Molecular Identification of Two Strains of Third-Stage Larvae of Contracaecum rudolphii Sensu Lato (Nematoda: Anisakidae) From Fish in Poland

Journal of Parasitology, 2007
Contracaecum sp. larvae (L3) from fish were identified using nucleotide sequences of the internal transcribed spacers ITS-1 and ITS-2 of the ribosomal DNA. The nematode larvae originated from fish in a freshwater situation (crucian carp Carassius carassius, from Selment Wielki Lake in Mazury, northeastern Poland) and a brackish-water region (Caspian ...

[Antioxidants of Contracaecum rudolphii (Nematoda)].

Wiadomosci parazytologiczne, 2009
Contracaecum rudolphii is the parasitic nematode of fish-eating birds. In the extracts from female, male and larvae L3 and L4 isolated from the alimentary tracts of black cormorants the activity of five antioxidant enzymes: superoxide dismutase (SOD), glutathione peroxidase (GPX), glutathione transferase (GST), glutathione reductase (GR), catalase (CAT)

Infection by Contracaecum rudolphii (Nematoda: Anisakidae) in the Neotropic cormorant Phalacrocorax brasilianus, and fishes from the estuary of the Valdivia river, Chile

Studies on Neotropical Fauna and Environment, 2000
Seasonal parameters of infection by the nematode Contracaecum rudolphii in the Neotropic cormorant Phalacrocorax brasilianus (Phalacrocoracidae) and their relation with feeding and infection in fishes from River Valdivia, Chile, were determined. The prevalences of infection in birds were similar during seasons, whereas mean intensity and percentages of

Development of larvalContracaecum rudolphiiHartwich, 1964 (Ascaridida: Anisakidae) in experimentally infected goldfish (Carassius auratusL., 1758)

Journal of Helminthology, 2009
AbstractLaboratory-bred goldfish were experimentally infected withContracaecum rudolphii, either directly (with nematode larvae) or indirectly via infected zooplankton. Intensity and prevalence of infection were markedly higher in fish exposed to the infected zooplankton than in goldfish exposed to nematode larvae.

Further studies on Contracaecum spasskii Mozgovoi, 1950 and C. rudolphii Hartwich, 1964 (sensu lato) (Ascaridida: Anisakidae) from piscivorous birds in China

Systematic Parasitology, 2013
Contracaecum spasskii Mozgovoi, 1950, collected from the great crested grebe Podiceps cristatus (Linnaeus) (Podicipediformes: Podicipedidae), is redescribed using both light and, for the first time, scanning electron microscopy. Contracaecum spasskii differs from its congeners by having marked transverse cuticular ...

Activity of selected hydrolases in excretion-secretion products and extracts of adult Contracaecum rudolphii.

Wiadomosci parazytologiczne, 2006
Enzymes contained in excretion-secretion (ES) products of parasites released to the environment play multiple roles: they facilitate hatching and moulting of larvae, enable a parasite to migrate within tissues, inhibit blood coagulation, defend the parasite from host's immunological response, and enhance feeding and nutrition.

Molecular evidence for the occurrence of Contracaecum rudolphii A (Nematoda: Anisakidae) in shag Phalacrocorax aristotelis (Linnaeus) (Aves: Phalacrocoracidae) from Sardinia (western Mediterranean Sea)

Parasitology International, 2008
Specimens of Contracaecum rudolphii Hartwich, 1964 (Nematoda: Anisakidae) from Phalacrocorax aristotelis (Linnaeus) from the Archipelago of La Maddalena (Sardinia, western Mediterranean Sea) were characterised genetically and compared with C. rudolphii A sensu D'Amelio et al. 1990 and C. rudolphii B sensu D'Amelio et al.

[First record of Paradilepis Scolecina (Cestoda: Dilepididae) and Contracaecum rudolphii (Nematoda: Anisakidae) in the Curonian Lagoon of Baltic Sea].

Parazitologiia, 2009
Metacestodes of Paradilepis scolecina (Rudolphi, 1918) Hsu, 1935 and juveniles of the nematode Contracaecum rudolphii Hartwich, 1964 have been found for the first time in the bream Abramis brama L. from the Curonian Lagoon of Baltic Sea. Descriptions and measurements for both parasite species are given. High infestation of bream with these parasites in

Effect of temperature, NaCl concentration and aeration of solutions on the survivability of II stage larvae of Contracaecum rudolphii Hartwich, 1964

Wiadomości Parazytologiczne, 2010
Determinations were carried out for the effect of temperature, NaCl concentration and aeration of solutions on the survivability of stage II larvae of Contracaecum rudolphii nematode. Stage II larvae hatched from egg shells were placed in tap water as well as in 1% and 3% solutions of NaCl.
