Genetic identification and insights into the ecology of Contracaecum rudolphii A and C. rudolphii B (Nematoda: Anisakidae) from cormorants and fish of aquatic ecosystems of Central Italy [PDF]
Contracaecum rudolphii (s. l.) is a complex of sibling species of anisakid nematodes having the fish-eating birds belonging to the Family Phalacrocoracidae as final hosts. The great cormorant Phalacrocorax carbo sinensis is parasitized by C. rudolphii A and C. rudolphii B. Adults and L4 specimens of C. rudolphii (s.

Genetic evidence for the existence of sibling species within Contracaecum rudolphii (Hartwich, 1964) and the validity of Contracaecum septentrionale (Kreis, 1955) (Nematoda: Anisakidae) [PDF]
Specimens of Contracaecum rudolphii sensu lato (s.l.) (Nematoda: Anisakidae) from Phalacrocorax carbo sinensis from northeastern and central Italy were characterised genetically and compared with those from Phalacrocorax aristotelis from Galician coasts, Spain (identified as C.

Molecular identification of Contracaecum rudolphii A and B (Nematoda: Anisakidae) from cormorants collected in a freshwater ecosystem of the pre-alpine area in Northern Italy [PDF]
Contracaecum rudolphii (s.l.) is a complex of sibling species with different genetic structure and ecological preference. This study reports the presence of specimens of Contracaecum rudolphii (s.l.) from sedentary and wintering cormorants (Phalacrocorax carbo sinensis) from the pre-mountain area of the Alps in Northern Italy, an important crossroads ...

Experimental studies on the development of Contracaecum rudolphii (Nematoda: Anisakidae) in copepod and fish paratenic hosts [PDF]
The larval development of the nematode Contracaecum rudolphii (Rudolphi, 1819), a common parasite of the proventriculus of cormorants, was experimentally studied. Within the eggs cultivated in freshwater under laboratory temperatures of 20-22 degrees C, the developing larva undergoes two moults on days 4-5, attaining the third larval stage. Most of the

Although numerous genetically isolated entities within Contracaecum rudolphii sensu lato are presently defined, information on the distribution and ecology of these groups is nonetheless in demand. In the present study, information based upon DNA sequence data (restriction analysis and sequencing of rDNA) on the distribution of the species C. rudolphii

Cadmium and lead concentrations in Contracaecum rudolphii (Nematoda) and its host, the cormorant Phalacrocorax carbo (Aves) [PDF]
There are a variety of ways to assess the environmental impacts on parasites (Lafferty D. 1997: Parasitol. Today 13: 251-255). Recent studies on endoparasites of fish have revealed that several helminths (mainly acanthocephalans, and to a lesser degree tapeworms) from the intestine of their definitive hosts bioconcentrate heavy metals above the values ...

The aims of this study were to examine specimens of Contracaecum rudolphii from Australian hosts, both morphologically and genetically, based on the ITS-1 and ITS-2 sequence data, to provide a re-description for the species and to investigate the genetic make-up of this species in Australia. Morphological examination of adult specimens of C.

Contracaecum rudolphii Hartwich (Nematoda, Anisakidae) from the Neotropical Cormorant, Phalacrocorax brasilianus (Gmelin) (Aves, Phalacrocoracidae) in southern Brazil [PDF]
The present report is part of a larger study on the helminth fauna of Neotropical Cormorants, Phalacrocorax brasilianus (Gmelin, 1789) in Brazil, particularly, in the southernmost State of Rio Grande do Sul. The nematodes which were found loose in the proventriculus/ventriculus or in groups of adults of different ages and of L3 and L4 larval stages ...

Parameters related to the occurrence, aggregation, and population structure of the nematode Contracaecum rudolphii Hartwich, 1964 , in the great cormorant ( Phalacrocorax carbo ) from northeastern Poland were analyzed. A total of 491 birds of different ages (adults, immatures, and nestlings) was examined; the cormorants studied were taken from both ...
