron-sulphur cluster assembly. In mitochondria all [4Fe-4S] iron-sulphur clusters are synthesised and transferred to specific apoproteins by so-called iron-sulphur cluster targeting factors.

Molecular characterization of Fascioloides magna (Trematoda: Fasciolidae) from south-western Poland based on mitochondrial markers.

The giant liver fluke, Fascioloides magna, is a veterinary important liver parasite of free living and domestic ruminants. This originally North American parasite was introduced along with its cervid hosts to Europe where it has established three permanent natural foci - in northern Italy, central and southern parts of the Czech Republic and the Danube floodplain forests. The first record on fascioloidosis in Poland originated from the Lower Silesian Forest in south-western Poland and since then an occurrence of F.

Cytogenetics of Aspidogaster limacoides (Trematoda, Aspidogastrea): karyotype, spermatocyte division, and genome size.

A detailed cytogenetic analysis of the aspidogastrean fluke Aspidogaster limacoides revealed a karyotype consisting of six medium-sized chromosome pairs. The first and the last pairs were two-armed while four remaining were one-armed; 2n = 12, n = 1 m + 1 m - sm + 4a. Fluorescence in situ hybridization with 18S ribosomal DNA (rDNA) probe detected a single cluster of ribosomal genes (NOR) located in pericentromeric regions of the long arms of the third chromosome pair in a site of secondary constriction apparent in meiotic prophase, especially in diplotene.

Development of microsatellite markers in Caryophyllaeus laticeps (Cestoda: Caryophyllidea), monozoic fish tapeworm, using next-generation sequencing approach.

Caryophyllaeus laticeps (Pallas 1781) (Cestoda: Caryophyllidea) is a monozoic tapeworm of cyprinid fishes with a distribution area that includes Europe, most of the Palaearctic Asia and northern Africa. Broad geographic distribution, wide range of definitive fish hosts and recently revealed high morphological plasticity of the parasite, which is not in an agreement with molecular findings, make this species to be an interesting model for population biology studies. Microsatellites (short tandem repeat (STR) markers), as predominant markers for population genetics, were designed for C.

Conflict between morphology and molecular data: a case of the genus Caryophyllaeus (Cestoda: Caryophyllidea), monozoic tapeworms of cyprinid fishes.

Molecular analysis of an extensive specimen collection of morphologically distinct tapeworms of the genus Caryophyllaeus Gmelin, 1790 (Cestoda: Caryophyllidea), parasites of cyprinid fishes in the Palaearctic Region, brought evidence of host-related plasticity in critical morphological characters widely used for species circumscription and classification of these tapeworms. The results obtained here do not support the traditionally used morphological concept of species-defining characters of the order Caryophyllidea Carus, 1863, especially due to high morphological plasticity of the scolex and the anterior end of the body. Several morphotypes within both Caryophyllaeus laticeps (Pallas, 1781) and Caryophyllaeus brachycollis Janiszewska, 1953 generally corresponding to different hosts and geographical regions, were recognised likely suggesting host- and geography-related intraspecific morphological variability.

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.

Development and characterization of multiplex panels of polymorphic microsatellite loci in giant liver fluke Fascioloides magna (Trematoda: Fasciolidae), using next-generation sequencing approach.

The microsatellite markers were designed for the giant liver fluke, Fascioloides magna, veterinary important liver parasite of free-living and domestic ruminants. Due to its geographic distribution (five enzootic regions across USA and Canada, three permanent European foci) and invasive character, F. magna is an interesting model for population genetics.
