| 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 |
| levels of infection of gastric nematodes in a flock of great cormorants ( phalacrocorax carbo) from lake biwa, japan. | a high prevalence (86.7%) of various species of nematodes was observed in the stomach of great cormorants living in lake biwa, japan. there were varying numbers of adults belonging to two common genera, eustrongylides jagerskiold 1909 (nematoda: dioctophymatidae) and contracaecum railliet & henry 1912 (nematoda: anisakidae). the first included common adenophorean nematodes comprising a single species, eustrongylides tubifex and the second comprised ascaroid nematodes that contained four named sp ... | 2011 | 21342602 |
| mutation scanning-coupled sequencing of nuclear ribosomal dna spacers as a tool for the specific identification of different contracaecum (nematoda: anisakidae) larval types. | in the present study, various morphotypes of contracaecum (nematoda) larvae in different developmental stages were described and then genetically characterised using sequence data obtained from the first and second internal transcribed spacers (its-1 and its-2) of nuclear ribosomal dna (rdna). the alignment of its-1 and its-2 sequence data for larvae investigated with those from well characterised adults in previous studies showed that fourth-stage contracaecum larvae from the australian pelican ... | 2010 | 20933594 |
| redescription and genetic characterization of selected contracaecum spp. (nematoda: anisakidae) from various hosts in australia. | in the present study, five species of contracaecum railliet & henry 1912 (nematoda: ascaridida), including contracaecum bancrofti, contracaecum microcephalum, contracaecum variegatum, contracaecum eudyptulae, and contracaecum ogmorhini, were redescribed using light and scanning electron microscopy. in addition, in order to elucidate their taxonomic status, first and second internal transcribed spacers (its-1 and its-2, respectively) of nuclear ribosomal dna of each morphospecies were characteriz ... | 2009 | 19214573 |
| [the helminth fauna of indigenous white storks (ciconia ciconia)]. | 120 carcasses of white storks originating from the federal countries saxonia-anhalt and brandenburg where examined between 1994 and 2000 for internal parasites. the established parasite spectrum consisted of 8 trematode (tylodelphis excavata, chaunocephalus ferox, cathemasia hians, echinostoma revolutum, echinoparyphium sp., monilifer spinulosus, ignavia ciconiae and brachylaimus sp.), 4 cestode (anomotaenia discoidea and 3 hymenolepidae species) and at least 3 nematode species (capillaria spp., ... | 2002 | 12481650 |
