further study of contracaecum pelagicum (nematoda: anisakidae) in spheniscus magellanicus (aves: spheniscidae) from argentinean coasts.	the anisakid species contracaecum pelagicum johnston and mawson, 1942, is reported for first time at 2 different sites on the argentine coast (peninsula valdés, 42 degrees 04's, 63 degrees 38'w and mar del plata, 38 degrees 05's, 57 degrees 38'w), parasitizing the magellanic penguin, spheniscus magellanicus foster. morphometric analysis and further studies of adult specimens of c. pelagicum were done using light and scanning electron microscopy. the presence of bifurcated interlabia differentiat ...	2007	17436954
genetic and morphological evidences for the existence of a new species of contracaecum (nematoda: anisakidae) parasite of phalacrocorax brasilianus (gmelin) from chile and its genetic relationships with congeners from fish-eating birds.	abstract contracaecum australe n. sp. is described from the neotropic cormorant phalacrocorax brasilianus in chile based on morphology and the sequence analyses of multiple loci, i.e., mitochondrial cytochrome oxidase 2, mtdna cox-2 , the small subunit of the mitochondrial ribosomal rna gene, rrns , and the its-1 and its-2 regions of nuclear ribosomal dna. moreover, sequence analysis of the same genes was carried out on the morphospecies contracaecum chubutensis garbin et al. (2008) from phalacr ...	2011	21506861
ecological aspects of helminth fauna of magellanic penguins, spheniscus magellanicus (aves: spheniscidae), from the northern coast of the state of são paulo, brazil.	the aim of the present study was to evaluate the helminth fauna found in the magellanic penguin, spheniscus magellanicus, relating parasite population and community ecological parameters to life aspects of the host species. the study involved 237 specimens of s. magellanicus taken from the northern shore of the state of são paulo (23° 46' s, 45° 57' w) and southern shore of the state of rio de janeiro (23° 02' s, 44° 13' w), brazil. the following helminth fauna were found: the nematode contracae ...	2013	23644789
molecular identification and larval morphological description of contracaecum pelagicum (nematoda: anisakidae) from the anchovy engraulis anchoita (engraulidae) and fish-eating birds from the argentine north patagonian sea.	anisakids use invertebrates as paratenic and/or intermediate hosts as a basic feature of larval transmission. the third-stage larva usually develops in invertebrates which are prey items of finfish paratenic hosts. contracaecum larvae molt twice inside the egg and hatch as free third-stage larvae ensheathed in the second-stage larval cuticle. copepods act as paratenic or obligatory hosts, usually ingesting these free l3 larvae, and fish act as intermediate/paratenic or metaparatenic hosts preyin ...	2013	23500719
molecular and morphological characterization of contracaecum pelagicum (nematoda) parasitizing spheniscus magellanicus (chordata) from brazilian waters.	three new sequences of mitochondrial cytochrome c-oxidase subunit 2 (mtdna cox-2) from c. pelagicum parasite of spheniscus magellanicus, the magelanicus penguin, were determined from brazilian waters. the sequences presented 99 and 98% of similarity with c. pelagicum sequences from argentina, deposited on genbank for the same genetic region and with a strong statistical support inferred from the phylogenetic tree. the morphological and ultrastructural studies that were carried out confirmed the ...	2014	24728364
